Re: Boston-Logan International Airport 2016 Environmental Data Report - EEA #3247 
Dear Secretary Beaton and Director Buckley: 
The Massachusetts Port Authority (Massport), is pleased to submit this 2016 Environmental Data
Report (EDR). As outlined in our recent Notice of Project Change (NPC) and the NPC Certificate dated
March 9, 2018, Massport requested Executive Office of Energy and Environmental Affairs (EEA)
approval to substitute the planned 2016 Environmental Status and Planning Report (ESPR) with a 
2016 EDR , due to changing circumstances and uncertain trends, as more fully described below. 
As described in this EDR and the NPC, Logan Airport is in another phase of transition. Several
factors lead to Massport’s conclusion that 2016 was not the appropriate baseline for the next ESPR
which will include forecasting of future operational and environmental conditions. These factors
include (1) rapidly growing domestic and international passenger demand, (2) the formal
introduction in early 2017 of transportation network companies (TNC) such as Uber and Lyft, and (3)
use of the Federal Aviation Administration’s (FAA) new noise and air quality model. 
Accordingly, with EEA approval, Massport has prepared the 2016 EDR as a continuation of our
longstanding commitment to publish detailed cumulative analyses of environmental conditions. This
includes detailed information on passenger activity levels and aircraft operations; ground access;
planning activities; and updates on our mitigation programs. A few of the key activity influences and
operational/environmental findings are summarized below. 
• Passenger Growth . Passenger activity at Logan Airport has continued to grow faster than
previous forecasts; both 2016 and 2017 achieved new passenger level peaks. This growth is
being experienced across the U.S., but more prominently here in Boston due to a strong regional
economy based primarily on business, education, healthcare, and tourism. 
While Logan has also experienced a growth in aircraft operations, passenger growth continues
to far outpace the increase in aircraft operations. This trend of more passengers in fewer flights
remains consistent with our recent experience, and it supports Massport’s long-standing goals
to reduce overall operating and environmental impacts at Logan Airport. 
• Ground Access . Logan Airport, like many airports across the U.S., is experiencing a dramatic
shift in ground access modes. TNCs such as Lyft and Uber did not exist a few years ago are
becoming prominent providers of Logan Airport passenger ground access/egress. This new

The Honorable Matthew Beaton, Secretary Page 2 May 15, 2018 
mode is already beginning to have a dramatic impact on how our passengers arrive and depart
Logan Airport. TNCs formally began picking up at Logan Airport in February 2017; some early
discussion of those effects is contained in this 2016 EDR , but the forthcoming 2017 ESPR will
provide a better indication of future ground access mode share trends than was available for
this EDR. 
• New FAA Noise and Air Quality Model . The 2016 noise analysis marks the first time Massport
has used the Federal Aviation Administration’s (FAA) new Aviation Environmental Design
Tool (AEDT). As described in the 2015 EDR , AEDT does not incorporate a number of the Logan
Airport-specific model adjustments incorporated in the legacy Integrated Noise Model (INM).
Therefore, until the 2016 analysis, when some broader adjustments to AEDT were made by
FAA, Massport had deferred its use in the annual EDRs. The 2016 EDR uses AEDT for the first
time.
Similarly, AEDT is now used for the detailed air quality analyses. As with other model changes,
AEDT has many new emission factors that influence the annual results. For that reason, this
EDR presents 2016 air quality findings using both the legacy EDMS ( Emissions and
Dispersion Modeling System ) model and AEDT and discusses year-to-year differences based on
operational levels and model differences. 
In consideration of the adjusted filing sequence and schedule and in accordance with the NPC
Certificate, the 2016 EDR strives to provide a broader context of these evolving factors and also
provides available updates on recent and ongoing Logan Airport projects and longer-range planning
considerations. This includes the Terminal E Modernization Project, which is now in final design, and
the Logan Airport Parking Project and its role in Massport strategies to reduce drop-off/pick-up trips
which cause unnecessary vehicle miles traveled and associated emissions. 
The EDR provides an update on the status of those and other ongoing Logan Airport projects,
planning and environmental initiatives as well as previewing planned and potential new projects and
programs. This EDR also contains the detailed annual data reporting on Logan Airport activity,
planning, ground access, noise, air quality, sustainability, water quality, and environmental
mitigation tracking. Where relevant, we also discuss evolving topics since filing of the 2015 EDR . In
coordination with the MEPA Office and the MA Department of Energy Resources, this EDR also
includes several new greenhouse gas (GHG) reporting metrics. 
EDR Content and Structure 
The 2016 EDR responds to the Secretary’s Certificate on the Boston-Logan International Airport 2015
Environmental Data Report , as amended in the Secretary’s March 2018 Certificate on the NPC. The
document reports on the status of airport operations, environmental conditions, and Massport
milestones achieved since 2015 and provides updates on more recent significant Logan Airport
planning activities. The 2016 EDR also updates 2016 conditions for the following categories:

The Honorable Matthew Beaton, Secretary Page 3 May 15, 2018 
• Passenger levels, aircraft operations, aircraft fleets, and cargo volumes; 
• Planning, design, and construction activities at Logan Airport; 
• Regional transportation statistics and initiatives; 
• Key environmental indicators (Ground Access, Noise Abatement, Air Quality/Emissions
Reduction, and Water Quality/Environmental Compliance and Management); 
• Status of Logan Airport project mitigation; and 
• Sustainability initiatives. 
The 2016 EDR includes the Secretary’s Certificate on the Boston-Logan International Airport 2015 EDR 
and 2018 NPC and associated comment letters. Recent certificates received on the Terminal E
Modernization Project Environmental Notification Form and Draft and Final Environmental Impact Reports 
are also included. In addition to the distribution list and supporting technical appendices (included
in the attached CD), a proposed scope for the 2017 ESPR is included as Appendix C. 
Review Period, Distribution, and Consultation 
A 30-day public comment period for the 2016 EDR will begin on May 23, 2018, the publication date of
the next Environmental Monitor, and will end on June 22, 2018. The distribution list included as
Appendix D indicates which listed parties will receive a digital and/or printed copy of this 2016 EDR .
As with the recent EDRs, ESPRs and other Massport environmental filings, this 2016 EDR is presented
in its entirety on Massport’s website (http://www.massport.com/massport/about-massport/project-
environmental-filings/). 
A public information meeting on the 2016 EDR is scheduled for Tuesday June 12, 2018 at 6:00 PM in the
Cathy Leonard-McLean Community Room on the 1st floor of the Logan Airport Rental Car Center.
Additional copies of the 2016 EDR may be obtained by calling (617) 568-3546 or emailing 
mgove@massport.com during the public comment period. 
We look forward to your review of this document and to consultation with the MEPA Office and
other reviewers in the coming weeks. Please feel free to contact me at (617) 568-3524, if you have any
questions. 
Sincerely,

Introduction/Executive Summary 
Introduction 
The Massachusetts Port Authority (Massport) is pleased to continue its practice of providing an extensive, almost
three-decade record of Boston-Logan International Airport (Logan Airport or Airport) environmental trends,
development planning, operations and passenger levels, and Massport’s mitigation commitments in this Logan
Airport 2016 Environmental Data Report (EDR) . Logan Airport, owned and operated by Massport, is New
England’s primary international and domestic airport. This 2016 EDR is one in a series of annual environmental
review documents submitted to the Secretary of the Executive Office of Energy and Environmental Affairs (EEA) in
accordance to the Massachusetts Environmental Policy Act (MEPA) 1 Office since 1979 to report on the cumulative
environmental effects of Logan Airport’s operations and activities. Logan Airport is the first airport in the nation
for which an annual environmental report card on airport activities was prepared, and Massport continues to be a
leader in environmental reporting. 
Approximately every five years, Massport prepares
an Environmental Status and Planning Report
(ESPR), which provides a historical and prospective
view of Logan Airport. EDRs, prepared annually in
the intervals between ESPRs, provide a review of
environmental conditions for the reporting year
compared to the previous year. Over the long-
term, environmental impacts associated with Logan
Airport have been decreasing, as reported on each
year in the EDR/ESPR filings. This 2016 EDR follows
the 2015 EDR and reports on 2016 conditions. 
Following the 2015 EDR , the next annual report
was originally scheduled to be a 2016 ESPR. With
prior approval of the EEA Secretary, Massport has
prepared an EDR for 2016. In the past few years,
passenger demand trends for air travel have been rapidly increasing, and the air carrier landscape is changing.
Additionally, ground transportation at Logan Airport has also changed rapidly with the introduction of
transportation network companies (TNCs) such as Uber and Lyft. Due to these rapid changes, 2016 does not
serve as a reasonable baseline for prediction of longer-range impact assessment. Therefore, Massport will

prepare a 2017 ESPR, which will include an updated future forecast and a better understanding of future ground
transportation options to and from Logan Airport, after a full year of data have been collected. 
The scope for this document was established by the Secretary‘s Certificate dated February 17, 2017, as amended
on March 9, 2018, which is included in Appendix A, MEPA Certificates and Responses to Comments . This 2016 EDR 
fulfills all the requirements laid out in the Secretary’s 2018 Certificate. This 2016 EDR includes reporting on the
following categories and provides detailed responses to comments on the Secretary’s Certificate. Future year
forecasts and impact assessments will be provided in the 2017 ESPR . 
This 2016 EDR updates and compares the data presented in the 2015 EDR , and presents the following
information for 2016: 
To enhance the usefulness of this 2016 EDR as a reference document for reviewers, this report also presents
historical data on the environmental conditions at Logan Airport dating back to 1990, in instances where
historical information is available.

Introduction/Executive Summary 1-3 
Logan Airport Planning Context 
Logan Airport plays a key role in the metropolitan Boston and New England passenger and freight transportation
networks. The Airport boundary encompasses approximately 2,400 acres in East Boston and Winthrop, including
approximately 700 acres underwater in Boston Harbor. Logan Airport, shown in Figures 1-1 and 1-2 , is one of
the most land-constrained airports in the nation, and is surrounded on three sides by
Boston Harbor. 
Logan Airport is close to downtown Boston and is accessible by two public transit lines,
five direct bus lines, and a well-connected roadway system. Massport also provides Logan
Express bus service to and from Logan Airport for air passengers and employees from
park-and-ride lots in Braintree, Framingham, Woburn, and Peabody. The airfield
comprises six runways, approximately 15 miles of taxiway, and approximately 240 acres of concrete and asphalt
apron. Logan Airport has four passenger terminals (Terminals A, B, C, and E), each with its own ticketing, baggage
claim, and ground transportation facilities. Massport continues to evaluate and implement enhancements to
Logan Airport’s security, operational efficiency, and accessibility to and from the Boston metropolitan area, while
carefully monitoring the environmental effects of Logan Airport operations. 
In 2016, over 17,000 people were employed at Logan Airport. This included approximately 1,200 Massport airport
staff and administrative employees. The Massachusetts Department of Transportation (MassDOT) Aeronautics
Division’s Massachusetts Statewide Airport Economic Impact Study Update found that in 2014, Logan Airport
supported approximately 132,000 direct and indirect jobs and contributed nearly $13.3 billion annually to the
local economy; this includes all on-Airport businesses, construction, visitor, and multiplier impacts. 2 
In 2016, Logan Airport was the 17 th busiest U.S. commercial airport by number of commercial passengers, and
the 18 th busiest U.S. commercial airport by aircraft movements. 3 Boston is an important domestic and
international destination, and air carriers seek to expand international service at Logan Airport based on current
and anticipated passenger demand. New international service in the last five years alone has contributed more
than $1.3 billion per year to the local economy and $49 million in new incremental tax revenue through income
and sales. 4 
Logan Airport fulfills a number of roles in the local, New England, and national air transportation networks. It is
the primary airport serving the Boston metropolitan area, the principal New England airport for long-haul
services, and a major U.S. international gateway airport for transatlantic services.

Logan Airport is a Regional Economic Driver 
Logan Airport plays an important role in the New England area and is the largest airport in the six-state
region (see Figure 1-3 ). Located in Massachusetts, which is home to 14.8 million residents, the Airport
draws passengers from across New England, with its primary catchment area consisting of five
Massachusetts counties: Essex, Middlesex, Norfolk, Plymouth, and Suffolk (which includes the City of
Boston). According to the most recently available statistics, 4.4 million people reside in this five-county
area (see Table 1-1 ).

