Re: Boston Logan International Airport 2020/2021 Environmental Data Report - EEA #3247 
Dear Secretary Card and Director Kim: 
On behalf of the Massachusetts Port Authority (Massport), we are pleased to submit this 2020/2021 
Environmental Data Report (EDR) for Boston Logan International Airport (Logan Airport or the
Airport). This filing continues Massport’s over four-decade practice of providing an extensive record
of Logan Airport environmental trends, facility planning, operations and passenger data, and
Massport’s mitigation commitments. At the Secretary’s direction, this combined 2020/2021 EDR 
provides an overview of an extraordinary period in the history of Logan Airport resulting from the
ongoing COVID-19 pandemic. 
The dramatic nature of the COVID-19 pandemic, and its global impacts, the US and local economies,
and to the aviation industry in particular, were more intensely experienced at Logan Airport than
many other US airports. Beginning in March 2020, flights in and out of Logan Airport were reduced
and passenger levels dropped by over 90 percent at the peak of the pandemic in the spring and
summer of 2020. 2020 annual passengers dropped to levels of activity not seen since the mid-1970s.
There were far fewer aircraft operations, passengers, and ground traffic, and a similar drop in overall
Logan Airport activity. Activity levels began a slow recovery in mid-summer 2020 and continued
through 2021. For the first 8 months of 2022 (January to August), operations were down 13 percent
and passengers were down 18 percent compared to the first 8 months of 2019. 
As a result of this significant reduction in Airport activity and revenues, Massport, our airlines, and
other tenants adjusted their capital and operations plans. Concurrently, the schedule for a number of
Airport projects and programs have been adjusted. Chapter 3, Airport Planning , includes the most
current project updates through the end of September 2022. 
Logan Airport passenger and operational levels are generally tied closely to the strong local, regional,
national, and international economies and its role as the major airport to a region that is the home to
world-class educational and medical institutions, cutting-edge technology companies, rich historical
resources, and extensive tourism. Logan Airport’s recovery and the timeframe will similarly be driven
by the national and regional economic recovery. 
As the economic recovery advances, Massport continues to evaluate and carefully plan for the
recovery of aircraft operations and air passenger activity, and remains committed to implementing
the broad range of environmental and operating strategies designed to reduce the impacts

Secretary Bethany A. Card Page 2 November 15, 2022 
associated with Airport operations. Most notable is the early 2022 announcement of Massport’s
“ Roadmap to Net Zero ”. This bold, Authority-wide environmental initiative aims to reduce
Massport-controlled emissions to net zero by 2031, the 75 th anniversary of the Massachusetts Port
Authority. As one of New England’s largest transportation hubs, emission reduction at Logan Airport
is a centerpiece of this program. By addressing building efficiency, transitioning to clean energy,
updating our vehicle fleets to electric vehicles, and collaborating with our tenants, airlines, and other
business partners, we have the opportunity to dramatically reduce emissions in a way that will
improve air quality while still serving as a regional economic engine. 
Massport will continue to seek opportunities to implement measures designed to reduce Logan
Airport’s operating and environmental impacts. Such measures are tied to High Occupancy Vehicle
(HOV) strategies, noise abatement procedures, emission reduction and energy efficiency measures,
as well as continued information sharing with interested stakeholders and our neighbors. 
Additionally, this EDR, in response to community input, includes discussion on the evolving science
and studies of aircraft noise and emissions and associated public health investigations. Through both
this EDR and future EDRs/ESPRs, we hope both to share the most recent, available information and,
where possible, support those studies that will ultimately guide evolving regulations and mitigation
strategies. 
EDR Content and Structure 
The 2020/2021 EDR responds to the Secretary’s Certificate on the Boston Logan International Airport
2018/2019 EDR dated March 2021. The EDR also updates conditions for the following categories: 
• 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 Environmental Compliance and Management/Water Quality); 
• Status of Logan Airport project mitigation; and 
• Sustainability initiatives. 
The 2020/2021 EDR includes the Secretary’s Certificate on the Boston Logan International Airport
2018/2019 EDR and associated comment letters. Certificates received on the Logan Airport Parking
Project (EEA# 15665) and Terminal E Modernization Project (EEA# 15434), which included items to be
addressed in future EDRs and ESPRs are also included. Appendix D, Distribution presents the EDR
distribution list and supporting technical appendices are available electronically. 
Review Period, Distribution, and Consultation 
As we have done in the past for multi-year documents, Massport has requested EEA’s consideration of
an extended public comment period for this EDR. Based on this request, the public comment period
will begin on November 23, 2022, the publication date of the next MEPA Environmental Monitor , and
will end on January 6, 2023. The distribution list included as Appendix D indicates which listed parties
will receive a digital and/or printed copy of this EDR or notice of availability. As with the recent EDRs

Introduction/Executive Summary 
Introduction 
The Massachusetts Port Authority (Massport) is continuing its over four-decade practice of providing an
extensive record of Boston Logan International Airport (Logan Airport or Airport) environmental trends, facility
planning, operations and passenger levels, and Massport’s mitigation commitments in this Boston Logan
International Airport 2020/2021 Environmental Data Report (EDR) . Per the request of the Secretary of the
Massachusetts Executive Office of Energy and Environmental Affairs (EEA), this 2020/2021 EDR combines data
and analysis for calendar years 2020 and 2021. 
This EDR reports on 2020 and 2021, reflecting the significant changes at Logan Airport and throughout the
aviation industry occurring as a result of the ongoing COVID-19 pandemic. Where available, Massport has
included relevant updates through fall 2022 where the current conditions have resulted in changes in projects or
programs that were in place in 2019 and prior. By year-end 2020, total flight operations were down
approximately 50 percent and passenger levels were down by about 70 percent compared to year-end 2019,
dropping to levels of activity not seen since the 1970s. However, aircraft operations increased in 2021, with total
flight operations and passenger levels recovering to approximately 62 percent and 53 percent, respectively, of
2019 levels, showing a gradual return towards 2019 levels. 
Air traffic declines caused by economic recessions and other “shocks” such as the events of September 11, 2001
and the Great Recession (Global Financial Crisis [GFC]) in 2008/2009 have been followed by gradual recovery
cycles, as depicted in Figure 1-1 , evidenced by a five year recovery after the events of September 11, 2001 and a
three year recovery after the GFC. Nationally, as shown in Figure 1-2 , 80 percent recovery to 2019 demand levels
occurred in July 2021 as travel restrictions loosened and vaccines were made widely available. In December 2021,
passenger demand at U.S. airports recovered to approximately 83 percent of 2019 levels. Much of the remaining
recovery will be dependent on the return of both business travel and international travel, since domestic capacity
across the U.S. has almost fully returned to 2019 levels. Full recovery will also be influenced by airline staffing. 
As shown in Figure 1-3 , demand in Boston, while nearing a 70 percent return to 2019 levels in late 2021, has
lagged behind national demand by between 10 and 15 percent. This aligns with recovery patterns in other
coastal urban markets where business travel and international travel have been slower to return to pre-pandemic
levels. International passenger activity levels at Logan Airport are expected to return in 2022 and beyond. 
COVID-19 is having an unprecedented impact on not just the aviation industry but the global economy. While
the immediate and most pressing concern is human cost, COVID-19 has created profound implications for nearly
all businesses and industries. The impact on aviation has been particularly severe. The situation is changing on a
daily basis and there remains considerable uncertainty as to the near- and long-term impacts of the pandemic.

Introduction/Executive Summary 1-2 
Source: Massport. 
Notes: Logan Airport terminal (left) and baggage claim area (right) during the COVID-19 pandemic. 
As a result of this significant reduction in Airport activity and dramatic reduction in revenues, both Massport, the
airlines, and other tenants necessarily adjusted and scaled back their operations in 2020 and 2021. In response, a
number of Airport projects and programs have been revised and pushed back. To be as transparent as possible,
Chapter 3, Airport Planning includes the most current project updates through September 2022. Forthcoming
EDRs and Environmental Status and Planning Reports (ESPRs) will continue to provide updates, as available.
Overall, Massport continues to evaluate and plan for the recovery of aircraft operations and air passenger activity
and remains committed to implementing the broad range of environmental and operating strategies designed to
reduce the impacts associated with Airport operations.