Introduction/Executive Summary 1-8 
Logan Airport’s Regional Market 
The area surrounding Logan Airport has demonstrated strong economic growth over the last 10 years,
reflecting the interdependent relationship between the regional economy and Logan Airport. The robust
regional economy drives passenger and cargo demand, both inbound and outbound, for the Airport.
Similarly, the Airport’s air service enables businesses to serve customers outside of New England as well as
tourists who use services provided by local businesses. 
The Boston metropolitan area is home to a broad range of industries, with healthcare and social
assistance, educational services, and professional, scientific, and technology services (which include
Boston’s growing biotech industry) accounting for the largest share of employees. 5 In 2016, Boston was
declared the “#1 city in the U.S. for fostering entrepreneurial growth and innovation.” 6 The contribution of
innovation and business start-ups is also evident in the latest 2017 year-to-date economic growth
estimates and reflects trends in increased employment and high-tech industries. The outlook for the state
is good. In the third quarter of 2017, the Commonwealth of Massachusetts avoided the dampening effect
of Hurricanes Harvey and Irma that affected much of the United States, growing by 5.9 percent. 7 Forecasts
of Commonwealth gross domestic product (GDP) for the fourth quarter of 2017 indicate continued
growth of approximately 3.3 percent.

Introduction/Executive Summary 1-9 
Another reflection of the strength of the Airport’s regional market is its relatively low unemployment rate.
The Boston metropolitan area has consistently maintained a lower unemployment rate than that of the
Commonwealth and the entire country (see Figure 1-5 ). In 2016, the Boston MSA had an unemployment
rate of 3.4 percent, which is lower than the rate in the Commonwealth (3.7 percent) and the country
(4.9 percent). Even during the economic downturn years of 2008-2010, Boston and the Commonwealth
experienced unemployment rates below the national average. 
The Airport not only serves a growing population, but a high earning one as well. Per capita income in
2016 was $64,617 (2009 U.S. dollars) in the Airport’s primary service area, 10.9 percent higher than the
Commonwealth and 44.8 percent higher than the national average. 
Logan Airport’s Regional Economic Impacts 
Logan Airport and the airport industry are a major economic driver in the state and region. The 
Massachusetts Statewide Airport Economic Impact Study Update, completed by MassDOT in 2014, 8 
estimates that aviation contributes $16.6 billion in output to the Massachusetts economy annually (see 
Table 1-2 ); of this output, 80.7 percent of this is due to Logan Airport alone. 9 Total output includes
on-Airport businesses, construction, visitor, and multiplier effects (see Figure 1-6 ). 10

9 Ibid . 
10 Multiplier effects refer to the recirculation of money in the local economy after initially being spent by the Airport, its tenants,
or tourists. This recirculation increases the overall impact of the Airport’s operation in the local economy.

Boston-Logan International Airport 2016 EDR 
Introduction/Executive Summary 1-10 
On-Airport business output includes airport administration, airlines, concessionaires, and other companies
that operate at Logan Airport. Implementation of the Capital Improvement Plan (as discussed in
Chapter 3, Airport Planning ). The visitor impacts represent the expenditure on hotels, rental cars,
restaurants, and attractions of tourists arriving at the Airport. Millions of people travel to Massachusetts,
particularly to the City of Boston, every year to enjoy the rich historic and cultural heritage, attend cultural
or sporting events, conduct business, visit recreational areas, and attend conferences at one of the City’s
convention centers. Over 1.8 million overseas visitors and 25 million domestic visitors 11 traveled to the
state in 2016. 12 
In addition to direct effects, Logan Airport generates multiplier effects in the surrounding region that
consist of two categories: 1) the expenditure of Airport tenants; and 2) the re-spending of wages by
Airport employees. As a result, money spent at the Airport is re-circulated in the local economy multiple
times. Airport tenants or businesses operating at the Airport purchase goods and services locally (such as
delivery services and food ingredients). The annual wages and benefits (approximately $4.3 billion) of the
more than 132,000 regional employees (see Table 1-2 ) supported by the Airport are re-spent in the local
community as employees purchase daily necessities. 
The arrival of international visitors has been aided by the growth in non-stop international service at the
Airport, operated by new, foreign-based carriers using cleaner and quieter wide-body aircraft. In 2016,
international visitors spent $2.8 billion in the Commonwealth, a 3.1-percent increase from 2015, on public
transportation, rental cars, food, lodging, entertainment, and retail (see Table 1-3 ). International visitors
supported 19,300 jobs in 2016 with $636.9 million in payroll and benefits.

Introduction/Executive Summary 1-14 
Activity Levels 
Logan Airport continues to be an important origin and destination (O&D) 14 airport both nationally and
internationally. The Airport is also one of the fastest growing major U.S. airports, in terms of number of
passengers, over the past several years. 15 There has been growth in both domestic and international
passenger numbers. Additional trends in new aircraft technology, allowing for smaller and more
fuel-efficient aircraft on international routes, are also expected to continue to benefit mid-size O&D
markets like Boston. Notable 2016 highlights and key findings on passenger activities, aircraft operations,
and cargo volumes include: 
 In 2016, U.S. passenger traffic grew by 3.8 percent, whereas Logan Airport experienced a
passenger growth of 8.5 percent, more than double during the same period. 16 
 Overall, Logan Airport served 55 non-stop international destinations in 2016, compared to 47 in
2015. 17 
 From 2000 to 2016, the annual number of passengers at Logan Airport increased by 30.9 percent,
while the annual number of aircraft operations decreased by 19.8 percent (see Figure 1-9 ). 
 The total number of air passengers increased by 8.5 percent to 36.3 million in 2016, compared to
33.4 million in 2015 (see Figure 1-10 ). The 2016 passenger level represents a new record high for
Logan Airport.

14 “Origin and destination” traffic refers to the passenger traffic that either originates or ends at a particular airport or market. A
strong O&D market like Boston generates significant local passenger demand, with many passengers starting their journey and
ending their journey in that market. O&D traffic is distinct from connecting traffic, which refers to the passenger traffic that
does not originate or end at the airport but merely connects through the airport en route to another destination. 
15 Between 2010 and 2016, Logan Airport was the eighth fastest growing airport in the U.S. in terms of domestic O&D traffic (U.S.
DOT O&D Survey).

 While the numbers of both domestic and international passengers are increasing, international
passenger demand continues to increase at a faster rate than domestic passenger demand. Total
international passengers at Logan Airport increased from 5.5 million in 2015 to 6.6 million in 2016,
a 19-percent increase. Annual domestic passengers’ activity levels increased from 27.8 million in
2015 to 29.6 million in 2016, 18 a 6.4-percent increase. The strong international passenger growth
was driven by the economic attractiveness of the metropolitan Boston region and the strength of
Boston as an O&D market.

Boston-Logan International Airport 2016 EDR 
Introduction/Executive Summary 1-17 
 The total number of aircraft operations at Logan Airport increased from 372,930 in 2015 to
391,222 in 2016, a 4.9-percent increase. Despite the increase, aircraft operations at Logan Airport
remained well below the 487,996 operations in 2000 and the historical peak of 507,449 achieved
in 1998. In 1998, Logan Airport served 26.5 million air passengers, compared to 36.3 million air
passengers in 2016, which saw 116,227 fewer operations. 
 Passenger aircraft operations accounted for 90.4 percent of total aircraft operations in 2016.
While domestic operations remain the largest share of commercial operations, 19 international
operations have grown steadily at Logan Airport. In 2016, scheduled domestic operations
increased by 2.6 percent while scheduled international operations increased by 17.9 percent. 
 International passengers made up approximately 18 percent of total Airport passengers in 2016. 
 JetBlue Airways and Delta Air Lines continued to expand services at Logan Airport, increasing their
total operations by 6.9 percent and 6.4 percent respectively in 2016. As Logan Airport’s largest
carrier, JetBlue Airways accounted for 23.4 percent of total passenger aircraft operations and
26.8 percent of total passengers in 2016. 
 General Aviation (GA) operations, which accounted for 7.9 percent of total operations in 2016,
increased by 9.3 percent from 2015. 20 The 30,780 GA operations in 2016 remain below the 35,233
GA operations that Logan Airport handled in 2000. Hanscom Field, Logan Airport’s reliever
airport, handled 120,891 GA operations in 2016. 21 
 Air carrier efficiency continued to increase, with the average number of passengers per aircraft
operation at Logan Airport increasing from 89.7 in 2015 to 92.8 in 2016. The increasing number of
passengers per flight reflects a shift away from smaller aircraft and rising load factors as airlines
continue to focus on capacity control and improvements in efficiency. 
 Total air cargo volume 22 at Logan Airport totaled 640 million pounds in 2016, compared to
606 million pounds in 2015. Approximately 44 percent of Logan Airport’s cargo was carried by
passenger airlines as belly cargo, while 56 percent was carried by all-cargo carriers such as FedEx
and UPS. Dedicated air cargo operations increased from 6,059 in 2015 to 6,680 in 2016, a
10.2-percent increase. 
–––––––––––––––– 
19 Commercial operations include passenger aircraft operations and a small number of all-cargo aircraft operations. 
20 General Aviation (GA) is defined as all aviation activity other than commercial airline and military operations. 
21 Hanscom Field, a full-service GA airport, plays a critical role as a corporate reliever for Logan Airport. 
22 Air cargo includes express/small packages, freight, and mail.

Boston-Logan International Airport 2016 EDR 
Introduction/Executive Summary 1-18 
While this annual report was originally scheduled to be a 2016 ESPR, and with prior approval of the
Secretary of EEA, Massport has prepared an EDR for 2016. In the past few years, passenger demand trends
for air travel have been rapidly increasing and the air carrier landscape is changing. Additionally, ground
transportation at Logan Airport has also changed rapidly with the introduction of TNCs, such as Uber and
Lyft. 23 Due to these rapid changes, 2016 does not serve as a reasonable baseline for prediction of
longer-range impacts. 
As part of the ESPR process, Massport typically prepares passenger, operations, and cargo activity
forecasts. It is expected that Logan Airport will reach 40 million annual passengers by 2019. Given this
continued faster than expected passenger growth, Massport will be updating the Logan Airport long-term
passenger forecast in the 2017 ESPR to reflect recent growth at Logan Airport, revised expectations for the
local/national/international economy, and latest industry trends. Preliminary review suggests that future
Logan Airport passenger levels could reach about 46 million annual passengers. The 2017 ESPR will
provide more detailed information and updated forecast numbers to 2030/2035. Additional information is
provided in Chapter 2, Activity Levels. 
Airport Planning 
Logan Airport facilities have been accommodating recent increases in activity and operations on the
airside, but the terminal, roadways, and parking facilities are strained by the increase in passengers. The
2016 reporting year was marked by construction of several projects focused on enhancing the passenger
experience, accommodating increases in passenger activity levels, and improving ground access. Recent
progress on planning initiatives and individual projects at Logan Airport are described below.
Chapter 3, Airport Planning, describes the status of all planning projects . 
Terminal and Airside Projects 
 Terminal E Renovation and Enhancements Project . To accommodate regular service by wider
and longer Group VI aircraft at Terminal E, this project included interior and exterior
improvements. The project reconfigured three existing gates to accommodate Group VI aircraft
(including the Airbus A380 and Boeing 747-8 primarily used by international air carriers). An
addition to the west side of Terminal E allowed passenger holdrooms to accommodate the larger
passenger loads associated with larger aircraft. The project also included modifications to the
airfield to meet required FAA safety and design standards to accommodate the larger aircraft. An
Environmental Assessment (EA) was filed, and FAA issued a Finding of No Significant Impact
(FONSI) on July 29, 2016. Construction was completed in early 2017. 
 Terminal E Modernization Project. The Terminal E Modernization Project will add the three
gates approved in 1996 as part of the International Gateway West Concourse project (EEA #9791),
but never constructed, and an additional four gates to Terminal E. The building will be aligned to 
–––––––––––––––– 
23 Drop-off/pick-up modes can include private vehicles, taxis, and black car services. For example, if an air passenger is dropped
off when s/he departs on an air trip and is picked-up upon their return, that single air passenger generates a total of four
ground-access trips: two for the drop-off trip (one inbound to Logan Airport, one outbound from Logan Airport) and two for
the pick-up trip (one inbound to Logan Airport, one outbound from Logan Airport). The air passenger may be dropped off and
picked up in a private vehicle or in a taxi, TNCs, or black car that may not carry a passenger during all segments of travel to and
from Logan Airport.

Boston-Logan International Airport 2016 EDR 
Introduction/Executive Summary 1-19 
function as a noise barrier between the airside operations and the community. New passenger
handling and passenger holdrooms are being planned, as well as possible additional Federal
Inspection Services (FIS) and Customs and Border Protection facilities to supplement the existing
FIS areas in Terminal E. A connection between Terminal E and the Massachusetts Bay
Transportation Authority (MBTA) Blue Line Airport Station will be constructed to improve
passenger convenience. This connection is currently being studied, and various approaches are
under consideration. Consideration is given to constructing an Automated People Mover (APM),
which ultimately would connect the MBTA Blue Line Station to all the terminals. The APM concept
is in the very early stages of feasibility assessment, and will be more definitive as the Terminal E
Modernization Project design progresses. 
The Terminal E Modernization Project will occupy a portion of the North Cargo Area (NCA) and
will include terminal gates, aircraft parking, hangars, and cargo facilities. Massport filed an
Environmental Notification Form (ENF) in October 2015 and a joint federal Draft Environmental
Assessment (EA)/state Draft Environmental Impact Report (EIR) in July 2016. Massport filed the
Final EA/EIR on September 30, 2016. On November 10, 2016, FAA issued a FONSI. On November
14, 2016, FAA issued a Record of Decision (ROD) on the project, stating that Massport can now
update the Airport Layout Plan (ALP) with the proposed Terminal E Modernization Project. (For
convenience, Massport has provided the Secretary’s Certificates on the ENF and Draft EA/EIR, with
responses to those comments, in Appendix A, MEPA Certificates and Responses to Comments, of
this 2016 EDR. ) The project, including the MBTA connection, is in the design phase and initial
construction will likely begin in 2018. Future ESPRs and EDRs will provide updates as final design
and construction proceed. 
 Terminal C to E Airside Connector. The Terminal C to E Airside Connector provides a greater
post-security connectivity between terminals and to improve flexibility for airlines. In addition, the
Terminal C to E Connector provides a post-security connection between Terminals C and E on the
Departures level. The Connector provides improved passenger circulation within the post-security
concourse(s), additional holdroom space at Terminal E, reconfigured office space, concessions and
concessions support, and a new consolidated location for escalators and stairs. The project was
completed in May 2016. 
 Terminal B Optimization Project. Similar to the recent renovations and improvements at
Terminal B, Pier A, Massport is upgrading its facilities on the Pier B side to meet airlines’ needs
and to enhance the passenger traveling experience. Improvements include an enlarged ticketing
hall, improved outbound bag area and claim hall, expanded concession areas, and expanded
holdroom capacity at the gate. The project will consolidate American Airlines’ operations to one
pier of the terminal (now operating on two different sides of the terminal). All Pier B gates will be
connected post security, the project will also consolidate checkpoint operations for better
passenger throughput and improved passenger experience. Massport prepared a Draft EA in
May 2017 and a Final EA in June 2017. On June 29, 2017, FAA issued a FONSI. Final design is now
complete and construction is underway. Construction is expected to be complete in early 2019. 
 Terminal C Building, Roadway, and Curb Enhancements. Massport is currently evaluating
multifaceted enhancements that would enhance Terminal C facilities and provide a post-security
connector between Terminal B and C; replace aging roadways serving the terminal; and improve
the operation of the Terminal C curb. The enhancements also include replacement of the existing

Boston-Logan International Airport 2016 EDR 
Introduction/Executive Summary 1-20 
canopy on the Departures level. The project would enhance Logan Airport’s ability to efficiently
accommodate current and future passenger volumes by bringing the terminal facilities up-to-date
and improving access, egress, and drop-off/pick-up operations. 
 Hangar Projects. Architectural design commenced in December 2010 for two hangar upgrades in
the North Cargo Area (NCA). The renovated JetBlue Airways hangar opened in 2012. The
American Airlines hangar, formerly occupied by Northwest Airlines, was refurbished in 2013.
Demolition of the former American Airlines hangar (Hangar 16) commenced in 2014 and was
completed in August 2016. 
Enhanced Ground Access 
A series of recent ground access improvement projects have been designed to yield substantial
environmental benefits, particularly in the areas of ground access efficiencies and associated air quality
emissions reductions on-Airport and in East Boston, as documented below: 
 The Rental Car Center (RCC) Southwest Service Area (SWSA) Redevelopment Program
(EEA 14137). The RCC is fully operational and the full benefits of the project began to be realized
in 2014. Consolidation of rental car operations and associated shuttle bus service into a single
coordinated shuttle bus fleet operation resulted in customer service improvements, reduced
on-Airport vehicle miles traveled (VMT), with associated emission reductions, and stormwater
system enhancements. Rental car and bus operations began in the centralized facility in
September 2013. The remaining quick-turnaround areas, permanent taxi pool, bus, limousine
pools, and the SWSA edge buffers were completed in 2014. Consolidated bus operations continue
to reduce on-Airport VMT and associated emissions. The RCC was awarded Logan Airport’s first
Gold Certification in Leadership in Energy and Environmental Design (LEED ® ) in 2016. The status
of mitigation efforts for the RCC is provided in Chapter 9, Project Mitigation Tracking . 
 Logan Airport’s new bus fleet , comprising 22 compressed natural gas (CNG) buses and 32 clean
diesel/electric buses, has fully replaced the entire fleet of diesel rental car shuttle buses now that
the RCC is fully operational. One additional new CNG bus was put into service in 2016, increasing
the total from 21 to 22 buses. The new consolidated bus fleet has improved operational efficiency
and reduced shuttle frequency from 100 to 30 buses per hour. 
 The LEED-Silver Green Bus Depot serves as Logan Airport’s on-Airport maintenance facility for
Massport’s new clean-fuel bus fleet. By shifting the bus maintenance operations out of the
community, Massport is reducing bus traffic in East Boston and Chelsea. 
 The Martin A. Coughlin Bypass reduces commercial traffic through East Boston by providing a
direct link, along a former rail corridor, from Logan Airport’s North Service Area (NSA) to Chelsea
for Airport-related vehicle trips. 
 The Economy Parking Garage simplified and reduced on-Airport circulation by consolidating
multiple overflow parking lots throughout the Airport into a single location served by a single
shuttle route. Overall traffic circulating throughout the Airport has decreased, resulting in
significant operational and environmental benefits.

Boston-Logan International Airport 2016 EDR 
Introduction/Executive Summary 1-21 
 West Garage Parking Consolidation Project. Massport consolidated 2,050 temporary parking
spaces as an addition to the West Garage and at the existing surface lot between the Logan Office
Center and the Harborside Hyatt. The West Garage addition is located on the site of the existing Hilton
Hotel parking lot. Construction of these spaces constituted all the remaining spaces permitted under
the Logan Airport Parking Freeze. 24 The project commenced in the spring of 2016 and was completed
in late 2016. 
 Logan Airport Parking Project. As one element of its comprehensive ground transportation
strategy, Massport proposed the phased construction of 5,000 new on-Airport commercial
parking spaces at Logan Airport in two locations. The goal of the Logan Airport Parking Project is
to reduce the number of air passengers choosing more environmentally harmful drop-off/pick-up
modes, which generate up to four vehicle trips instead of two (see below for a detailed
description). The construction of additional commercial parking spaces at Logan Airport was
predicated on a regulatory change, that has been adopted by the Massachusetts Department of
Environmental Protection (MassDEP) to amend the existing Logan Airport Parking Freeze. In
response to Massport’s 2016 request to consider an amendment to the Logan Airport Parking
Freeze (to increase the commercial parking freeze limit by 5,000 spaces), MassDEP conducted a
stakeholder process, which was followed by a public process to amend the Parking Freeze
regulation. MassDEP issued the amended regulation on June 30, 2017, approving the requested
parking increase. On December 5, 2017, the U.S. Environmental Protection Agency (EPA) proposed
a rule approving the revision of the Massachusetts State Implementation Plan (SIP) incorporating
the amended Logan Airport Parking Freeze Cap. EPA approved the proposed rule on
March 6, 2018, and the rule went into effect April 5, 2018. For additional information, see
Chapter 5, Ground Access to and from Logan Airport. Massport initiated a parallel process with EEA
by filing an ENF for new parking facilities on March 31, 2017. On May 5, 2017, EEA issued its
Certificate on the ENF, establishing the Scope for the required Draft EIR. Initiation of concept
design for the parking facilities and preparation of a Draft EIR commenced in late 2017. The Draft
EIR will provide additional details on the number of spaces per location and planned construction
phasing. As outlined in the ENF, Massport has identified two potential sites for the new parking:
Economy Garage (shown as 7a in Figure 3-1 ) and Terminal E Surface Lot (shown as 7b in 
Figure 3-1 ). 
 Convenience and Filling Station/Taxi Pool/TNC Lot Relocations . Construction of the Terminal
E Modernization Project includes the relocation of the existing on-airport gas station to the
intersection of Tomahawk Drive and Jeffries Street on Massport property (Southwest Service
area). Chosen by the community-based Logan Impact Advisory Group, it provides community
benefits such as a convenience space for a local vendor, landscaping and beatification
enhancements, and traffic-congestion reductions. Another part of the design phase involved
Massport further evaluating transportation and land-uses in this area in an effort to mitigate
vehicular congestion along Tomahawk Drive associated with the growing TNC mode. As a result,
it was determined that the TNC Pool Lot would be relocated to the existing taxi pool at Porter
Street because this would minimize Tomahawk Drive traffic and congestion. Similarly, the existing
taxi pool lot will be returned to the Blue Lot between the Logan Office Center and the Hyatt
Hotel. By relocating the TNC Pool Lot and the number of TNCs servicing the Airport, greater

Boston-Logan International Airport 2016 EDR 
Introduction/Executive Summary 1-22 
operational flexibility and additional routing options are available that will allow Massport to
reduce TNC impacts along Tomahawk Drive. 
 Braintree Logan Express Acquisition. In 2015, Massport acquired the property on which the
Braintree Logan Express site is located, furthering its commitment to providing high-occupancy
vehicle (HOV) access from key regional nodes. The Braintree Logan Express service had a ridership
of 655,158 annual passenger trips in 2016, representing 36 percent of the entire Logan Express
system ridership. Approximately half of the Braintree Logan Express riders are Logan Airport
employees. The Braintree site is approximately 20 acres (14 acres of usable land area) and has
approximately 1,800 lined spaces. 
 Mid-life Rebuild of Eight Silver Line Buses. Eight Silver Line buses, connecting the Airport to
South Station, are owned by Massport and are operated by the MBTA with Massport paying
operating costs for the SL1 route. In 2016, Massport funded an approximate $6 million mid-life
rebuild of these eight buses. The mid-life rebuild will extend the useful life of each vehicle by
approximately eight years. This will allow the MBTA to maintain reliability and quality of
operations along the Silver Line today while starting the procurement process to acquire new
vehicles in the future. 
Community Park and Open Space Projects 
Massport has committed up to $15 million for the planning, construction, and maintenance of four
Airport edge buffer areas and two parks along Logan Airport’s perimeter. These buffers have now been
completed and include the Bayswater Buffer, Navy Fuel Pier Buffer, SWSA Buffer Phase 1, and the SWSA
Buffer Phase 2. These areas are located on Massport-owned property along Logan Airport’s perimeter
boundary and are intended to provide attractive landscape buffers between Airport operations and
adjacent East Boston neighborhoods. The buffer design occurs in consultation with Logan Airport’s
neighbors and other interested parties in an open community planning process. In addition to the Airport
edge buffers, Massport has been working with community leaders to provide more recreation
opportunities to local residents, such as the 3.3 miles of the East Boston Greenway Connector and Piers
Park with community boating facilities and views of downtown Boston. Over the past 10 years, Massport
has invested $50 million to develop, maintain, and secure 33 acres of green space in East Boston for
walking, playing, biking, and other forms of passive recreation. 
 Piers Park Phase II. A Request for Proposals for design of Piers Park Phase II was issued in
June 2017. Piers Park Phase II will add 4.2 acres of green space to the existing Piers Park on the
East Boston waterfront. The Phase II site is located adjacent to the Phase I site, along Marginal
Street in East Boston. The conceptual design of the Phase II site envisions a fully accessible park
with a central lawn area, basketball and volleyball courts, and bicycle and rollerblade tracks. The
park is expected to offer landscape features similar to those in the Phase I Park, including brick
paved walkways, site furniture, lighting, and plantings. A new 1,200-square foot
community/sailing center, located on the waterfront, is designed to replace the existing Sailing
Center building while providing additional meeting spaces for the community.