Boston Logan International Airport 2020/2021 EDR 
Introduction/Executive Summary 1-4 
Logan Airport, owned and operated by Massport, plays a key role in the metropolitan Boston and New England
passenger and freight 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. The Airport boundary encompasses about 2,400 acres in East Boston and Winthrop,
including about 700 acres in Boston Harbor. Logan Airport’s airfield comprises six runways, about 15 miles of
taxiway, and about 240 acres of concrete and asphalt apron. Logan Airport has four interconnected passenger
terminals (Terminals A, B, C, and E), each with its own ticketing, baggage claim, and ground transportation
facilities. The Airport is less than a three-mile drive from downtown Boston and is accessible by public transit
lines, several direct bus lines, and a well-connected roadway system. Massport provides Logan Express bus
service to and from Logan Airport for air passengers and employees from a series of park-and-ride lots. 
This 2020/2021 EDR is one in a series of annual environmental review documents submitted to the Secretary of
EEA, in accordance with the Massachusetts Environmental Policy Act (MEPA). 1 Since 1979, Massport has
submitted these documents 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 assessment on airport
activities was prepared, and Massport continues to be a leader in environmental reporting. 
Approximately every five years, Massport prepares an ESPR, which provides a historical and prospective view of
Logan Airport. EDRs, prepared annually in the intervals between ESPRs, provide a historical review of
environmental conditions for the reporting year compared to the previous year. This 2020/2021 EDR follows the 
2018/2019 EDR which reported on 2018 and 2019 conditions. The last ESPR used 2017 as its base year. While
Massport and the entire aviation industry continue to adjust to the evolving operating conditions, we continue to
evaluate the pandemic’s current and future impacts. Where possible, this EDR includes relevant information and
updates. However, more detailed projections and analyses will be addressed in the forthcoming 2022 ESPR . 
At the request of the Secretary following her review of the 2018/2019 EDR , Massport was directed to prepare this
combined 2020/2021 EDR and its scope was established by the Secretary‘s Certificate on the 2018/2019 EDR 
dated March 19, 2021, which is included in Appendix A, MEPA Certificates and Responses to Comments . This EDR
fulfills all requirements laid out in the Secretary’s Certificate on the 2018/2019 EDR , includes responses to
comments on the Secretary’s Certificate, and updates and compares the data presented in the 2018/2019 EDR 
for the following subjects:

Logan Airport Environmental Review Process 
This 2020/2021 EDR is Massport’s next filing in its unique, but well-established, formal state-level environmental
review process that assesses Logan Airport’s cumulative environmental impacts. The documents provide a
current and historical 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 Process 
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 2 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 
2 Certificate of the Secretary of the Executive Office of Environmental Affairs on the Logan Airport 1997 Annual Update, issued on
October 16, 1998.

Introduction/Executive Summary 1-6 
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 National Environmental Policy Act
(NEPA) review thresholds must undergo those processes, as needed. In short, the EDRs/ESPRs provide a
cumulative planning context which complements the individual project-specific filings. 
In 2018 and 2019, while passenger levels experienced significant growth, reaching new peaks, aircraft operations
and associated environmental effects 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 combined 2012/2013 EDR 
presented conditions for both calendar years 2012 and 2013. The 2014 EDR , 2015 EDR , and 2016 EDR presented
conditions for calendar years 2014, 2015, and 2016, respectively. Similarly, with strong passenger growth and
evolving ground access trends with the emerging RideApp industry (formerly referred to as transportation
network companies [TNCs]), EEA allowed Massport to defer the 2016 ESPR . 
The 2017 ESPR provided a comprehensive, cumulative analysis of activity levels and environmental conditions for
2017 and a Future Planning Horizon. In the ESPR, Massport proposed preparation of a combined 2018/2019 EDR 
to report the effects of all Logan Airport activities based on actual passenger activity and aircraft operations in
2018 and 2019. As noted above, due to the COVID-19 pandemic, the Secretary required Massport file a
combined 2020/2021 EDR to begin to evaluate post-pandemic growth trends. 
While this report is largely focused on 2020 and 2021, Massport has noted preliminary recovery highlights that
will be further evaluated in the 2022 ESPR. Where appropriate, Massport will continue to identify and address any
longer-term aviation and environmental trends in both EDRs and ESPRs. 
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
Environmental Notification Forms (ENFs) and Environmental Impact Reports (EIRs) pursuant to MEPA. Similarly,
where NEPA 3 environmental review is triggered, projects are reviewed under the NEPA environmental review
process. 
Massport understands that MEPA amended its regulations under 301 CMR 11.00 as of December 24, 2021.
Additionally, MEPA released the MEPA Interim Protocol on Climate Change Adaptation and Resiliency, effective for 
3 42 USC Section 4321 et seq. The Federal Aviation Administration (FAA) implements NEPA through FAA Order 1050.1F, Environmental
Impacts: Policies and Procedures, Federal Aviation Administration, United States Department of Transportation, Effective Date: July 16,
2015.

all new filings as of October 1, 2021, and the MEPA Public Involvement Protocol for Environmental Justice
Populations and MEPA Interim Protocol for Analysis of Project Impacts on Environmental Justice Populations, 
effective for all new filings as of January 1, 2022. All projects at Logan Airport that are filed with MEPA will
comply with these amended regulations and protocols. Future EDRs and ESPRs will document mitigation
commitments from its projects that support these updates in Chapter 9 , Environmentally Beneficial Measures and
Project Mitigation Tracking . 
Current and potential future projects anticipated to undergo MEPA and/or NEPA review are discussed in
Chapter 3, Airport Planning . 
2020/2021 EDR Outreach 
Although EDRs and ESPRs are not projects subject to the MEPA Public Involvement Protocol for Environmental
Justice Populations, Massport recognizes the importance of a robust outreach approach to ensure the public is
aware of these reports and has an opportunity to review and comment. The distribution list for EDR and ESPR
filings is routinely updated to include numerous organizations, residents, and agencies that have expressed
interest in these reports. Additionally, this Executive Summary has and will continue to be translated in Spanish. 
However, in light of the MEPA Public Involvement Protocol for Environmental Justice Populations , Massport has
embarked on an expanded outreach process for this 2020/2021 EDR , and intends to continue further developing
its outreach approach for future filings. 
The following measures have been implemented for this filing: 
 Post a social media announcement notifying the public of
upcoming filing. 
 Circulate the 2020/2021 EDR electronically to the Environmental
Justice (EJ) Reference List provided by MEPA for Massport’s
recent Runway 9-27 Runway Safety Area Improvement Project.

Additionally, Massport recognizes the importance of ongoing engagement with the community and
organizations. The following highlights a couple of these engagement efforts: 
 Massport renewed an agreement to provide funding to the East Boston Neighborhood Health Center to
help expand the efforts of their Asthma and Chronic Obstructive Pulmonary Disease (COPD) Prevention
and Treatment Program in East Boston and Winthrop that provides services including screenings for
children, distribution of asthma kits, and home visits, among others. 
 Massport supports, where possible, the Massport Community Advisory Committee (CAC). The Massport
CAC is a state-legislated body that works with Massport on a range of Authority-wide topics, including
environmental issues. Further information about the Massport CAC can be found at 
https://massportcac.org/ . 
Logan Airport Planning Context 
Logan Airport plays a key role in the metropolitan Boston and New England passenger and freight transportation
networks. The Airport is one of the most land-constrained airports in the nation and is surrounded on three sides
by Boston Harbor (see Figures 1-4 and 1-5 ). 
Passenger and Aircraft Activity Growth at Logan Airport 
Consistent with the rest of the U.S. airport industry, Logan Airport experienced steep declines in airline activity
and passenger volumes over the past two years. Different states and regions within the U.S. have differed in their
response to COVID-19 restrictions which in turn reflected the willingness of consumers to resume travel to and
from particular markets. The net result is that air travel recovery at Logan Airport continues to be a work in
progress. Although 2020 passengers dropped to levels of activity not seen since the 1970s, in 2021 the Airport
showed a gradual return towards 2019 levels ( Figure 1-6 ). 2022 has shown further recovery, but not to
pre-pandemic levels. 
Starting in March 2020, Logan Airport experienced dramatic reductions in passenger levels and flights, associated
with the COVID-19 pandemic. Passenger activity levels totaled approximately 12.6 million in 2020, a decrease of
70.3 percent compared to 2019 levels. The total number of aircraft operations at Logan Airport declined by 51.6
percent, from 427,176 operations in 2019 (which was a historic peak since 2001) to 206,702 operations in 2020. 
In 2021, the Airport continued its recovery path, and added 10.0 million passengers, ending the year with about
22.7 million, recovering to approximately 53.3 percent of 2019 passenger levels. 2021 operations increased to
266,034 operations, representing a recovery of 62.3 percent of 2019 levels.