Boston-Logan International Airport 2016 EDR 
Introduction/Executive Summary 1-23 
 Piers Park Phase III. Piers Park Phase III is conceived as a 3.8-acre addition of greenspace to the
existing Piers Park on the East Boston waterfront. The site is located adjacent to the Phase II site,
along Marginal Street in East Boston. Piers Park Phase III is an early-stage planning concept that
Massport has proposed to external developers. Massport issued a Request for Proposals for
design of Piers Park Phase III in February 2018. Depending on responses to Massport’s Request
for Proposals, the project may be advanced by another entity. 
 Bremen Street Park and Dog Park. In September 2016, Massport officially opened the Bremen
Street Dog Park (and Bremen Street Park in 2008) on the corner of Bremen and Porter Streets in
East Boston. This recreational area allows for all types and sizes of dogs to use the 22,655-square
foot space located on the corner of Bremen and Porter Streets in East Boston. 
 The Narrow-Gauge Connector. The spring 2016 completion of the 1/3-mile long Narrow-Gauge
Connector project represents the final portion of the East Boston Greenway, which joins the East
Boston Greenway Connector, that Massport completed in 2014, with the Massachusetts
Department of Conservation and Recreation’s Constitution Beach. This project makes it possible
for pedestrians and bicyclists to travel from Jefferies Point, through Bremen Street Park and the
new East Boston Library, to Wood Island Marsh, and finally to Constitution Beach with only two
roadway crossings. There are pedestrian and bike counters along the Greenway Connector, and in
2016, there were 43,787 trips recorded. 
Planning Initiatives 
 Sustainability and Resiliency Planning. See section below titled Sustainability and Resiliency at 
Logan Airport for detailed information. 
 Runway Incursion Mitigation and Comprehensive Airfield Geometry Analysis . As FAA began
to close out its comprehensive nationwide runway safety area improvements program in 2016, its
safety focus shifted to analysis of the airfield geometry. The multi-year Runway Incursion
Mitigation (RIM) program identifies, prioritizes, and develops strategies to help airports across the
U.S. enhance airfield safety. In January 2016, Massport issued a Request for Proposals to study
airfield geometry at Logan Airport. The study commenced in December 2016 and is expected to
be completed by December 2018. As of this filing, the study has conducted an airfield geometry
and design standards analysis, aviation activity forecast, baseline safety risk assessment, and
developed a simulation model of airfield operations for baseline existing conditions. Future EDRs
and ESPRs will provide updates on this initiative and those efforts are likely to require permitting
under state or federal regulations. 
 Automated People Mover Concept. Massport is considering several potential options for an
Automated People Mover (APM). This APM could provide a robust connection between the MBTA
Airport Station and all terminals, the Southwest Service Area facilities, and other areas on-Airport.
The feasibility of constructing such a system and the operating parameters that would be
required are currently being evaluated.

Boston-Logan International Airport 2016 EDR 
Introduction/Executive Summary 1-24 
Regional Transportation 
Logan Airport and a system of 10 other commercial service, reliever, and GA airports 25 (regional airports)
anchor the New England region. Together, these 11 airports accommodate nearly all of New England’s
commercial 26 air travel demand (see Figure 1-11 ). Logan Airport serves as a major domestic O&D market
and acts as the primary international gateway for the region. Amtrak rail service, which connects Boston to
the New York/Washington D.C. metropolitan areas to the south and Portland, ME to the north, also serves
the region. 
 For the second year, the total number of
annual air passengers using New England’s
commercial service airports (Logan Airport 
plus the regional airports) represented a
record high; the total number of annual
air passengers increased by 6.4 percent,
from 48.8 million air passengers in 2015
to 51.9 million air passengers in 2016. 
 In 2015, the previous historical peak from
2005 (48 million regional air passengers)
was exceeded with 48.8 million air
passengers. Nationally, U.S. passenger
traffic exceeded pre-recession levels in
2014. It continued to show strong
growth and reached a new peak in 2016. 
 The increase in the region’s passenger
traffic is driven by continued growth at
Logan Airport and other regional
airports. Bradley International Airport,
T.F. Green Airport, Burlington
International Airport, Portland 
International Jetport, Bangor International Airport, and Portsmouth International Airport also
experienced increases in passenger traffic. 
 Of the 51.9 million passengers using New England’s commercial service airports in 2016,
69.9 percent of passengers (36.3 million) used Logan Airport compared to 68.6 percent
(33.5 million) in 2015. 27

25 Commercial Service Airports are publicly owned airports that have at least 2,500 passenger boardings each calendar year and
receive scheduled passenger service. Reliever Airports are airports designated by FAA to relieve congestion at Commercial
Service Airports and to provide improved GA access to the overall community. GA Airports are public-use airports that do not
have scheduled service or have less than 2,500 annual passenger boardings. 
26 Commercial airline service is defined as air transportation offered by air carriers for compensation or hire. In contrast, GA refers
to all aviation activity other than commercial airline and military operations. 
27 Based on airport passenger statistics from 1985 to 2016. 
Figure 1-11 New England Regional Transportation System

Boston-Logan International Airport 2016 EDR 
Introduction/Executive Summary 1-25 
 The number of passengers at T.F. Green Airport increased by 2.4 percent in 2016 compared to
2015. In 2017, with the addition of service from Frontier Airlines and Norwegian Air Shuttle,
passenger counts increased by nearly 8 percent or approximately 285,000 passengers. 
 The number of passengers at Bradley International Airport increased by 2.1 percent in 2016
compared to 2015. In 2017, the number of passengers increased by over 6 percent. This growth
marks the fifth straight year of passenger traffic growth between 2012 and 2017 (see Table 4-2 ). 
 In effect, Logan Airport, T.F. Green Airport, and Manchester-Boston Regional Airport act as a
system, with significant numbers of passengers choosing the most convenient airport in terms of
access, airfares, and available air services depending on their individual air travel needs. 28 
 Worcester Regional Airport is an important aviation resource that accommodates corporate GA
activity and commercial airline service. Massport has continued to invest in Worcester Regional
Airport by modernizing the airport to serve better the commercial airline travel demands of the
central Massachusetts region. 
▪ Together with the City of Worcester, Massport is investing $100 million over the next
10 years to revitalize and grow commercial operations at Worcester Regional Airport. As a
result of this collaboration, Worcester Regional Airport has experienced consecutive
growth since 2013 as JetBlue Airways has served nearly 500,000 passengers. 
▪ Massport completed Worcester’s Category III Instrument Landing System improvements
to elevate operational and safety conditions to a level equal to that of all other
commercial airports in New England. This project significantly improves Worcester
Regional Airport’s all-weather reliability, a long-standing impediment to greater
utilization of this airport. 
 Located in Bedford, MA, approximately 20 miles northwest of Logan Airport, Hanscom Field is
New England’s premier facility for business/corporate aviation and serves a critical role as a GA
reliever airport for Logan Airport. Hanscom Field is a full-service GA airport that accommodates a
wide variety of GA activities, including corporate aviation, private flying, commuter air services,
charters, and light cargo. 
 While the overall regional passenger activity levels have increased, aircraft operations activity
levels have declined significantly since 2000, as part of ongoing trends of larger aircraft size,
higher aircraft load factors, and reduced service in less profitable markets. Total aircraft
operations in the region declined from 1.6 million in 2000 to approximately one million in 2016. 
 The region is also served by rail service (provided by Amtrak) that connects Boston to the
New York and Washington D.C. metropolitan areas to the south and Portland, ME to the north, as
well as by an extensive highway system. In 2016, the total number of rail passengers traveling on
the Northeast Corridor was 2.6 million 29 compared to air passengers of 36.3 million at
Logan Airport.

Introduction/Executive Summary 1-26 
 System-wide Amtrak ridership was 31.3 million one-way trips in fiscal year (FY) 2016, an increase
of 400,000 over the previous year. 30 In FY 2016, the Northeast Corridor (NEC) carried 11.9 million
passengers on its Acela Express and Northeast Regional services, up 2 percent from the prior year.
Acela Express accounted for nearly 3.5 million passengers, while the Northeast Regional
accounted for 8.4 million passengers. Overall NEC ridership reached a new record in 2016,
surpassing 2015 record levels. Amtrak’s share of the Northeast total passenger market has
increased substantially since the introduction of Acela Express service in 2000. 
 Massport has continued to engage in a number of interagency planning efforts at both local and
regional levels. 
Additional information is provided in Chapter 4, Regional Transportation. 
Ground Access to and from Logan Airport 
Massport has a comprehensive strategy to diversify and enhance ground transportation options for
passengers and employees. The ground transportation strategy is designed to provide a broad range of
HOV, transit, and shared-ride options for travel to and from Logan Airport and to minimize vehicle trips,
by providing convenient transit, shuttle, bicycle, and pedestrian connections to the Airport. The strategy
also aims to provide parking on-Airport for passengers choosing to drive or with limited HOV options.
Massport’s strategy aims to limit impacts to the environment and community, while providing air
passengers and employees with many alternatives for convenient travel to and from Logan Airport. 
Massport is implementing a multi-pronged trip reduction strategy to limit impacts to the environment
and to reduce the number of private vehicles that access Logan Airport and, in particular, the associated
environmentally undesirable drop-off/pick-up modes, which generate up to four vehicle trips instead of
two. 31 Massport continues to invest in and operate Logan Airport with a goal of maintaining and
increasing the HOV mode share – the number of passengers and Airport employees arriving by transit or
other HOV/shared-ride modes. Logan Airport continues to rank at the top of U.S. airports in terms of
HOV/transit mode share, with current HOV mode share just over 30 percent. 32 Measures implemented by
Massport to increase HOV use include a blend of initiatives related to pricing (incentives and
disincentives), service availability, service quality, marketing, and traveler information. Because of the
different demographics of Logan Airport air passenger travelers, no single measure alone will accomplish
the goal to increase the HOV mode share.

results/ . 
31 Drop-off/pick-up modes can include private vehicles, taxis, and black car services. For example, if an air passenger is dropped
off when s/he departs on an air trip and is picked-up upon their return, that single air passenger generates a total of four
ground-access trips: two for the drop-off trip (one inbound to Logan Airport, one outbound from Logan Airport) and two for
the pick-up trip (one inbound to Logan Airport, one outbound from Logan Airport). The air passenger may be dropped off and
picked up in a private vehicle or in a taxi, TNCs, or black car that may not carry a passenger during all segments of travel to and
from Logan Airport. 
32 According to the 2016 Logan Airport Air Passenger Ground-Access Survey , 30.5 percent of air passengers accessing
Logan Airport used HOV modes of travel.

Boston-Logan International Airport 2016 EDR 
Introduction/Executive Summary 1-27 
Key findings on ground access conditions and activity levels include: 
 Since 2000, the highest average weekday vehicle miles traveled (VMT) estimated at Logan Airport
was in 2007. Although 2007 air passenger levels have grown by 29.1 percent, the 2016 daily VMT
estimates remain about 4.4 percent lower than 2007 levels. 
 Current annual average daily traffic (AADT) and annual average weekday daily traffic (AWDT)
values are approximately 5.4 percent higher than in 2015, which was lower than the approximately
8.5 percent growth in air passenger levels. VMT increased by approximately 4.8 percent from 2015
to 2016. Although daily traffic volumes on the airport roadway system have been increasing, it is
important to contrast this increase with historical air passenger growth. Airport gateway 33 traffic
volume is growing at a significantly lower rate than air passenger growth, reflecting Massport’s
decade long commitment to improving and supporting HOV access to the Airport. 
 Pursuant to Massachusetts state law, An Act Regulating Transportation Network Companies (Bill
H.4570), and Massport Rules for Safe and Efficient operation of TNCs at Logan Airport, beginning
in February 2017, in cooperation with state regulators, Massport began allowing TNCs to pick-up
arriving passengers via a TNC Pool Lot. 34 This is a service that is being tracked for reporting in
2017. 
 Beginning with the 2017 ESPR , Massport will introduce a new definition for HOV that takes into
account vehicle occupancies of taxi, livery (black car limousine), and TNC modes. 35 Under the
current system, Massport counts all taxis as non-HOV and all black car limousines as HOV,
regardless of the number of passengers transported. Massport is currently also classifying TNCs
as non-HOV, regardless of the number of passengers transported. Beginning with the 2017 ESPR ,
Massport will use a new HOV definition, where vehicle occupancies of taxis, livery services, and
TNCs that exceed one air passenger per vehicle will be defined as HOV. With this new definition,
Massport has committed to a goal of 35.5 percent HOV by 2022 and 40 percent by 2027. 
 Massport continues to offer a pilot program, Back Bay Logan Express, which provides frequent, 
direct, express bus service from the City of Boston. This service has been valuable in providing an
alternative to air passengers and employees who were impacted by the temporary, two-year 
Government Center Station closure (a key connection to the Blue Line and Logan Airport), and it
provides a new transit alternative from the Back Bay/Hynes Convention Center area to the Airport.
Ridership in 2016 for the Back Bay Logan Express totaled 216,329 passengers (compared to
290,796 passengers in 2015), an average of about 600 riders per day. The ridership decreased by
about 33 percent for the second half of the year (July through December), which may be
attributed to the reopening of the MBTA Government Center Station. 
 Eight Silver Line buses, connecting the Airport to South Station, are owned by Massport and are 
operated by the MBTA with Massport paying operating costs for the Silver Line SL1 route. In 2016,
Massport funded an approximate $6 million mid-life rebuild of these eight buses. The mid-life

35 A transportation network company (TNC) is a company that uses an online-enabled platform to connect paying passengers
with drivers who provide transportation from their own non-commercial vehicles. TNCs have emerged as a new option mode of
transportation with automobile drop-off and pick-up at Logan terminals. The 2016 Logan Airport Air Passenger Ground-Access
Survey and future documents will analyze trends associated with TNCs.