Figure 1-6 Logan Airport Annual Passenger Levels and Aircraft Operations (1990–2021) 
Logan Airport Activity Levels are Closely Tied to the Regional and
National Economy 
Activity levels at Logan Airport are largely driven by the local, regional, and national economies. As can be
seen by looking at long-term trends, it is clear that when the economy is strong, Logan Airport grows.
Similarly, the most significant declines in passenger levels and aircraft operation track closely with
significant national and international disruptions. Examples of the most significant declines include the
Professional Air Traffic Controllers Organization (PATCO) strike in 1981, September 11, 2001, the Great
Recession in 2008/2009, and now the COVID-19 pandemic. 
When there has been significant growth, as was observed through 2018 and 2019, Massport has
implemented strategies to address that growth in a manner that allows Logan Airport to evolve in a
sustainable and environmentally responsible way. 
Logan Airport is the largest airport in the six-state New England region, which has a population of
approximately 15.1 million residents in 2021. The Airport is located in Massachusetts, which is home to
approximately 7.0 million residents, or nearly 46.6 percent of New England’s population as of 2021. Logan
Airport serves 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.

Introduction/Executive Summary 1-12 
Prior to COVID-19, the Boston metropolitan area had consistently maintained a lower unemployment rate
compared to the Commonwealth and the nation. In 2019, the Boston metropolitan statistical area had an
unemployment rate of 2.8 percent, which was lower than both the rate in the Commonwealth (3.1
percent) and the country (3.7 percent). Even during the 2008/2009 economic downturn, Boston and the
Commonwealth experienced unemployment rates below the national average. 4 Massachusetts recorded a
recent historical high unemployment rate of 16.7 percent in April 2020, which was greater than the
national unemployment rate of 14.4 percent the same month. 5 After reaching record-high unemployment
rates at the height of the pandemic in 2020, the Commonwealth’s unemployment rate continued to fall
steadily in the remaining months of 2020 and through 2021, falling to 4.1 percent in December 2021. The
Airport not only serves a growing population, but a high earning one as well. Per capita income in 2020
was estimated at $85,724 (current U.S. dollars) in the Airport’s primary service area, 11.3 percent higher
than the Commonwealth and 44.9 percent higher than the national average. 6 
Logan Airport is a key transportation and economic resource in the New England region, the state, and
the Boston metropolitan area, which is home to a broad range of industries and with a relatively wealthier
population when compared to the U.S. average. The industries accounting for the largest share of
employees include healthcare and social assistance; 7 educational services; and professional, scientific, and
technology services (which include Boston’s growing biotech industry). 8 In 2019, Boston/Cambridge, the
nation’s largest biopharma cluster, committed to advancing digital health through creation of a digital
health record database where the industry is expected to grow to generate more than $350 billion in
annual value by 2025. 9 Even during the height of the global pandemic that caused an economic downturn
in other business sectors, the Commonwealth’s biopharma industry continued to thrive, adding about
85,000 jobs and raising over $5.8 billion in venture capital. 
In addition to supporting the growth and economic success of the state, Logan Airport and the airport
industry have always been important elements in the state and regional economies. The Massachusetts
Statewide Airport Economic Impact Study Update, completed by the Massachusetts Department of
Transportation (MassDOT) in 2014 and most recently updated in 2019, 10 estimates that Massport airports
– inclusive of Logan Airport, Worcester Regional Airport, and Hanscom Field – contribute approximately
$23.1 billion in output to the Massachusetts economy annually; of this output, 71 percent is due to Logan
Airport alone. 11 Total output includes on-Airport businesses, construction, visitor, and multiplier effects

Notes: “Massachusetts Totals” refers to the total economic output of all Massachusetts airports. 
Logan Airport is considered an origin and destination (O&D) 14 airport both nationally and internationally,
meaning that approximately 90 percent of Logan Airport passengers’ trips either start or end at Logan
Airport. Hub airports, such as Atlanta or Chicago, serve many more passengers annually but, compared to
O&D airports like Logan Airport, a higher percentage of passenger traffic at hub airports passes through
to connecting flights. Logan Airport is considered a domestic and international O&D airport, meaning that
less than 10 percent of air passengers are connecting through Logan Airport. 
12 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.

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.

Boston Logan International Airport 2020/2021 EDR 
Introduction/Executive Summary 1-14 
Forecast Status 
The 2017 ESPR presented an updated forecast for Logan Airport aircraft operations and passenger activity.
That forecast focused on a Future Planning Horizon including a projected 50 million annual air passengers
and 486,000 annual aircraft operations. Massport’s ESPR forecast was consistent with the Federal Aviation
Administration’s (FAA’s) Terminal Area Forecast at that time. However, the COVID-19 pandemic has
dramatically reduced air passenger traffic in 2020 and 2021, with a return to 2019 levels not expected in
the near term. 
Due to the strong economy in the months prior to the start of the COVID-19 pandemic, passenger activity
levels and aircraft operations at Logan Airport increased rapidly. That growth was largely driven by the
positive economic conditions in the Boston region, low unemployment, a strong, diverse economic base,
and continued investment in commercial and residential real estate, particularly in life sciences, finance,
healthcare, and higher education. As with other airports across the U.S., this growth trend was upended in
March 2020 at the start of the pandemic. 
Accordingly, the 2017 ESPR projections will need to be updated as the longer-term impacts of the
COVID-19 pandemic are better understood. The methodology for the upcoming 2022 ESPR forecasts will
be prepared using standard industry forecasting techniques, which include analyzing: 
 Historical patterns of airport traffic and airfares; 
 Historical socioeconomic and demographic data; 
 Airline strategies and industry trends; and 
 Forecasted socioeconomic and demographic data. 
This methodology is similar to that used by the FAA to develop the Terminal Area Forecast. 
The forecast will be developed using a combination of both a bottom-up (short term) microeconomic
methodology and a top-down macroeconomic methodology. The bottom-up forecast includes a review
of recent industry trends and expectations of future airline service and schedule data. It will incorporate
airline input regarding short-term capacity recovery from COVID-19 as well as input from industry trade
groups such as Airlines For America (A4A), the International Air Transport Association (IATA), and Airports
Council International (ACI). These industry groups provide important context into the recovery at
gateways markets such as Boston, compared to domestic and regional markets. 
Statistical analyses of the relationship between historical demand and local and national economic
conditions will inform the top-down, longer-term forecast. Previously, econometric factors such as U.S.
Gross Domestic Project (GDP), regional GDP, regional total personal income, and the cost of fuel served as
representative independent variables in the regression analysis. Given Boston’s market size and strong
economy, these factors may be used again in the 2022 ESPR aviation demand forecasts. 
It is also important to note that given Logan Airport’s position in the northeast regional market, the trends
and market dynamics at other nearby airports such as Manchester-Boston Regional Airport (MHT) and
Rhode Island T.F. Green International Airport (PVD) will also be considered.

Boston Logan International Airport 2020/2021 EDR 
Introduction/Executive Summary 1-15 
Massport Investment in Logan Airport 
Massport constantly monitors, evaluates and implements enhancements to Logan Airport’s safety,
security, operational efficiency, and accessibility to and from the Boston metropolitan area, while carefully
monitoring the environmental effects of Logan Airport operations. Recent and ongoing terminal area
projects are aimed at providing seamless post-security connectivity among the terminals along with
enhancements to passenger processing through consolidated security checking areas. Access to and
around Logan Airport also remains a priority. Massport continues to work with FAA to enhance airside
safety through a variety of runway safety area (RSA) improvements and simplification of the airfield
geometry. 
As noted above, the impacts of the COVID-19 pandemic have precipitated a wide range of changes at
Logan Airport. Both the drop in passengers and associated revenues in 2020 and 2021 required significant
adjustments to services and project schedules. Massport has focused on adjusting services to match the
shifting passenger levels and ensure that those changes are made with careful consideration of managing
environmental and operating impacts. In some areas, programs have been adjusted to reflect current
needs and impacts. Massport remains committed to implementing project-related mitigation strategies,
as documented in Chapter 9, Environmentally Beneficial Measures and Project Mitigation Tracking . 
2020 and 2021 Highlights and Key Findings 
This section provides a brief overview of key findings, by chapter, at Logan Airport in 2020 and 2021.
Additional information concerning Airport activities is provided in subsequent chapters. This section also
highlights Massport’s efforts to further sustainability through specific projects and initiatives with a 
sustainability leaf and summarizes Massport’s sustainability program. 
The Secretary’s Certificate on the 2018/2019 EDR , which formed the Scope of this 2020/2021 EDR ,
acknowledged that activity levels and operations have decreased due to the COVID-19 pandemic. Given
the anomaly of this reporting timeframe, MEPA directed that a combined 2020 and 2021 EDR be filed to
provide a clearer indication of post-pandemic growth trends, along with a methodology for the
forthcoming future forecast. 
As of the filing of this 2020/2021 EDR , Logan Airport continues to recover from reduction in demand from
the COVID-19 pandemic. The effects of COVID-19 on the aviation industry and Logan Airport continue to
evolve. As a result, the 2022 ESPR will provide an updated forecast, reflecting continuing recovery from
the pandemic as well as industry changes that are reshaping aviation in the U.S. and internationally. 
Activity Levels 
Until the onset of the COVID-19 pandemic, Logan Airport (and the aviation industry in general) had been
experiencing strong growth, largely driven by the positive economic conditions in the Boston region, low
unemployment, a strong, diverse economic base, and continued investment in commercial and residential
real estate, particularly in life sciences, finance, healthcare, and higher education. Due to the COVID-19
pandemic, 2020 passenger levels and operations have dramatically decreased, with 2021 passenger levels
showing a gradual return towards 2019 levels.

Boston Logan International Airport 2020/2021 EDR 
Introduction/Executive Summary 1-16 
Consistent with the rest of the U.S. airport industry, Logan Airport experienced steep declines in airline
activity and passenger volumes over the past two years. Different states and different regions within the
U.S. have differed in their response to COVID-19 restrictions which in turn reflected the willingness of
consumers to resume travel to and from particular markets. The net result is that air travel recovery at
Logan Airport is a work in progress. Logan Airport has been recovering at a slower rate when compared to
the overall U.S. scheduled passenger recovery, which recovered 72.7 percent of its 2019 levels in 2021. 15 
Prior to the pandemic, Logan Airport had been averaging an annual passenger growth of 5.1 percent
since 2014, and was previously outpacing the overall U.S. passenger growth of 4.0 percent per year for the
same time period. 
In 2020, the domestic passenger market declined by 68.5 percent to 10.7 million compared to 2019 but
rebounded in 2021 to 20.0 million passengers compared to 2020, which represents about 58.8 percent of
2019 annual domestic passenger levels. Although domestic passenger activity reached a record peak of
34.1 million in 2019, 2021 domestic passenger activity levels were below levels seen prior to 1998. 
The total number of aircraft operations at Logan Airport declined by 51.6 percent, from 427,176
operations in 2019, which was a historic peak since 2001, to 206,702 operations in 2020. Operations then
increased in 2021 to 266,034 operations, representing a recovery of 62.3 percent of 2019 levels. 
Please see Chapter 2, Activity Levels, for additional information. 
Airport Planning 
Massport is continually improving the facilities at Logan Airport to accommodate changes in passenger
demand, aircraft activity, cargo needs, and transportation access. In Chapter 3, Airport Planning , Massport
has identified priority planning projects and initiatives in the following categories: 
 Ground Transportation and Parking; 
 Terminals; 
 Airside Planning; 
 Service Areas; 
 Airport Buffers and Open Space; and 
 Energy, Sustainability, and Resiliency. 
As a result of this significant reduction in Airport activity and dramatic reduction in revenues through
2020 and 2021, Massport, airlines, and other Logan Airport tenants necessarily adjusted their operations.
The schedule for a number of Massport’s and tenant Airport projects and programs were also adjusted.
Massport continues to review the status of its projects/programs, and additional changes or deferments
continue to occur in response to activity levels and revenues. Of particular note is careful and continuing
review of Logan’s ground access programs to remain aligned with ridership levels and long-standing
high-occupancy vehicle (HOV) transportation services. Despite these challenges, Massport remains
committed to implementing project-related mitigation strategies.

Introduction/Executive Summary 1-17 
Several projects aimed at providing on-Airport roadway congestion relief are ongoing and are expected
to be complete by summer 2023, namely: 
 On-Airport roadway improvements to enhance efficiency and reduce congestion, 
 Roadway and curb improvements in front of Terminal C (Arrival and Departure levels) to reduce
peak hour congestion and prioritize HOV access, 
 Relocation of the RideApp traffic for Terminal B from the Central Garage to the Departures level
of Terminal B, 
 Construction of roadways exiting the Terminal B departures level that will allow traffic to exit in
its own lane, rather than merging with traffic destined for Terminals C and E, 
 Installation of a tunnel exiting the Terminal B garage that will allow traffic to exit in its own lane
on the Arrivals level, rather than merging with traffic destined for Terminals C and E, and 
 Improvements to the roadways connecting Terminals B and C to improve circulation, reduce
congestion, and improve safety. 
Recent and ongoing terminal area projects are providing seamless post-security connectivity and
flexibility among the terminals along with enhancements to passenger processing through consolidated
security checking areas. 
To enhance the on-Airport roadway network, Massport is improving several of the terminal area roadway
segments and intersections. In December 2019, Massport relocated most RideApp drop-off and pick-up
areas in the Central Garage. 
Since filing the 2018/2019 EDR , Massport has completed state and/or federal environmental review of
several projects: 
 Logan Airport Parking Project , which will add 5,000 commercial parking spaces at Logan Airport
in locations already in use for parking. The additional parking spaces respond to the MassDOT
and U.S. Environmental Protection Agency (EPA)’s approval of a modification to the regulatory
Logan Airport Parking Freeze. 16 The additional spaces are intended to reduce environmentally
harmful drop-off/pick-up modes (i.e., dropped off or picked up by private vehicles, taxi, RideApp,
or black car limousine service). The joint MEPA/NEPA review process was completed in January
2020. This project is currently deferred due to the reduction in passenger activity associated with
the COVID-19 pandemic. 
 Terminal C Canopy, Connector and Roadway Project received federal environmental approval
under NEPA in November 2018. As described in the 2017 ESPR , construction of this project will
replace and reconfigure sections of the elevated roadways connecting Terminals B and C.
Construction of the replacement canopy was completed in 2021, with a slightly reduced program
than originally planned. The Terminal C to B Connector was completed in 2022 and roadways are
anticipated to be complete in summer 2023. 
 Runway 9-27 RSA Improvement Project , which includes construction of a deck with an
Engineered Materials Arresting System (EMAS) on the end of Runway 27, to meet FAA safety 
16 310 Code of Massachusetts Regulations 7.30 and 40 Code of Federal Regulations 52.1120.

Regional Transportation 
In 2020, air passenger activity in the New England region declined significantly with some recovery in
2021. By year-end 2021, regional air passengers recovered to about 56 percent of 2019 levels. Prior to the
pandemic, nearly 60 million air passengers flew through the New England system in 2019, a historic high.
The 10 regional airports (excluding Logan Airport) in New England accommodated approximately 6 and
11 million air passengers in 2020 and 2021, respectively, compared to approximately 17.2 million
passengers in 2019. 
In 2021, Bradley International (BDL), Rhode Island T.F. Green International (PVD), Portland International
Jetport (PWM), Bangor International (BGR), Manchester-Boston Regional (MHT), Worcester Regional
(ORH), and Hanscom Field (BED) recovered between approximately 80 to 100 percent of their 2019 total
aircraft operations. Whereas, Tweed-New Haven (HVN), Burlington International (BTV), and Portsmouth
International (PSM) airports exceeded 2019 operation levels, fueled in part by charter and general aviation
(GA) activity growth. Commercial passenger service recovery continues to lag at all regional airports,
however, several airports welcomed new entrant services in 2020 and 2021 offered by low-cost and
ultra-low-cost carriers such as Allegiant Air, Avelo Airlines, Breeze Airways, Frontier Airlines, and Sun
Country Airlines. 
According to the latest statewide airport economic impact study from 2019, Massport’s three airports,
Logan Airport, Worcester Regional Airport, and Hanscom Field, made significant contributions to the
regional economy, generating approximately $23.1 billion annually, or 94 percent of the overall economic
benefits generated by the Massachusetts’ airport system. 17 Hanscom Field is a reliever airport to Logan
Airport and is the second busiest airport in New England. 
Passenger activity levels at Worcester Regional Airport declined by approximately 78 percent in 2020
compared to 2019, followed by further decline in 2021 when all commercial traffic was temporarily
suspended. Altogether, Worcester Regional Airport has reported a total of nearly 890,000 cumulative
passengers since 2013 when it re-introduced commercial services. jetBlue Airways, American Airlines, and
Delta Air Lines have resumed nonstop flights to the majority of its pre-pandemic served destinations as of
the end of 2021. Massport continues to invest in Worcester Regional Airport—together with the City of
Worcester, Massport has already initiated a $100 million, 10-year investment to revitalize and attract
commercial operations to Worcester Regional Airport. In November 2022, Massport celebrated the 1
millionth passenger to use Worcester Regional Airport since the resumption of passenger service in 2013. 
In response to COVID-19, American Airlines, Delta Air Lines, and jetBlue Airways temporarily suspended
service in and out of the Worcester Regional Airport between October 2020 and July 2021. By August