Boston-Logan International Airport 2016 EDR 
Introduction/Executive Summary 1-28 
rebuild will extend the useful life of each vehicle by approximately eight years. This will allow the
MBTA to maintain reliability and quality of operations along the Silver Line today while starting
the procurement process to acquire new vehicles in the future. 
 Total on-Airport commercial parking exits declined by 0.2 percent in 2016. Slower growth in
overall parking may be a result of customers choosing alternate modes due to the known issue of
constrained parking on the Airport and, especially for residents originating within Route 128, the
emergence of TNCs as a reliable and cost-effective alternative. 
 The inadequate supply of parking causes air passengers to circulate on Airport roadways to find
parking. In overflow conditions, cars are diverted or moved to non-garage parking areas,
including overflow lots, some of which are located off-Airport. Not only does parking demand
activity above capacity lower customer service levels, it also increases on-Airport roadway vehicle
emissions related to circulating traffic. Diversions 36 and valeting 37 have become a regular
occurrence at Logan Airport. Massport continued to be in full compliance with the Logan Airport
Parking Freeze in 2016. 
 Massport continues to manage parking supply, pricing, and operations to promote the use of
transit/HOV/shared-ride options and to reduce the amount of diversions/valeting. Massport
strives to meet these goals without increasing the number of drop-off/pick-up trips experienced
due to a constrained parking supply. These policies supported growth since 2015 in transit and
shared-ride alternatives, especially for Logan Express park-and-ride and private bus services. 
Additional information is provided in Chapter 5, Ground Access to and from Logan Airport. 
Noise Abatement 
Massport strives to minimize the noise effects of Logan Airport operations on its neighbors through a
variety of noise abatement programs, procedures, and other tools. At Logan Airport, Massport
implements one of the oldest and most extensive noise abatement programs of any airport in the nation.
Massport’s comprehensive noise abatement program includes a dedicated Noise Abatement Office; a
state-of-the-art Noise and Operations Monitoring system; residential and school sound insulation
programs; time and runway restrictions for noisier aircraft; ground run-up procedures; and flight tracks
designed to optimize over-water operations (especially during nighttime hours 38 ). 
Since Logan Airport’s peak operations year in 1998, the number of daily aircraft operations have declined
by 23 percent (from 1,390 operations per day in 1998 to 1,069 operations per day in 2016 39 ) due to the
industry-wide trend of increasing passenger loads. In 2016, jet operations made up 86 percent of
operations compared to 55 percent in 1998, reflecting a change in the aircraft fleet mix. Passenger
volumes continue to increase at a higher rate than aircraft operations. In 2016, the overall number of air
passengers was up by 36.7 percent compared to 1998, and 8.5 percent since 2015. This trend reflects an

37 Valeting is an operational practice where attendants park vehicles for travelers, typically due to the desire of maximizing the
number of vehicles parked at a facility or on-Airport. 
38 Nighttime hours are defined as 10:00 PM to 7:00 AM.

increase in the use of larger aircraft in the fleet, airline consolidation, and increased aircraft load factors 40 
on the part of airlines. 
Noise conditions for 2016 were assessed primarily through computer modeling, supplemented by the
analysis of measured noise levels from Logan Airport’s noise monitoring system. This 2016 EDR marks the
transition from FAA’s legacy analysis software, the Integrated Noise Model (INM), to its next-generation
software, the Aviation Environmental Design Tool (AEDT). Massport developed a suite of customized
adjustments for use with INM, necessary for accurate modeling of the unique Logan Airport environment,
and has been working with FAA since 2015 to implement equivalent methods in AEDT. FAA has
responded to Massport's request. FAA did not approve two adjustments: over-water noise propagation
and hill effects. FAA did approve the use of 2016 weather data and Logan Airport-specific aircraft stage
length adjustments. Consistent with previous practice, Massport presents AEDT modeling results as the
primary model in this 2016 EDR. INM results are provided for comparison only for 2016 and future filings
will present only AEDT results. 
Research efforts that address potential improvements in AEDT modeling are underway for terrain
improvements and were recently concluded for acoustically reflective surfaces. The results of these
studies, if and when they are implemented in AEDT, will add capabilities previously addressed by Logan
Airport’s over-water and hill effect adjustments. 
Operations, Fleet Mix, and Runway Use 
 Annual aircraft operations in 2016 increased from 372,930 operations in 2015 to 391,222 in 2016
(a 4.9-percent increase). Compared with the 1998 peak of 507,449 operations, 2016 had
22.9 percent fewer operations. At the same time, passenger volumes are at their highest,
increasing from 33,449,580 passengers in 2015 to 36,288,042 in 2016 (an increase of 8.5 percent). 
 Overall commercial traffic increased from 344,764 to 360,400 (a 4.2-percent increase) compared
to 2015. In 2016 there was a continued shift of operations away from the smaller Regional Jet (RJ)
aircraft to larger air carrier aircraft on many routes, increasing the number of passengers carried
per operation. 
 Among commercial jet operations at Logan Airport, 18 percent were by aircraft that already
satisfy the newly enacted Stage 5 limits. 41 When considering all types of aircraft, 97 percent met
the Stage 4 noise limits. Of the remaining 3 percent, only three operations in 2016 were
performed by aircraft retrofitted to satisfy Stage 3 standards; all other commercial jet operations
were performed by aircraft originally certificated to Stage 3 or better. 42 As of January 1, 2016, all
Stage 2 aircraft are prohibited by FAA from operating within the contiguous United States, and
there were no Stage 2 operations at Logan Airport for 2016. 
–––––––––––––––– 
40 Load Factor refers to the number of passengers as a percentage of total seats operated at the airport. 
41 In October 2017, FAA established deadlines for Stage 5 certification for new aircraft. Large aircraft (over 121,000 lbs maximum
takeoff weight) must satisfy Stage 5 limits if entering service after December 31, 2017, and smaller aircraft entering service after
December 31, 2020 must satisfy these limits. 
42 Jet aircraft currently operating at Logan Airport are categorized by FAA into the two groups: Stage 3 and Stage 4. The
designation refers to a noise classification specified in Federal Aviation Regulation (FAR) Part 36 that sets noise emission
standards based on an aircraft’s maximum certificated weight. Generally, the heavier the aircraft, the more noise it is permitted
to make within the limits established by FAR Part 36.

Boston-Logan International Airport 2016 EDR 
Introduction/Executive Summary 1-30 
 The 2016 Flight Track Monitoring reports in Appendix H, Noise Abatement, show that 99 percent
of shoreline crossings (locations where aircraft which have departed over the water pass back
over land) were by aircraft flying above 6,000 feet, the same percentage as 2015. This results in
lower day-night average sound level (DNL) exposure levels to communities under those flight
paths. 
Noise Levels and Population 
 Differences between measured and modeled values have narrowed in recent years as both the
noise monitoring and modeling processes have been refined. For 2016, these differences have
increased moderately with the change to AEDT for modeling. 
 The 2016 contours are smaller in area coverage than the 2000 contours in most areas as a result
of quieter engines and fewer flights, although the contour has expanded in portions of Eagle Hill
in East Boston. 
Changes in operations at Logan Airport influencing noise exposure for 2016 versus 2015 are discussed
below and shown in Figure 1-12 . 
Figure 1-12 Reason for increase in Number of People Exposed to DNL Values
Greater than or Equal to 65 dB (2015 INM to 2016 INM) 
Note: When comparing the 2015 INM contour to the 2016 INM contour, there is an increase in noise exposed population.
However, when comparing 2015 INM (the official 2015 model) and 2016 AEDT (the official 2016 model) there is a decrease
in the noise exposed population. 
 Runway use changes from 2015 to 2016 were the largest factor influencing noise exposure in
2016. The one-month closure of Runway 4L-22R for resurfacing caused air traffic to shift to
Runway 15R-33L and Runway 9-27, and these changes in runway use are reflected in the contour
changes.

Boston-Logan International Airport 2016 EDR 
Introduction/Executive Summary 1-31 
▪ East Boston is affected by start-of-takeoff roll (SOTR) noise from Runway 15R and departure
overflights from Runway 33L, both of which had increases in departures; 
▪ Increases in departures from Runway 9 and Runway 27 had the effect of expanding the noise
contour over Winthrop near Deer Island; and 
▪ Other changes in the contour were in nonresidential or offshore areas, but these were similarly
affected by runway use changes. 
 An additional factor influencing noise contour changes in 2016 was an increase in nighttime
operations, from 50,786 in 2015 to 55,499 in 2016. Due to the 10-dB penalty applied to modeled
nighttime operations, these operations have a disproportionate effect on the contour. 
 Noise exposed population in 2016 was below the peak levels reached in 1990 and was less than in
the year 2000 when 17,745 people were exposed to DNL levels greater than or equal to DNL
65 dB. Population exposed to these noise levels for 2016 was calculated to be 16,985 using the
legacy INM model, and 7,450 using the next-generation AEDT model. 
 Massport is a national leader in sound insulation mitigation. To date, in the vicinity of
Logan Airport, Massport has provided sound insulation for a total of 11,515 residential units, and
will continue to seek funding for sound insulation for properties that are eligible and whose
owners have chosen to participate. 
 Almost all residences exposed
to levels greater than or equal
to DNL 65 dB in 2016 have been
eligible in the past to participate
in Massport’s residential sound
insulation program (RSIP). 
 In 2016, Massport received
38,045 noise complaints from
83 communities, compared to
17,685 in 2015 from 84
communities. It is important to 
note that the number of individual complainants rose from 1,903 in 2015 to 2,260 in 2016. The
increase in complaints continues to be primarily related to the FAA’s RNAV departure procedures,
which concentrate flight tracks along narrower corridors. As has been Massport’s practice, all
complaints were forwarded to FAA. 
FAA Reporting and Update 
 In 2015, FAA required the use of its AEDT as a replacement for its legacy tool, the INM, for noise
analyses requiring FAA approval. Prior to this, FAA had approved adjustments specific to Logan
Airport to be used with INM, and Massport has been working with FAA to develop analogous
adjustments to implement in AEDT. Massport chose to continue use of the INM for the 2015 EDR 
while these discussions progressed, since FAA approval is not required for the EDR. In August
2017, FAA provided formal concurrence for some proposed adjustments but declined to concur
with others. The memoranda related to this decision are included at the end of this chapter and in

Boston-Logan International Airport 2016 EDR 
Introduction/Executive Summary 1-32 
Appendix H, Noise Abatement . Further details are provided below in the section on AEDT
modeling. 
 On October 7, 2016, Massport and FAA signed a Memorandum of Understanding (MOU) 43 to
frame the process for analyzing opportunities to reduce noise through changes or amendments
to Performance Based Navigation (PBN), including RNAV. Massport has been working with the
FAA and others to develop test projects that are designed to help address the concentration of
noise from PBN. This cooperation is a first-in-the-nation project between FAA and an airport
operator to better understand the implications of PBN and evaluate strategies to address
community concerns. 
 The FAA’s ROD (August 2002) approving construction of the unidirectional Runway 14-32
required that FAA, Massport, and the Logan Airport Community Advisory Committee (CAC) to
jointly undertake a study to enhance existing and/or develop new noise abatement measures to
further reduce noise impacts. The primary focus of the Boston-Logan Airport Noise Study (BLANS)
was to determine viable ways to reduce noise from aircraft operations to and from Logan Airport
without diminishing airport safety and efficiency. 44 The RNAV departure portions of Phase 1 of
the project, first implemented in 2010, continued to be used in 2016. 
▪ During Phase 2 of the BLANS, the Logan Airport CAC voted to abandon the Preferential
Runway Advisory System (PRAS) because it had not achieved the intended noise
abatement. Although PRAS is not an active program, Massport continues to report on
runway use relative to PRAS goals. 
▪ Phase 3 of BLANS is a series of tests of a potential Runway Use Program, which began in
November 2014 and ended in November 2015. 
▪ The BLANS project ended in 2016 without the development of a new Runway Use
Program. A final report for the program was issued in March 2017. 45 
 In May 2015, FAA announced that it had begun a nationwide study to re-evaluate the method for
measuring effects of aircraft noise (DNL). 46 This is a multi-year study to update the scientific
evidence on the relationship between aircraft noise exposure and its effects on communities
around airports. FAA has been evaluating survey and noise data from 20 airports across the
country and will then analyze the results to determine whether to update its methods for
determining exposure to noise. Results of this study are expected by summer 2018. Future EDRs
and ESPRs will provide updates, as available. 
As shown in Figure 1-13 , the 2016 DNL 65 dB contour is smaller than previous years including the 1998
DNL contour and 1990 DNL contour. Additional information is provided in Chapter 6, Noise Abatement .