Introduction/Executive Summary 1-19 
2021, Worcester Regional Airport welcomed back nonstop service to New York John F. Kennedy
International Airport (JFK), which grew to twice daily by December 2021. jetBlue Airways also restarted
operations to Fort Lauderdale in October 2021. American Airlines and Delta Air Lines re-commenced daily
service to New York LaGuardia and Philadelphia, respectively, in November 2021. Although Delta Air Lines
previously operated flights to its hub in Detroit prior to the pandemic, according to published OAG
schedules, 18 no nonstop service between the two airports remains. 
Amtrak rail system-wide ridership decreased from 16.8 million customer trips in fiscal year (FY) 2020 to
12.2 million trips in FY 2021. In FY 2020, the Northeast Corridor (NEC) carried approximately 6.1 million
passengers, down approximately 51 percent from the prior year. In FY 2021, the NEC carried 4.4 million
passengers on those services, down about 28 percent from the prior year. 
Ground Access 
Post pandemic, it is anticipated that Logan Airport will continue to be one of the leading airports in the
United States in terms of HOV and transit mode share. Massport remains committed to promoting
numerous HOV, transit, and shared-ride options to improve on-Airport roadway and curbside operations,
alleviate constraints on parking, and improve customer service. Key findings from 2020 and 2021 are
summarized in the bullets that follow and additional details can be found in Chapter 5, Ground Access to
and from Logan Airport. 
 Average weekday on-Airport vehicle miles traveled (VMT) decreased by about 75 percent from 2019
to 2020. Average weekday on-Airport VMT increased from 2020 to 2021. The change in average
daily traffic in 2021 can be attributed primarily to a post lock-down rebound in air passenger
activity, increase in passenger drop-off/pick-up, cargo, and non-aviation related Airport uses. Based
on more recent data, Airport activity and on-Airport VMT is trending higher in 2022 due to the
reduction in air travel restrictions and social distancing impacts of COVID-19. 
 RideApp transactions dropped significantly from more than 7 million in 2019 to just over 2 million in
2020 due to travel restrictions from COVID-19 and potential health safety concerns associated with
sharing vehicles. As passenger levels increased in 2021, the number of rideshare users also
increased. However, the number of riders is still significantly lower than pre-COVID (2019 and prior)
levels. Due to the impacts of COVID-19, the number of black car limousines and scheduled van seats
coming to the Airport dropped by nearly 64 percent from 2019 to 2021. Taxi dispatches declined 80
percent in 2020 compared to 2019 but increased between 2020 and 2021. The Massachusetts Bay
Transportation Authority (MBTA) Blue Line ridership decreased by approximately 58 percent
between 2019 and 2020 and increased in 2021 compared to 2020. 
 Massport has a goal of reaching 35.5 percent HOV mode share by 2022 and 40 percent by 2027.
Based on the results of the 2019 Logan International Airport Air Passenger Ground-Access Survey ,
HOV mode share reached 40.4 percent, exceeding both near-term and longer-term goals. COVID-19
has had a range of impacts on ground transportation, particularly on the use of ground-access HOV
modes. While it is anticipated that the HOV mode share will drop as a result of COVID-19 over the
short term, Massport remains committed to meeting the HOV mode share goals going forward.
Results of the 2022 Air Passenger Ground-Access Survey will be presented in the 2022 ESPR . 
18 Published schedules as of September 2022.

Introduction/Executive Summary 1-20 
Ground Access Strategy 
Massport has a long-standing multi-pronged, trip reduction strategy to diversify and enhance ground
transportation options for passengers and employees traveling to and from Logan Airport. The strategy is
designed to offer passengers a choice of HOV, transit, and shared-ride options that are convenient and
reliable, and that reduce environmental and community impacts. 
Massport’s strategy also aims to provide sufficient on-Airport parking for air passengers choosing
automobile access modes and/or who have limited HOV options. In 2017, the Massachusetts Department
of Environmental Protection (MassDEP) amended the Logan Airport Parking Freeze to allow for an
increase of up to 5,000 on-Airport commercial parking spaces, which allows for the construction of
additional parking to reduce the use of drop-off/pick up modes and alleviate constrained on-Airport
parking conditions. In January 2020, Massport received the FEIR certificate from the Secretary of the EEA,
completing the environmental review process for the construction of 5,000 additional parking spaces.
While the project has completed the environmental review process, construction of these additional
parking spaces has been deferred until passenger activity levels recover sufficiently. The 2022 ESPR will
provide an updated project status. 
A long-standing Massport interest is addressing on-Airport roadway congestion with a combination of
policy changes and infrastructure improvements. Alleviating terminal area congestion is important for
continued safe and efficient landside operations and to reduce environmental impacts. Enhancing
multimodal transportation options and providing modern, flexible infrastructure is one way an airport can
reduce greenhouse gas (GHG) emissions and improve its environmental footprint. 
Massport recognizes the importance of providing safe and reliable HOV services to and from the Airport
and has a HOV mode share goal of reaching 40 percent by 2027. Understanding the growth in RideApp
use and their impact on regional and terminal area roadway congestion is essential to managing
on-Airport traffic volume and promoting HOV services as a viable and attractive alternative. To address
congestion issues caused by RideApps prior to the pandemic, Massport reconstructed the ground floor of
the Central/West garage to facilitate passenger drop-off (between the hours of 10:00 AM and midnight)
and pick-up (all times). This service change was completed in December 2019. 
During 2020 and 2021, the pandemic effects resulted in fewer passengers and employees traveling to and
from Logan Airport and less roadway congestion both in Boston and the metropolitan area. In addition,
the public’s interest in using HOV transportation services like buses, rapid transit, and commuter rail, is
still diminished by concerns about COVID-19, reduced service, or service disruptions. Within that context,
Massport continues to evaluate and plan for the recovery of air passenger activity and remains committed
to implementing the broad range of ground access and trip reduction strategies. Massport continues to
carefully review both on and off-Airport activity levels and will adjust its ground access programs to align
with air passenger levels. The schedule for HOV and ground access improvements have and will continue
to be adjusted due to current conditions. Future EDRs and ESPRs will provide detailed updates on all
service adjustments and activity levels. 
Massport continuously evaluates its strategies and programs aimed at improving and, where needed,
expanding HOV services to and from Logan Airport, including continued investment in Logan Express
facilities and service. The initiatives described below can improve roadway operations as well as air quality
emissions. The following measures have been implemented or remain under consideration:

Boston Logan International Airport 2020/2021 EDR 
Introduction/Executive Summary 1-21 
 Continuing to promote Logan Express ridership by expanding parking, frequency, and facility
upgrades. 
 Suburban Logan Express Service Enhancements 
▪ Increase Braintree Logan Express service from two to three trips per hour (implemented in 
May 2019 but reduced to hourly service in March 2020 due to the impacts of COVID-19.
In July 2021, service resumed to every half hour service). 
▪ Add about 1,000 additional spaces to the Framingham garage (permitting completed in
2020; however construction is deferred). 
▪ Marketing to support Logan Express strategy and increase ridership. 
▪ Implement Logan Express electronic ticketing (completed in March 2021). 
▪ Evaluate new Logan Express suburban locations, with a plan to open at least one new site.
Peabody Logan Express relocated in February 2022. Massport is evaluating opportunities
for further expansion of capacity and service. 
▪ Explore RideApp Last Mile connections. 
▪ Continue to monitor parking capacity at all Logan Express sites. 
 MBTA Silver Line 
▪ Massport continues its partnership with the MBTA to offer free Silver Line boardings at 
the Airport. The reduced dwell times and faster travel times through the terminal area led
Massport to extend the free-fare program indefinitely. Eight Silver Line buses purchased
by Massport are operated by the MBTA with Massport paying operating costs for the
Silver Line buses. In 2018, Massport funded mid-life rebuilds of four Silver Line buses.
Massport will purchase eight new Silver Line buses as part of a forthcoming (2023) MBTA
procurement. 
 Urban Logan Express Service 
▪ Change pick-up/drop-off location from Copley to Back Bay Station (implemented in 
2019). 
▪ Discount one-way fare from $7.50 to $3.00 (implemented in 2019). 
▪ Provide free service from Logan Airport (implemented in early 2019). 
▪ Provide security line priority status to Logan Express Back Bay riders (implemented in
2019; this service was temporarily suspended due to COVID-19, but restored in October
2022). 
▪ Marketing campaign to support increased ridership (ongoing). 
▪ Implement Logan Express electronic ticketing (implemented upon reopening in October
2022). 
▪ Explore a second urban Logan Express service. 
 RideApp Management Plan 
▪ Facilitate rematch and shared ride by moving RideApp drop-off/pick-up activity to new
dedicated areas in the Central Garage (complete).

▪ Adopt new RideApp fee structure to support HOV strategies, encourage shared rides, and
reduce gateway congestion (complete). 
▪ Optimize RideApp operations on-Airport through data reporting, enforcement tools, and
emerging RideApp products (continuing). 
 Infrastructure improvements 
▪ Massport will continue to evaluate and identify the need for additional infrastructure
modifications as a complement to policy changes to allow terminal area roadways and
curbsides to continue functioning adequately and minimize vehicle idling and associated
emissions. Changes will be implemented as needed. 
Noise 
Massport strives to minimize the noise effects of Logan Airport operations on its neighbors through a
variety of noise abatement programs, procedures, studies, 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 (NOMS); extensive residential and school sound
insulation programs; time-of-day and runway restrictions for noisier aircraft; ground run-up procedures;
and flight tracks designed to optimize over-water operations (especially during nighttime hours). The
public can register noise complaints by phone or online through Massport’s website. 20 
Key findings are summarized in the bullets that follow and additional details can be found in Chapter 6, 
Noise Abatement. 
 Massport continues to seek funding for noise mitigation of properties that are eligible to
participate in its Residential Sound Insulation Program (RSIP). In 2021, Massport updated its Noise
Exposure Map (NEM) and is initiating a new program to sound insulate eligible homes and re-
evaluate sound insulation in homes treated prior to 1993. To date, Massport has provided sound
insulation for a total of 36 schools and 11,515 residential units with over $170 million invested
since the start of the program. 
 Massport is currently working with FAA to possibly address issues with the first-generation sound
insulation windows. In January 2020, Massport’s Chief Executive Officer (CEO) sent a letter to the
FAA Associate Administrator requesting that Massport and FAA work together to address re-
treatment of homes that were sound insulated during the early years of the program to upgrade
eligible homes to newer, more effective and durable materials. The Associate Administrator
responded that FAA is exploring limited circumstances under which Massport might be able to

Introduction/Executive Summary 1-23 
mitigate homes that had been mitigated before FAA first issued sound insulation standards in
1993. The first step in this process was for Massport to submit an updated RSIP NEM. FAA
accepted the 2020 NEM on December 20, 2021 that was submitted by Massport and Massport is
in the process of re-starting its RSIP. Massport selected a consulting team that will survey eligible
program areas to identify potentially eligible properties that meet the FAA’s new criteria for a
pilot program. In 2022, Massport applied for and was approved for an initial grant by the FAA to
fund the beginning phase of the new RSIP program. Please see Appendix H, Noise Abatement for
additional information. 
 The fleet mix of Logan Airport continues to be composed of aircraft types with the quietest
available technology (Stage 5 is the quietest). About 29 percent of 2020 and 2021 operations
were conducted in aircraft meeting the requirements for Stage 5 certification, 69 percent meeting
Stage 4 certification, and the remaining 2 to 3 percent meeting only Stage 3 certification. Due to
the pandemic, several airlines accelerated the retirement of older, louder, and less efficient aircraft
models such as the Airbus A330-200/300 and A340, Boeing 747, 757, and 767, McDonnell
Douglas MD-88, Embraer 190, and the smaller Bombardier CRJ200 regional jet (RJ). The effects of
the airline fleet changes on the Logan Airport noise environment started to be seen in 2021 and
should be more apparent in following years. 
 Massport completed a multi-year effort with Massachusetts Institute of Technology (MIT) and
FAA to identify opportunities to reduce noise through changes to performance-based navigation
(PBN) procedures and flight performance modifications. This is a first-in-the-nation project
between the FAA and an airport operator to better understand the implications of PBN and
evaluate strategies to address community concerns. 
 Nighttime operations represented approximately 13 percent of total operations in both 2020 and
2021. Reflecting the overall drop in operations, total nighttime flights (commercial and cargo)
decreased from an average of 195 per night in 2019 to 76 per night in 2020 and 98 per night in
2021. While nighttime operations in commercial passenger aircraft operations decreased,
nighttime cargo operations increased from 2019 to 2020, most likely due to an increased demand
for shipping during the pandemic. Most nighttime operations (about 86 percent in 2020 and 78
percent in 2021), occurred either before midnight or after 5:00 AM. 
 The total number of people residing within the 2020 day-night average sound level (DNL) 65
decibel (dB) contour (804 people) represents a decrease of almost 91 percent compared to the
2019 estimate (8,665 people). The 2021 population estimate within the DNL 65 contour totaled
2,497 people, which is about 29 percent of 2019. The primary factor affecting the size of the DNL
contours is the reduced number of aircraft operations. 
 The 2021 DNL contours are similar in shape to the 2019 DNL contours but reduced in size due to
the reduction in operations. The 2020 DNL contours have a slightly different shape and are
slightly smaller than 2021 over East Boston and Winthrop. The population within the 2020 DNL 65
dB contour is mainly located in Revere, Winthrop (Point Shirley) and Boston (Orient Heights).
Compared to 2020, the 2021 DNL contour includes more homes, and therefore greater
population, in each of those areas, as well as some in East Boston (Eagle Hill).

Boston Logan International Airport 2020/2021 EDR 
Introduction/Executive Summary 1-24 
Noise Strategy 
The foundation of Massport’s noise program is the Logan Airport Noise Abatement Rules and Regulations 21 
(Noise Rules), which have been in effect since 1986. Massport’s Noise Abatement Office is responsible for
implementing noise abatement measures and generally monitoring community complaints and other
aspects of the noise effects from Logan Airport operations. 
Massport is focused on the following noise abatement initiatives: 
 Partnerships with Airlines and FAA 
▪ Massport is encouraging retrofitting the
Airbus A319/320/321 family of aircraft with
vortex generators, which reduce tonal noise
on approach. In October 2018, jetBlue
Airways (the air carrier with the greatest
number of operations at Logan Airport)
announced plans to retrofit its older Airbus
fleet with Vortex Generators. This move
reflects the partnership between Massport
and the airlines to reduce aircraft noise to
benefit surrounding communities. As 
airlines retrofit aircraft and transition to the newer models of the A320 family, the number
of aircraft operating at Logan Airport without the vortex generators is expected to
decrease. 
▪ On October 7, 2016, Massport and FAA signed a Memorandum of Understanding
(MOU) 22 to frame the process for analyzing opportunities to reduce noise through
changes or amendments to PBN, including area navigation (RNAV). 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. MIT is the
technical lead. Block 1 was completed in late 2017 and recommendations were made to
the FAA. MIT completed the Block 2 report, which was released in December 2021. In
January 2022, the Massport CAC put forth two of the procedures for further study and
implementation by FAA. On January 19, 2022, Massport submitted a request to the FAA
for review and implementation of two Block 2 procedures at Logan Airport. 
▪ The fleet operating at Logan Airport is comprised of 69 percent Stage 4 aircraft and
29 percent Stage 5 aircraft (Stage 5 being the quietest), well above the FAA minimum
Stage 3 engines. 
▪ Massport continues to prohibit the use of Runway 4L for departures and Runway 22R for
arrivals from 11:00 PM to 6:00 AM; maximize late-night over-water operations via
Runways 15R and 33L; and restrict nighttime engine run-ups and use of auxiliary power
units (APUs). 
21 The Logan International Airport Noise Abatement Rules and Regulations, effective July 1, 1986, are codified as 740 Code of
Massachusetts Regulations (CMR) 24.00 et seq (also known as the Noise Rules).

Boston Logan International Airport 2020/2021 EDR 
Introduction/Executive Summary 1-25 
▪ Massport continues to encourage the voluntary use of reduced-engine taxiing when
appropriate and safe. 
▪ Massport continues improvement of the NOMS. Massport upgraded the system in 2019
and continues to invest in maintaining the system including installing new field monitors
and infrastructure where needed. The total replacement of noise monitoring equipment
at 29 sites around Logan Airport was completed in August 2021. 
 Sound Insulation Program 
▪ Massport has one of the most extensive residential and school sound insulation programs
in the nation. To date, Massport has installed sound insulation in 5,467 residences,
including 11,515 dwelling units, and 36 schools in East Boston, Roxbury, Dorchester,
Winthrop, Revere, Chelsea, and South Boston. Since the start of the program, over $170
million has been invested. 
▪ Approximately 8 percent of applicants also choose the Room-of-Preference option that
allows the owner to identify a room (usually a bedroom or living room) for extra
acoustical treatment. 
Air Quality/Emissions Reduction 
Prior to the pandemic, total emissions from all sources associated with Logan Airport were less than they
were a decade ago, with the exception of oxides of nitrogen (NOx). This long-term downward trend is
consistent with Massport’s longstanding objective to accommodate the demands of increasing passenger
and cargo activity levels with fewer aircraft operations and reduced emissions wherever possible. 
The reduction in aircraft operations and passenger-related ground access trips in 2020 and 2021 during
the pandemic compared to 2019 resulted in lower emissions of air pollutants for which there are National
Ambient Air Quality Standards (NAAQS), as well as lower emissions of the precursors to the
NAAQS-regulated pollutants, GHG emissions, and hazardous air pollutants (HAPs), than emission levels
estimated for Logan for the years 1999, 2000, and 2010 through 2019. Changes in the 2020 and 2021
emissions are also a result of changes in the aircraft fleet operating at Logan Airport and emission
reduction initiatives by Massport that have reduced emissions. Despite the reduction in the number of
operations and passengers, Massport remains committed to implementing emissions reduction strategies. 
Massport prepared emissions inventories for 2020 and 2021 for the criteria pollutants carbon monoxide
(CO), particulate matter (PM), and volatile organic compounds (VOCs), as well GHGs and NOx. Key findings
of those emissions inventories include: 
 Total 2020 modeled emissions of VOCs, NOX, CO, and PM decreased from 2019 by about 58
percent, 54 percent, 59 percent, and 47 percent, respectively. This is primarily attributable to the
decrease in passenger activity levels and aircraft operations due to the COVID-19 pandemic. 
 The 2021 total modeled emissions of VOC, NOX, CO, and PM decreased by about 45 percent, 42
percent, 48 percent, and 23 percent, respectively, from 2019 levels. Similar to 2020, this is
primarily attributable to the decrease in passenger activity levels and aircraft operations due to
the COVID-19 pandemic.