Introduction/Executive Summary 1-34 
Air Quality/Emissions Reduction 
As reported in previous EDRs, total air emissions from all sources associated with Logan Airport are
considerably less than they were a decade ago. This long-term downward trend is consistent with
Massport’s longstanding objective to accommodate the demands of increasing passenger and cargo
activity levels with reduced emissions. When compared to 2015, the changes in air emissions in 2016 are
slightly up. The changes are associated with the upturn in aircraft operations. Massport is also committed
to reducing VMT and associated emissions on Massport-controlled ground transport facilities (such as
roadways and curbsides, parking facilities, and vehicle staging areas), as well as reducing VMT by airport
users traveling to and from the Airport. Chapter 5, Ground Access to and from Logan Airport provides
detailed information on Massport’s ground access and parking management strategy. 
Each year, Massport models the changes in air emissions for Airport-related activities. For the purposes of
this assessment, the air quality modeled results are also a function of other important model input
parameters including: 
 Aircraft fleet mix characteristics; 
 Airfield taxi/delay times; 
 Ground service equipment (GSE) usage, including aircraft auxiliary power units (APUs); 
 Motor vehicle traffic volumes; and 
 Stationary source operations such as the Central Heating and Cooling Plant, snow melters, and
emergency generators. 
The following is a synopsis of these model inputs and updates for this 2016 EDR : 
 As of 2015, FAA requires aircraft-related assessments to be conducted using its new simulation
tool for noise and air emissions, AEDT, for National Environmental Policy Act (NEPA) projects and
soundproofing eligibility. For 2016, air quality modeling was performed with the latest version of
FAA’s AEDT to compute emissions from Logan Airport specific aircraft, APUs, and GSE. Modeling
was also completed using the legacy model, FAA’s Emissions and Dispersion Modeling System
(EDMS), for comparison purposes. Massport will use AEDT for upcoming EDRs and ESPRs. 
 Key inputs into the air emissions inventory include aircraft operations and average aircraft
taxi/delay times. Aircraft operations increased 4.9 percent in 2016, from 195,611 landing and take
offs (LTOs) 47 in 2016 compared to 186,465 LTOs in 2015. Average aircraft taxi/delay times
decreased by about 30 seconds (25.3 minutes in 2016 versus 25.9 minutes in 2015). Although
there was an increase in LTOs in 2016, aircraft operations and taxi times remained well below
2000 historic peak levels. 48 There were 243,998 LTOs in 2000 and the corresponding aircraft taxi
times were about 27 minutes. 
–––––––––––––––– 
47 An LTO is defined as one landing/take-off cycle; it includes both the arrival and the departure. In Chapter 2, Activity Levels, the
operation count is defined differently and counts one operation as either an arrival (landing) or a departure (take-off). Thus,
there are 391,222 operations in 2016 (195,611 LTOs) and 372,930 operations in 2015 (186,465 LTOs). 
48 See Chapter 2, Activity Levels for additional information on aircraft operations in 2016 and long-term trends.

Boston-Logan International Airport 2016 EDR 
Introduction/Executive Summary 1-35 
 GSE emission factors in the AEDT database (derived from EPA’s OFFROAD model) decreased in
2016 when compared to 2015 as this model also takes into account fleet modernization from year
to year. Model input data are based on an updated on-site GSE time-in-mode survey conducted
in June 2017 at the Airport. These data are combined with the most recent information regarding
GSE fuel use (e.g., gasoline, diesel, CNG, liquid petroleum gas [LPG], and electric) from the Logan
Airport Vehicle Aerodrome Permit Application documentation. 49 Compared to 2015, 2016 APU
operating times increased by approximately 7.7 and 5.8 minutes for narrow body air carriers and
large commuter aircraft, respectively. This change is primarily attributed to the updated 2017
time-in-mode survey, which provides a representation of actual APU operating times. The 2017
GSE time-in-mode survey can be found in Appendix I, Air Quality/Emissions Reduction. 
 Motor vehicle emission factors were obtained from the newest version of the EPA’s Motor Vehicle
Emission Simulator model (MOVES2014a) and were combined with the MassDEP-recommended
motor vehicle fleet mix data, operating conditions, and other Massachusetts-specific input
parameters. 
 Another important model input parameter is on-Airport VMT, which increased by approximately
4.8 percent in 2016 compared to 2015. The increase in VMT is largely associated with the
8.5-percent increase in passengers from 33.4 million in 2015 to 36.3 million in 2016 (see
Chapter 5, Ground Access to and from Logan Airport for additional information). 
 Natural gas usage by stationary sources (such as boilers and snow melters) decreased by
7.3 percent in 2016, when compared to 2015 (from 463 million cubic feet in 2015 to 429 million
cubic feet in 2016). Diesel fuel usage by other snow melters also decreased in 2016 (from
381,581 gallons in 2015 to 90,850 gallons in 2016). These changes were largely attributable to a
milder winter in 2016 compared to 2015. 
 Fuel throughput of Jet A and gasoline increased by 21.6 percent and 4.9 percent, respectively, in
2016, when compared to 2015. These changes were mostly due to the increase in the number of
aircraft operations and motor vehicles trips/VMT in 2016. 
Based upon these model input parameters, the modeling results of the 2016 air emissions inventory for
Logan Airport are summarized below. As shown in Table 1-4 , AEDT computes somewhat higher
aircraft-related emissions of volatile organic compounds (VOCs), oxides of nitrogen (NOX), and carbon
monoxide (CO) in comparison to EDMS model results. However, for particulate matter (PM)10/2.5 estimates,
the results are reversed with EDMS producing more modeled emissions than AEDT. 
–––––––––––––––– 
49 All vehicles and equipment (including GSE) that operate on the airfield must obtain a Logan Airport Vehicle Aerodrome Permit.
The application form for this permit was modified in 2007 to request the fuel-type information (e.g., gasoline, diesel, CNG, LPG,
and electric).

 Total modeled emissions of VOCs increased by 7.7 percent in 2016 to 1,280 kilograms (kg)/day,
compared to 1,188 kg/day in 2015, which is still well below 1990 and 2000 levels. The increase in
VOC emissions is primarily influenced by the increase in emissions from other sources, which
include stationary and fueling sources and an increase in aircraft-related VOC emissions due to
modeling differences between EDMS and AEDT. 
 Total modeled NOx emissions increased by 24.4 percent in 2016 to 5,300 kg/day, compared to
4,262 kg/day in 2015. The increase in 2016 is still well below 1990 and 2000 levels. The increase in
NOx emissions is influenced by the increase in aircraft operations in 2016 and largely due to
modeling differences between EDMS and AEDT. 
 Total modeled CO emissions increased by 1.5 percent in 2016 to 7,350 kg/day, compared to
7,243 kg/day in 2015; emissions in 2016 were still well below 1990 and 2000 levels. The change in
CO emissions is influenced by the increase in aircraft operations; however, this was offset by a
decrease in motor vehicle emissions factors in 2016. 
 Total modeled PM10/PM2.5 emissions decreased by 2.0 percent in 2016 to 96 kg/day, compared to
98 kg/day in 2015. The decrease in PM10/PM2.5 emissions is primarily influenced by model
differences for aircraft emissions in AEDT. 
 For nine consecutive years, Massport has voluntarily prepared a greenhouse gas (GHG) emissions
inventory for the Logan Airport EDR. In 2016, total GHG emissions grew by approximately 2.8
percent. As reported in past year’s EDRs, Logan Airport-related GHG emissions in 2016 comprised
less than 1 percent of statewide totals. 
 In response to the March 9, 2018 Secretary’s Certificate on the 2016 EDR Notice of Project Change ,
Massport has augmented its GHG reporting to show normalized GHG emissions and building
energy use data (see Chapter 7, Air Quality/Emissions Reduction ). Normalizing the data shows that
Logan Airport is operating more efficiently over time, serving more passengers in larger building
footprint with less energy.

Boston-Logan International Airport 2016 EDR 
Introduction/Executive Summary 1-37 
▪ GHG emissions per passenger (Scopes 1 and 2) have decreased by over 34 percent from 2007
to 2016. 
▪ Logan Airport’s energy use intensity, which is a measure of building-only energy consumption
per square foot, has decreased by over 23 percent from 2007 to 2016. 
▪ Building GHG emissions per square foot has decreased by over 43 percent from 2007 to 2016. 
Additional information is provided in Chapter 7, Air Quality/Emissions Reduction. 
Water Quality/Environmental Compliance and Management 
Massport’s approach to environmental management and compliance is a key component of its
commitment to sustainability and responsible stewardship at Logan Airport (refer to the following section
of this chapter for details). Through monitoring and documentation, environmental performance is
assessed, allowing policies and programs to be developed, implemented, evaluated, and continuously
improved. 
Massport is responsible for ensuring compliance with applicable state and federal environmental laws and
regulations. Massport promotes appropriate environmental practices through pollution prevention and
remediation measures. Massport also works closely with Airport tenants and Airport operations staff in an
effort to improve compliance. The following summarizes the key water quality and compliance findings
for 2016. 
 The most recent International Organization for Standardization (ISO) 14001 Environmental
Management System certification audit took place in June 2014, and a certificate was issued in
July 2014. This certificate is valid through July 2017. Massport holds regular meetings to adhere to
regulatory requirements and improve environmental performance beyond compliance. 
 Massport’s Stormwater Pollution Prevention Plan (SWPPP) addresses general stormwater
pollutants and also addresses deicing and anti-icing chemicals, potential bacteria, fuel and oil,
and other potential sources of stormwater pollutants. 50 
 In 2016, approximately 98.6 percent of stormwater samples were in compliance with standards
(see Table J-15 in Appendix J, Water Quality/Environmental Compliance and Management for
more details). Due to the large size of the drainage areas and relatively low concentration of
pollutants, it is not always possible to trace exceedances to specific events. Where a known event
such as a spill is reported, Massport routinely checks the drainage system for impacts from the
event and takes corrective actions if necessary. 
 Out of 204 samples (including: oil and grease, total suspended solids (TSS), and pH at North,
West, Porter Street, and Maverick Street Outfalls), 201 were at or below National Pollutant
Discharge Elimination System (NPDES) permit limits. 
–––––––––––––––– 
50 The 2016 Annual Certificates of Compliance were submitted to EPA and MassDEP on December 21, 2016, for Massport and the
co-permittees.

Boston-Logan International Airport 2016 EDR 
Introduction/Executive Summary 1-38 
▪ One outfall sample, out of a total of 23 samples, at the Maverick Street Outfall exceeded the
regulatory limit of the NPDES Permit for TSS. The TSS exceedance at the Maverick Street
Outfall was reported in November 2016. 
▪ One outfall sample, out of a total of 11 samples, at the Maverick Street Outfall and one
sample, out of a total of 11 samples, at the North Outfall was measured outside of the
regulatory limits of the NPDES permit for pH. The pH exceedance at the Maverick Street
Outfall was reported in March 2016 and the pH exceedance at the North Outfall was reported
in April 2016, as required. 
 In 2016, there were 14 oil and hazardous material spills that required reporting to MassDEP, five
of which involved the storm drainage system. 51 All spills were adequately addressed with no
adverse impacts to water quality. 
 In accordance with the Massachusetts Contingency Plan (MCP), Massport continues to assess,
remediate, and bring to regulatory closure areas of subsurface contamination. Massport is
working towards achieving regulatory closure of the remaining Logan Airport MCP sites
associated with known releases, as well as addressing sites encountered during construction. (see 
Table 8-4 in Chapter 8, Water Quality/Environmental Compliance and Management for more
information about updates and progress made for all MCP sites.) 
Chapter 8, Water Quality/Environmental Compliance and Management provides additional information .

Introduction/Executive Summary 1-39 
Sustainability and Resiliency at Logan Airport 
Massport is committed to a robust
sustainability program.
Sustainability has redefined the
values and criteria for measuring
organizational success by using a
"triple bottom line" approach that
considers economic, ecological,
and social well-being. Applying
this approach to decision-making
is a practical way to optimize
economic, environmental, and
social capital. Massport is taking a
broad view of sustainability that
builds upon the triple bottom line
concept, and considers the
airport-specific context.
Consistent with the Airports Council International - North America’s (ACI-NA) definition of Airport
Sustainability 52 (see Figure 1-14 ), Massport is focused on a holistic approach to managing Logan Airport
to ensure Economic viability, Operational efficiency, Natural resource conservation, and Social
responsibility (EONS). Massport is committed to implementing environmentally sustainable practices
Airport- and Authority-wide, and continues to make progress on a range of initiatives. The following
sections summarize many of the long-term and multifaceted sustainability initiatives undertaken by
Massport, which individual chapters of this 2016 EDR more fully describe, where appropriate. Figure 1-15 
highlights some of Massport’s recent sustainability initiatives.