Boston Logan International Airport 2020/2021 EDR 
Introduction/Executive Summary 1-26 
 GHG emissions associated with Logan Airport in 2020 and 2021 are less than 1 percent of the
most recent statewide total emissions estimates. Total Logan Airport GHG emissions (i.e., Scopes
1, 2, and 3) decreased from 2019 to 2020 by approximately 60 percent but increased from 2020 to
2021. However, 2021 GHG emissions remain below the pre-pandemic emissions of 2019. 
Effect of Aircraft Engine Technology on NOx 
Aircraft emissions continue to represent the largest source (95 percent) of NOx at Logan Airport, with the
remaining comprising of ground service equipment (GSE), other sources and motor vehicles
(approximately 5 percent). Massport does not have any control over aircraft emissions, which represent
the vast majority of total Airport emissions. 
To reduce fuel use and emissions, aircraft engine designers and manufacturers continue to work on
producing more “fuel-efficient” (i.e., less fuel-burning) engines. This is achieved by enhancing engine
performance with improved fuel combustion technologies, greater thrust-generating power, and less
engine wear. Aircraft are also being designed to decrease fuel-burn with advancements in aircraft wing
and body aerodynamics, light-weight alloy materials, and improved means of navigation. These emerging
technologies and reduced fuel burn are expected to reduce emissions, reduce noise, and moderate the
growth in NOx emissions into the future. 
Air Quality Strategy 
Massport’s air quality management strategy for Logan Airport focuses on decreasing emissions from
Airport-related sources, in addition to furthering innovative means to achieve emissions reductions
Airport-wide. Since Massport does not have direct control over aircraft operations or fleet choices of the
airlines, it continues to focus on areas that Massport does control or has an opportunity to influence.
Massport’s air quality management strategy for Logan Airport focuses on decreasing emissions from
Airport-related sources, in addition to furthering innovative means to achieve emissions reductions
Airport-wide. Massport has established a number of goals and objectives to address air emissions from
Airport operations, including the reduction of GSE and Massport vehicle fleet emissions. Massport is
focused on the following initiatives: 
 Net Zero Roadmap 
▪ As discussed below, in 2022, Massport released its Net Zero Roadmap by 2031 , an
Authority-wide emissions reduction strategy, the goal of which is to strive to reach net
zero GHG emissions by 2031 under its direct control, by Massport’s 75 th anniversary. The 
2022 ESPR will report on the implementation of that program, which is summarized in the
Sustainability and Resiliency Program section below. Key pathways to Net Zero include
building energy efficiency, transitioning to electric vehicles, phased procurement of a
sustainable energy supply, and a range of measure to help enable emissions reduction by
our tenants and business partners. 
 Provide infrastructure and encourage practices that support reductions in aircraft emissions 
▪ Massport provides pre-conditioned air (PCA) and 400 Hertz (Hz) power at all aircraft
contact gates to reduce aircraft idling and use of APUs.

Boston Logan International Airport 2020/2021 EDR 
Introduction/Executive Summary 1-27 
▪ Massport encourages single engine taxiing procedures by the airlines when safe, to
reduce both noise and air emissions. 
▪ Installing airside electric charging stations to support the use of battery-powered eGSE
such as aircraft tugs and belt loaders. 
 Maximize use of HOV and reduce single occupancy vehicle trips, particularly drop-off/pick-
up trips, and passenger use of private vehicles to and from the Airport 
▪ Massport implements an extensive HOV strategy and ground transportation
improvements (see previous section, Ground Access Strategy, for details). 
 Reduce emissions from fleets operating at Logan Airport 
▪ Massport is facilitating the replacement of gas- and diesel-powered GSE with all-electric
GSE (eGSE) (as commercially available) by supporting the installation of charging
infrastructure. 
▪ In 2018, Massport was awarded an FAA Voluntary Airport Low Emission (VALE) Program
grant of $1,600,000 for charging infrastructure at Terminal B. Massport contributed
$626,000 in matching funds to install 50 eGSE charging stations. In 2019, through the
same program, Massport was awarded $3,200,000 for charging infrastructure at Terminal
C. Massport contributed $953,000 toward the installation of 42 eGSE charging stations. 
▪ In 2019, Massport, in partnership with jetBlue Airways, was awarded $445,000 through
MassDEP’s Volkswagen Diesel Settlements & Environmental Mitigation Open Solicitation
grant program. The grant, aimed at reducing NOX and GHG emissions, will support the
replacement of 31 pieces of GSE with new eGSE and install four eGSE charging stations at
Terminal C. United Airlines also privately pursued this grant and was awarded $280,000. 
▪ In 2019, Massport was awarded by the EPA under the Diesel Emission Reduction Act
(DERA) a $990,000 grant to replace 44 diesel-powered GSE equipment with all-electric
baggage tractors, belt loaders, and push back tugs. GSE owners at Logan Airport will
contribute a $1,210,000 match. 
▪ In 2020, Massport was awarded a grant through FAA’s VALE for charging infrastructure at
Terminal E and Signature Aviation Building 14 to install 10 eSGE charging stations. 
▪ Massport is collaborating with the Massachusetts Clean Energy Center (MassCEC) to
study opportunities to enable conversion of the ride-for-hire fleet (RideApp, Rental Car
Taxi and limousine vehicles) that serves Logan to transition to electric vehicles. In early
2022, the MassCEC provided a grant to initiate this work and provide some funding to
increase Logan’s electric vehicle (EV) charging infrastructure. 
 Provide infrastructure to support alternative fuels including compressed natural gas (CNG)
and electricity

 In 2020, there were four reportable spills with two storm drains impacted. In 2021, there were four
reportable spills with no storm drains impacted. 
For additional information, please see Chapter 8, Environmental Compliance and Management/Water
Quality. 
Sustainability and Resiliency Program 
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, environmental, 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.
Massport is committed to implementing 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, and which individual chapters of this 
2020/2021 EDR more fully describe, where appropriate.

Introduction/Executive Summary 1-29 
Massport Roadmap to Net Zero 
In March 2022, Massport published its Roadmap to Net Zero by 2031 , an ambitious Authority-wide
program to achieve net zero GHG emissions by 2031 for the facilities under its control (Scope 1 and 2).
This goal would put Massport nearly two decades ahead of the 2050 deadline that many other
organizations have targeted. 2031 will also be the 75 th anniversary of the establishment of the Authority. 
In addition to determinedly reducing the Authority’s emissions to Net Zero, the plan inspires, encourages,
and strives to enable the efforts and innovations of tenants, business partners, and facility users. It
protects the connection the Authority provides linking Massachusetts and New England to the wider
world. It strengthens and deepens the role it plays as a regional economic engine. Additionally, it is
directly aimed at reducing impacts on our neighboring communities. Massport is exploring five main
pathways to reach net zero: 
 Energy conservation and efficiency 
 Clean and renewable energy sources 
 Sustainable ground transportation 
 Partnerships 
 Culture of sustainability and innovation 
Additional information can be found at 
https://www.massport.com/massport/about- 
massport/roadmap-to-net-zero/ . 
In fall 2022, Massport established a Program Management
Office (PMO) to help advance Roadmap to Net Zero by 2031 
implementation. The 2022 ESPR will provide updates on
program status. 
Logan Airport Sustainability Management Plan (SMP) 
In 2013, Massport was awarded a grant by FAA to prepare a SMP for Logan Airport. The planning effort,
culminating in 2015, holistically addressed sustainability, including considerations for economic vitality,
operational efficiency, natural resource conservation, and social responsibility. The Logan Airport SMP
developed a framework and established an implementation plan with key performance indicators
designed to track airport-wide progress through 2020. 
Massport is currently advancing a series of initiatives to help reach its goals (see Table 1-1 ) in the areas of
(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. 
Each year since the publication of the Logan Airport SMP, Massport has continued to widen the lens of its
sustainability and resiliency goals to incorporate its other aviation and maratime facilities. During 2020

Boston Logan International Airport 2020/2021 EDR 
Introduction/Executive Summary 1-30 
and 2021, Massport also sought new avenues to be a better neighbor to surrounding communities—
reducing noise and air pollution, improving ground access to Logan Airport, and extending Diversity,
Equity & Inclusion (DE&I) initiatives beyond its operational borders. Massport reports its progress towards
achieving each goal, including changes in related performance, in sustainability reports. They highlight
Massport’s progress towards improving sustainability and enhancing resiliency at its facilities. The last
published Annual Sustainability and Resiliency Report , was released in 2019 and can also be found at: 
http://www.massport.com/massport/business/capital-improvements/sustainability/sustainability- 
management/ . 
A new report is forthcoming in 2022, which will outline performance throughout the global pandemic in
fiscal years 2020 and 2021 and serve to close out the performance targets from the 2015 SMP. Massport
looks ahead to announcing updated measurement and verification metrics in its pursuit of net zero
emissions.