Introduction/Executive Summary 1-40 
Logan Airport Sustainability Management Plan (SMP) 
Massport is committed to reducing local environmental impacts without sacrificing service level;
Massport’s robust sustainability program is indicative of this commitment. In 2013, Massport was awarded
a grant by FAA to prepare a SMP for Logan Airport. The Logan Airport SMP planning effort began in
May 2013 and was completed in April 2015. The Logan Airport SMP takes a broad view of sustainability
including economic vitality, operational efficiency, natural resource conservation, and social responsibility
considerations. The Logan Airport SMP is intended to promote and integrate sustainability Airport-wide
and to coordinate on-going sustainability efforts across Massport. The Logan Airport SMP developed a
framework and implementation plan, with metrics and targets, designed to track progress over time.
Massport is currently advancing a series of short-term initiatives to help reach its goals (see Table 1-5 ) in
the areas of energy and greenhouse gas emissions; community, employee, and passenger well-being;
resiliency; materials, waste management, and recycling; and water conservation. The Logan Airport SMP is
available online at: https://www.massport.com/massport/business/capital-
improvements/sustainability/sustainability-management/. 
The Logan Airport Annual Sustainability Report, first published in April 2016, provides a progress summary
of sustainability efforts at Logan Airport based on Massport’s sustainability goals and targets established
in the Logan Airport SMP. A copy of the Annual Sustainability Report can be found at: 
http://www.massport.com/media/2363/logan-annual-sustainability-report-2016.pdf . 
Logan Airport Sustainability Goals 
As part of the Logan Airport SMP, Massport set goals to improve Logan Airport’s performance in
ten sustainability categories: (1) energy and GHG emissions; (2) water conservation; (3) community,
employee, and passenger well-being; (4) materials, waste management, and recycling; (5) resiliency; (6)
noise abatement; (7) air quality improvement; (8) ground access and connectivity; (9) water
quality/stormwater; and (10) natural resources. Table 1-5 describes each goal, as the Logan Airport SMP 
defines them. Massport reports its progress towards achieving each goal, including changes in related
performance, in sustainability reports. Massport released its first sustainability report in 2016. Since the
publication of the 2015 Logan Airport SMP , Massport has continued expanding its sustainability initiatives,
which an increased focus on implementing resliency measures to protect Maritime and Logan Airport
operations, cirital infrastructure, and workforce. The lastest Annual Sustainability and Resiliency Report
highlights Massport’s progress towards improving sustainability and enhancing resiliency at its facilities
and is available on Massport’s website at: http://www.massport.com/massport/business/capital-

Introduction/Executive Summary 1-42 
Sustainability in Planning, Design, and Construction 
The following sections outline Massport’s sustainability achievements in the planning, design, and
construction of its projects. 
Leadership in Energy and Environmental Design (LEED ® )-Certified Facilities at
Logan Airport 
The United States Green Building Council’s (USGBC) LEED rating system is the most widely recognized
third-party green building certification system in North America. Massport is striving to achieve
LEED certification for all new and substantial renovation building projects over 20,000 square feet. Most
recently, in 2017, the Terminal E New Large Aircraft Wing (Terminal E Renovation and Enhancements
Project) received LEED Gold certification for Commercial Interiors. Other recent examples of LEED-certified
buildings at Logan Airport are the new RCC and the Green Bus Depot (see Figure 1-16 and Table 1-6 ).
The new RCC in the SWSA began construction in 2010 and was completed in 2013. Massport is very proud
that the RCC obtained Logan Airport’s first LEED Gold certification in 2015. The LEED-Silver Green Bus
Depot shifted bus maintenance operations on-Airport from an off-Airport location, which reduced bus
trips and unnecessary emissions on congested neighborhood roadways. Further details are available in
Chapter 3, Airport Planning. 
Sustainable Design Standards and Guidelines and LEED Certification 
For smaller building projects and non-building projects, Massport uses its Sustainable Design Standards
and Guidelines (SDSG) to incorporate sustainability. The SDSG, revised and reissued in March 2011,
provides a framework for sustainable design and construction for both new construction and
rehabilitation projects. The SDSG applies to a wide range of project-specific criteria, such as site design,
project materials, energy management and efficiency, air emissions, water management quality and
efficiency, indoor air quality, and occupant comfort. Massport has used the new standards to guide over
$200 million in capital projects Authority-wide between fiscal years 2010 to 2013, including over
$30 million for maritime projects. In addition to SDSG, Massport strives to attain LEED certification for
eligible projects. In 2014, the Green Bus Depot was certified as LEED Silver, and in 2015, the RCC was
certified as LEED Gold.

Introduction/Executive Summary 1-44 
Climate Change and Resiliency Planning 
As the Boston area will continue to experience increased temperatures, more frequent extreme weather
events, and higher sea level due to climate change, 53 Massport understands the importance of preparing
for impacts in order to protect and enhance its critical infrastructure, operational assets, and workforce.
Through robust planning and regional collaboration, Massport strives to continue its leadership role in
resiliency planning among port authorities, the airport industry, and the Boston region. 
At the end of 2013, Massport initiated a Disaster and Infrastructure Resiliency Planning (DIRP) Study for
Logan Airport, the Port of Boston, and Massport’s waterfront assets in South and East Boston. The DIRP
Study includes a hazard analysis, modeling sea-level rise and storm surge, and projections of temperature,
precipitation, and anticipated increases in extreme weather events. The DIRP Study provides
recommendations regarding short-term strategies to make Massport’s facilities more resilient to the likely
effects of climate change. In 2014, the study was completed and implementation of adaptation initiatives
began in late 2014. 
In addition to the DIRP Study and its related initiatives, Massport has completed an Authority-wide risk
assessment, as part of its strategic planning initiative; issued a Floodproofing Design Guide; and has
developed a resilience framework to provide consistent metrics for short- and long-term planning and
protection of its critical facilities and infrastructure. Beyond physical resiliency, Massport is also focused on
incorporating social and economic resilience into its long-term operational and capital planning.
Massport’s Floodproofing Design Guide was published in November 2014 and updated in April 2016. 
Operational aspects of resiliency strategy include the development of Flood Operations Plans for Logan
Airport and Massport maritime facilities. These plans were introduced in 2015 and included the planned
deployment of temporary flood barriers to protect up to 12 locations of critical infrastructure in the event
of severe weather. Additional locations have been permanently enhanced to prevent flooding. The flood
operations plans are evaluated annually to enhance their effectiveness and to adapt to evolving
requirements and past experiences.

Introduction/Executive Summary 1-45 
Tabletop planning exercises simulating a hurricane scenario and cross-functional workshops have been
conducted to further refine plans and train staff. Finally, the design flood elevation that resulted from the
original DIRP study in 2015 was updated as a result of enhanced storm modeling that was made available
to Massport through MassDOT. Adjustments to the prioritized resiliency recommendations were made to
accommodate the revised flood elevation. 
Massport reports on progress towards resiliency goals in its Logan Airport Annual Sustainability Reports.

Logan Airport Environmental Review Process 
This 2016 EDR is part of a well-established, state-level environmental review process that assesses
Logan Airport’s cumulative environmental impacts. The process provides a context against which
individual projects at Logan Airport meeting state and federal environmental review thresholds are
evaluated on a project-specific basis. The Airport-wide and project-specific environmental review
processes are described below. 
Historical Context for the Logan Airport EDR/ESPR 
In 1979, the Secretary of EEA issued a Certificate requiring Massport to define, evaluate, and disclose
every three years the impact of long-term growth at the Airport through a Generic Environmental Impact
Report (GEIR). The Certificate also required interim Annual Updates to provide data on conditions for the
years between GEIRs. The GEIR evolved into an effective planning tool for Massport and provided
projections of environmental conditions so that the cumulative effects of individual projects could be
evaluated within a broader context. 
EEA eliminated GEIRs following the 1998 revisions to its MEPA regulations. However, the Secretary’s
Certificate on the 1997 Annual Update 54 proposed a revised environmental review process for
Logan Airport resulting in Massport’s preparation of subsequent EDRs/ESPRs. The more comprehensive
ESPRs provide a long-range analysis of projected operations, passengers, and cumulative impacts, while
EDRs are prepared annually to provide a review of environmental conditions for the reporting year
compared to the previous year. The EDR/ESPR process was developed to allow individual projects at
Logan Airport to be considered and analyzed in the broader, Airport-wide context. As stated in the
introduction to the 1999 ESPR , “while the Logan ESPR and EDRs provide the broad planning context for
projects proposed for Logan Airport and future planning concepts under consideration by Massport, no
specific projects can be built solely on the basis of inclusion and discussion in the 1999 ESPR.” It continues
to state that projects that meet MEPA or NEPA review thresholds must undergo those processes, as
needed. In short, the EDRs/ESPRs provide a planning context which complements the individual project-
specific filings.

54 Certificate of the Secretary of the Executive Office of Environmental Affairs on the Logan Airport 1997 Annual Update, issued on
October 16, 1998.

Boston-Logan International Airport 2016 EDR 
Introduction/Executive Summary 1-46 
In the last several years, aircraft operations and passenger activity levels and associated environmental
effects have remained well below levels previously analyzed for Logan Airport. Thus, the forecasted
aviation growth presented in the 2004 ESPR , the predicate upon which the ESPR schedule was initially
established, has not occurred. Accordingly, with the approval of the Secretary, Massport prepared 
2009 and 2010 EDRs in lieu of the ESPR originally planned for 2009. The 2011 ESPR , filed in early 2013,
reported on calendar year 2011 and updated passenger activity level and aircraft operations forecasts. The 
2012/2013 EDR presented conditions for both calendar years 2012 and 2013. The 2014 EDR and 2015 EDR 
presented conditions for calendar years 2014 and 2015. 
This 2016 EDR provides a comprehensive, cumulative analysis of the effects of all Logan Airport activities
based on actual passenger activity and aircraft operation levels in 2016, and presents environmental
management plans for addressing areas of environmental concern. Massport proposes to prepare a 
2017 ESPR to report on activity levels and environmental conditions for that year and projections through
2035, and anticipates publishing this report by early 2019. Where appropriate, Massport will continue to
identify and address any longer-term aviation and environmental trends in both EDRs and ESPRs. As
directed in the Secretary’s Certificate on the Terminal E Modernization Project ENF, the EDR/ESPR will
continue to be the forum to address cumulative, Airport-wide impacts. 
Project-Specific Review 
While this Airport-wide review provides the broad planning context for proposed projects and future
planning concepts, certain Airport projects are also subject to a project-specific, public environmental
review process when they meet state environmental review thresholds. When required, Massport and
Airport tenants submit ENFs and EIRs pursuant to MEPA. Similarly, where NEPA 55 environmental review is
triggered, projects are reviewed under the NEPA environmental review process.

Activity Levels 
Introduction 
Boston-Logan International Airport (Logan Airport or Airport) plays a number of roles in the local, New England,
and national air transportation systems. It is the primary airport serving the Boston metropolitan area, the
principal New England airport for long-haul services, and a major U.S. international gateway airport for
transatlantic services. 
This chapter reports on annual air traffic activity at
Logan Airport in 2016, including air passengers,
aircraft operations, aircraft fleet mix, and cargo
volumes. Air traffic and passenger activity levels at
Logan Airport are the basis for the evaluation of
noise, air quality effects, and ground access
conditions associated with the Airport. In this
chapter, current activity levels at the Airport are
compared to prior-year levels, and historical
passenger and operations trends at Logan Airport
dating back to 2000 are reviewed. 1 
Logan Airport is an important origin and destination (O&D) 2 airport both nationally and internationally, and is
one of the fastest growing major U.S. airports, in terms of number of passengers, over the past five years. 3 In
2016, U.S. passenger traffic grew by 3.8 percent, whereas Logan Airport experienced a passenger growth of
8.5 percent, more than double during the same period. 4 In 2016, passenger activity levels reached an all-time
high of 36.3 million passengers and aircraft operations totaled 391,222. From 2000 to 2016, the annual number
of passengers at Logan Airport increased by 30.9 percent, while the annual number of aircraft operations 5 
decreased by 19.8 percent. Despite the increase in passengers, aircraft operations at Logan Airport remained well
below the 487,996 operations in 2000 and the historical peak of 507,449 operations reached in 1998.
Logan Airport’s market demand and passenger levels are a result of the Boston metropolitan area’s status as an 
1 Refer to Appendix E, Activity Levels for available information dating back to 1980. 
2 “Origin and destination” traffic refers to the passenger traffic that either originates or ends at a particular airport or market. A strong
O&D market like Boston generates significant local passenger demand, with many passengers starting their journey and ending their
journey in that market. O&D traffic is distinct from connecting traffic, which refers to the passenger traffic that does not originate or end
at the airport but merely connects through the airport en route to another destination. 
3 Between 2011 and 2016, Logan Airport was the 8 th fastest growing airport in the U.S. in terms of domestic O&D traffic (U.S. DOT O&D Survey).

Air Passenger Levels in 2016 
The following section provides an overview of air passenger levels in 2016 for Logan Airport. 
Logan Airport Passengers 
Logan Airport is the principal airport for the greater Boston metropolitan area, and the international and
long-haul gateway for much of New England. Logan Airport was ranked the 17 th busiest airport in the U.S. in
terms of passengers in 2016. 6 Logan Airport served 36.3 million passengers in 2016, an increase of 8.5 percent
over 2015. This represented a historic high for Logan Airport, exceeding the previous record of 33.4 million in
2015. Logan Airport is one of the fastest growing airports in the U.S., with passenger growth continuing to
outpace overall U.S. passenger growth. Factors that contributed to the strong passenger growth at Logan Airport
in 2016 included: 
 Continued economic growth and an increase in air travel demand across the nation, especially in
Massachusetts and the Boston metropolitan area; 
 JetBlue Airways’ continued growth at Logan Airport in response to passenger demand; and 
 Increasing international passenger demand accommodated with new international services at
Logan Airport. 
International passenger traffic at Logan Airport, in particular, has exhibited strong growth over the past several
years. After three periods of decline and gradual recovery in 2001, 2006, and 2008, Logan Airport’s international
traffic finally surpassed 2000 levels for the first time in 2013. In 2016, international passengers made up
approximately 18 percent of total Airport passengers, an increase of 19 percent over 2015 and 32 percent over
2014 levels. Since 2010, the international passenger segment has averaged a 10.2 percent annual growth. This
growth has been driven by strong market demand, resulting in the growth of JetBlue Airways and Delta Air Lines’
international service at Logan Airport, as well as a rapid increase in foreign carrier services in recent years. Boston
is currently the 11 th largest U.S. gateway for international air travel, and the largest U.S. gateway airport that is
not a connecting U.S. airline hub. 7 The O&D strength of the Boston market makes Logan Airport an attractive
gateway for international airlines. Additional trends in new aircraft technology allowing for smaller and more
fuel-efficient aircraft on international routes are also expected to continue to benefit mid-size O&D markets like
Boston. 
Logan Airport is a primary economic engine for the New England region, the state, and the Boston metropolitan
area. It supports nearly 132,000 direct and indirect jobs, 8 while generating approximately $13.3 billion per year in
total economic activity. International passengers contribute a substantially higher share to the local and regional
economy than domestic passengers do. Approximately 1.6 million overseas visitors visited the Boston area in

2015, 9 spending more than $1 billion; 10 this visitor level represented a 14 percent increase from 2014 and is
widely attributed to the increased international service at Logan Airport, particularly non-stop flights to China
and Hong Kong. 11 However, in 2016, the number of international overseas visitors to Boston declined by
5 percent to 1.5 million. 12 New international service in the last five years alone has contributed more than
$1.3 billion per year to the local economy and $49 million in new incremental tax revenue through income and
sales. 13 
As shown in Table 2-1 , domestic air passengers represent Logan Airport’s largest market segment, accounting
for 81.5 percent of total passengers in 2016. The domestic passenger market increased by 6.4 percent in 2016.
Growth in JetBlue Airways’, Southwest Airlines’, and Spirit Airlines’ domestic networks from Logan Airport were
the main contributors to growth in domestic passengers. JetBlue Airways carried 8.9 million domestic passengers
at Logan Airport in 2016, compared to 8.1 million in 2015. Southwest Airlines carried 3.0 million domestic
passengers in 2016, up 16.6 percent from 2.6 million passengers in 2015. Spirit Airlines carried 1.0 million
domestic passengers in 2016, up 53.4 percent from 0.6 million passengers in 2015. 14 
Figure 2-2 shows the total annual passengers for the five major airlines at Logan Airport and highlights the rapid
growth of JetBlue Airways at Logan Airport since 2004. The figure also shows a sixth airline, US Airways, which
merged with American Airlines in 2013. Overall, the substantial low-cost carrier growth at the Airport over the
past decade – particularly the entry of JetBlue Airways in 2004 and its subsequent decision to expand and make
Logan Airport one of its focus cities – has exceeded recent consolidation and contraction among other carriers
serving Logan Airport. 15 Domestic passenger activity levels have recovered from the economic downturn in
2008/2009, when the total number of domestic air passengers fell to 21.8 million. In 2016, domestic passenger
activity levels reached a new peak of 29.6 million.

airline mergers. The decreases in RJ operations also reflect the retirement of smaller, less fuel-efficient RJs with 30
to 50 seats. 
The change in mix of passenger aircraft operations since 2000 is shown in Figure 2-7 . RJs accounted for
10 percent of total passenger operations in 2016, compared to 31 percent at the peak level in 2005. Similarly,
non-jets have declined from 34 percent in 2000 to 13 percent in 2016. 
Figure 2-7 Passenger Aircraft Operations at Logan Airport by Aircraft Type, 2000-2016 
Passengers per Aircraft and Load Factors 
The average number of passengers per aircraft operation increased in 2016, continuing the long-term trend. An
increase in the average number of passengers per aircraft operation indicates an increase in the average aircraft
seating capacity and/or an increase in the percentage of aircraft seats occupied by passengers (i.e., load factor 19 ).
Load factors at Logan Airport have matched or exceeded the national average each year since 2012. Changes in
the number of passengers per operation and load factors at Logan Airport are shown in Figure 2-8 . In 2016,
Logan Airport operations accommodated an average of 92.8 passengers per flight compared to 89.7 in 2015
( Table 2-3 ). The average number of passengers per flight has risen by 19.3 percent since 2010 when the average
number of passengers per flight was 77.8. The trend of more passengers on fewer flights is more efficient,
reflecting a shift away from smaller, less fuel-efficient aircraft and rising load factors as airlines carefully
monitored and restricted capacity growth. In 2016, Logan Airport’s average domestic load factor was
82.8 percent, unchanged from 2015. The national average domestic load factor decreased during the same
period, falling from 82.6 percent in 2015 to 81.7 percent in 2016. 20

General Aviation Operations 
GA is defined as all aviation activity other than commercial airline and military operations. It encompasses a
variety of aviation activities at Logan Airport, including: corporate/business aviation, private business jet charters,
law-enforcement, and emergency medical/air ambulance services. GA operations are conducted by a diverse
group of private and business aviation aircraft ranging from single-engine piston driven aircraft to
high-performance, long-range jets. GA activity at Logan Airport declined following the 2008/2009 economic
recession, but recovered in 2011. Lower oil prices and decreased fuel expenses over the past two years have
contributed to an increase in GA activity at Logan Airport. GA operation levels in 2016 remain well below the
35,233 GA operations that Logan Airport handled in 2000. In 2016, GA operations at Logan Airport totaled
30,780 operations which increased 9.3 percent from the 28,166 operations in 2015. 
In 2016, GA operations accounted for 7.9 percent (30,780 operations) of aircraft activity at Logan Airport
( Figure 2-4 ). Hanscom Field remains the primary GA airport for the Greater Boston region, accommodating four
times the number of GA operations than at Logan Airport. Hanscom Field accommodated 120,891 GA operations
in 2016, representing 99.3 percent of Hanscom Field’s aircraft activity. Figure 2-9 depicts changes in number of
Logan Airport aircraft operations by category since 2000.

Notes: Jet, regional jet, and non-jet operations are associated with commercial passenger and all-cargo airlines.
GA operations also include jet and non-jet aircraft, but are associated with private charter and corporate use. 
All-Cargo Operations 
Operations by cargo-dedicated aircraft represent less than 2 percent of aircraft activity at Logan Airport.
All-cargo carriers at Logan Airport include FedEx, UPS, DHL, and a few other smaller carriers. In 2016, all-cargo
operations at Logan Airport totaled 6,680 operations, an increase of 10.2 percent compared to 2015.

Airline Passenger Service in 2016 
Airlines can adjust service at an airport or on a specific route in two ways: changing the number of flights
operated or changing the size of the aircraft. Changes in flight frequency and changes in aircraft size both affect
the number of seats available to passengers (seat capacity). Airline services are therefore typically discussed in
terms of seat capacity as well as the number of flight departures. 21 This section examines changes in airline
departures and seat capacity at Logan Airport in 2016 and provides an overview of new and discontinued routes. 
Service Developments at Logan Airport 
In 2016, 41 airlines provided scheduled passenger service from Logan Airport to 129 non-stop destinations. 22 The
average non-stop stage length (the average length of non-stop flights) of scheduled domestic flights from
Logan Airport increased from 811 miles in 2015 to 837 miles in 2016. The average non-stop stage length of
scheduled international flights increased from 2,109 miles in 2015 to 2,249 miles in 2016. The major changes in
Logan Airport’s scheduled passenger services in 2016 are described below. 
Changes in Domestic Passenger Service 
As shown in Table 2-4 , the total number of scheduled domestic flights at Logan Airport in 2016 increased by
2.6 percent compared to 2015. Overall, scheduled jet operations by legacy carriers and low-cost carriers
increased by 4.3 percent in 2016, while regional/commuter flights decreased by 3 percent. 
Legacy carrier jet operations decreased slightly from 114,987 operations in 2015 to 114,012 operations in 2016.
This slight decrease is due to American Airlines’ schedule adjustments following its recent merger with US
Airways. In 2016, American Airlines reduced jet operations by 2.4 percent from the combined 56,222 operations
performed by American Airlines and US Airways in 2015. Legacy carrier RJ operations declined more significantly,
by 37.9 percent to 6,418 operations in 2016. 
Total domestic low-cost carrier operations grew by 9.7 percent in 2016, increasing from 110,642 operations in 2015 to
121,369 operations in 2016. Low-cost carriers accounted for 40 percent of Logan Airport’s total scheduled domestic
operations in 2016. JetBlue Airways, the dominant low-cost carrier at Logan Airport, continued to expand, increasing
its domestic operations by 6.6 percent from 79,364 operations in 2015 to 84,590 operations in 2016. Southwest
Airlines increased domestic operations by 13.4 percent from 21,542 operations in 2015 to 24,436 operations in 2016.
In 2016, ultra-low-cost carrier Spirit Airlines expanded operations at Logan Airport, increasing domestic operations by
48 percent from 4,896 operations in 2015 to 7,245 operations in 2016. Since 2014, Spirit Airlines has increased
domestic jet operations by 146 percent. 
Regional commuter flights were down by 2.9 percent in 2016 due to reductions by American Airlines and United
Airlines regional affiliates. Delta Air Lines increased regional operations by 20.2 percent in 2016 after significantly
decreasing regional operations in 2015. 
21 A departure is an aircraft take-off at an airport. While aircraft operations include both departures and arrivals, airline services are
typically described in terms of departures, as the number of scheduled departures generally equals the number of scheduled arrivals.
Changes in departures translate to changes in overall operations.

2 Low-cost carriers that provided domestic service at Logan Airport in 2016 included JetBlue Airways, Southwest Airlines, Spirit
Airlines, Virgin America, and Sun Country Airlines. 
Highlights of key domestic airline service changes at Logan Airport in 2016 include: 
 JetBlue Airways continued to grow operations from Logan Airport. In 2016, the airline averaged over 120
daily departures from Logan Airport. New domestic destinations introduced in 2016 included Nashville,
New York LaGuardia (LGA), and Salt Lake City. JetBlue Airways also added frequencies in markets
including Fort Lauderdale, Fort Myers, and Tampa. As Logan Airport’s largest carrier, JetBlue Airways
accounted for 27.8 percent of total domestic passenger aircraft operations and 26.8 percent of total
passengers in 2016. 
 Delta Air Lines continued to add airline departures and seat capacity at Logan Airport in 2016, adding
frequencies and capacity to several traditionally strong markets and increasing service on newly
competitive routes. After significantly increasing capacity on the Boston-New York LGA Delta Shuttle
route in 2015, Delta shifted some of the frequencies to regional partners in 2016, reducing total capacity
on the Boston-New York LGA Delta Shuttle route by 8 percent from 2015. However, Delta Air Lines
added frequencies in the New York (JFK), Los Angeles, and Salt Lake City markets. Delta Air Lines also
introduced new non-stop service from Logan Airport to Seattle and Nashville in 2016. 
 American Airlines reduced domestic operations and capacity at Logan Airport in 2016, as part of the
integration process with US Airways following the American Airlines/US Airways merger in
December 2013. The carrier did not discontinue any existing routes or add any new routes in 2016, but it
did make several capacity adjustments at Logan Airport. Overall, American Airlines reduced domestic
seat capacity at Logan Airport by 3.7 percent in 2016. Frequencies were reduced in markets including
Buffalo, New York JFK, New York LGA, Philadelphia, Pittsburgh, and Syracuse. Minor capacity reductions
were made in several other key markets such as Dallas/Fort Worth, Miami, Chicago Midway, and Phoenix.
American Airlines increased capacity to Washington DCA, Los Angeles, and Harrisburg.

 Spirit Airlines significantly expanded its network at Logan Airport in 2016 building on its strong growth in
2015. Spirit Airlines increased total seat capacity by approximately 53 percent in 2016. The airline
launched new service to Baltimore, Orlando, and Minneapolis in 2016. Spirit Airlines also increased
operations frequency to Fort Lauderdale. 
 Southwest Airlines increased seat and operations capacity from Logan Airport in 2016 despite
introducing no new routes. All new services launched in 2015 were continued in 2016 including services
to Columbus, Indianapolis, Dallas Love Field, and Austin. Additional capacity was also added to markets
such as Nashville, Baltimore, Denver, Houston Hobby, and Chicago Midway.