Introduction/Executive Summary 1-35 
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 infrastructure 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
November 2018. 
Operational aspects of resiliency strategy include the development of Flood Operations Plans for
Logan Airport and Massport maritime facilities. These plans were introduced in 2014 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. Between 2020 and 2021, Massport conducted a tabletop exercises for
Aviation and Maritime in preparation for extreme storm events such as hurricanes. 
Massport reports on progress towards resiliency goals in its annual sustainability reports. Additional
information about Massport’s resiliency programs are available at: 
http://www.massport.com/massport/business/capital-improvements/sustainability/climate-change- 
adaptation-and-resiliency/ . 
Massport Partnerships and Community Support 
Massport has a long-standing commitment to be a good neighbor. Working in concert with government,
community, and civic leaders throughout Massachusetts and New England, Massport is an active
participant in efforts that improve the quality of life for residents living near Massport’s facilities. 
Massport awarded science, technology, engineering, and math (STEM) and memorial scholarships to six
students from Boston neighborhoods in 2021. Each year, high school students are selected to receive two
Diversity STEM Scholarships and the Thomas J. Butler, Deborah Hadden Gray, Donna Rauseo, and Lowell
L. Richards III Memorial Scholarships based on their academic achievements, post-secondary educational
plans, and a demonstrated commitment to community service. Since 2007, Massport has awarded
Diversity STEM Scholarships to 42 students of color who plan to pursue degrees in a STEM field. Since
2011, Massport has awarded the memorial scholarships to 34 students. Massport also provides annual
scholarship grants to local high schools for students in Charlestown, Chelsea, East Boston, South Boston,
Revere, and Winthrop.

Furthermore, in 2020 and 2021, Massport employees continued to participate in community activities
including a children’s winter coat drive, Veterans Day thank you letters, Thanksgiving food drive, and a
children’s backpack drive, among others. 
Lastly, as an engine for economic growth, Massport continually strives to extend economic opportunities
and create equity for diverse people and businesses, internally and in our surrounding communities. 
Open Space/Buffer Program 
Massport has invested in an extensive open space program to enhance the surrounding communities.
Massport initially committed over $15 million for the planning, construction, and maintenance of four
Airport edge buffer areas and two parks along Logan Airport’s perimeter. These buffers include the
Bayswater Embankment Airport Edge Buffer, Navy Fuel Pier Buffer, and the Southwest Service Area
(SWSA) Buffer (Phases I and II). The award-winning Piers Park was completed in 1995 and has since
become part of a network of greenspace that traverses East Boston from the Jeffries Point waterfront,
through Bremen Street Park and the adjacent Massport Greenway Connector to Constitution Beach. 
Adjacent to the current Piers Park, Piers Park Phase II will add approximately 4.2 acres of green space to
the East Boston waterfront upon completion. Permitting for Piers Park II was completed in 2022;
groundbreaking was held in October 2022 with construction scheduled to be complete by the end of
2023. Studies are also underway by the Trustees of Reservations for a Piers Park Phase III, which would
turn an aging pier into a 3.6-acre greenspace including resiliency features to help protect the
neighborhood from flooding and sea level rise. Today, East Boston enjoys 3.3 miles and more than 33
acres of green space developed or managed by Massport, in partnership with and in response to
engagement with the East Boston community. More information can be found in Chapter 3, Airport
Planning .

Introducción/Resumen ejecutivo 
Introducción 
Massachusetts Port Authority (Massport) continúa con su práctica de más de cuatro décadas de brindar un
registro exhaustivo sobre las tendencias medioambientales, el planeamiento de las instalaciones, los niveles de
operaciones y de pasajeros del Aeropuerto Internacional Logan de Boston (Aeropuerto Logan o Aeropuerto) y
los compromisos de mitigación de Massport en este Informe de datos medioambientales (Environmental Data
Report, EDR) del 2020/2021. A petición del secretario de la Oficina Ejecutiva de Asuntos Energéticos y
Medioambientales ( Energy and Environmental Affairs , EEA) de Massachusetts, este EDR del 2020/2021 combina
los datos y el análisis de los años naturales 2020 y 2021. 
En este EDR, se informa sobre los años 2020 y 2021, reflejando los cambios significativos en el Aeropuerto Logan
y en toda la industria de la aviación que ocurrieron como resultado de la pandemia de la COVID-19 en curso.
Massport se ha esforzado por incluir, según la disponibilidad, actualizaciones relevantes hasta el otoño del 2022
cuando las condiciones actuales dieron lugar a cambios en los proyectos o programas que estaban vigentes en
el 2019 y antes. A finales del 2020, el total de operaciones de vuelo se redujo aproximadamente en un 50 % y los
niveles de pasajeros disminuyeron alrededor del 70 % en comparación con el cierre del 2019, cayendo a niveles
de actividad que no se habían visto desde la década de 1970. Sin embargo, las operaciones de las aeronaves
aumentaron en el 2021, con un total de operaciones de vuelo y niveles de pasajeros que se recuperaron hasta
aproximadamente el 62 % y el 53 %, respectivamente, de los niveles del 2019, lo que mostró un retorno gradual
hacia los niveles del 2019. 
Los descensos del tráfico aéreo causados por recesiones económicas y otros «choques», como los sucesos del 11
de septiembre del 2001 y la Gran Recesión (Crisis Financiera Mundial [CFM]) de 2008/2009, han ido seguidos de
ciclos de recuperación gradual, como se muestra en la Figura 1-1 , evidenciados por una recuperación de cinco
años tras los sucesos del 11 de septiembre del 2001 y una recuperación de tres años tras la CFM. A nivel
nacional, como se muestra en la Figura 1-2 , el 80 % de la recuperación de los niveles de demanda de 2019 se
produjo en julio de 2021, ya que las restricciones de viaje se relajaron y las vacunas estuvieron ampliamente
disponibles. En diciembre del 2021, la demanda de pasajeros en los aeropuertos de los EE. UU. se recuperó a
aproximadamente el 83 % de los niveles del 2019. Gran parte de la recuperación restante dependerá del regreso
tanto de los viajes de negocios como de los internacionales, ya que la capacidad nacional en todo los Estados
Unidos ha vuelto casi por completo a los niveles del 2019. La recuperación total también se verá afectada por la
dotación de personal de las aerolíneas. 
Como se muestra en la Figura 1-3 , la demanda en Boston, aunque está cerca de volver al 70 por ciento de los
niveles del 2019 a finales del 2021, se ha retrasado respecto a la demanda nacional entre un 10 y un 15 por
ciento. Esto coincide con los patrones de recuperación de otros mercados urbanos costeros en los que los viajes

EDR del 2020/2021 del Aeropuerto Internacional Logan de Boston 
Introducción/Resumen ejecutivo 1-2 
de negocios y los viajes internacionales han tardado más en volver a los niveles anteriores a la pandemia. Se
espera que los niveles de actividad de los pasajeros internacionales en el Aeropuerto Logan vuelvan en 2022 y
más adelante. 
La COVID-19 está afectando de una manera sin precedentes no solo la industria de la aviación sino la economía
mundial. Mientras que la preocupación inmediata y más apremiante es el costo humano, la COVID-19 ha creado
profundas implicaciones para casi todos los negocios e industrias. El impacto en la aviación ha sido
particularmente grave. La situación cambia a diario y sigue habiendo una incertidumbre considerable en cuanto
al impacto a corto y largo plazo de la pandemia.

Notas: Terminal del Aeropuerto Logan (izquierda) y zona de recogida de equipajes (derecha) durante la pandemia de COVID-19. 
Como resultado de esta significativa reducción en la actividad del Aeropuerto y la dramática reducción de los
ingresos, tanto Massport, las aerolíneas y otros locatarios han tenido que ajustar y reducir sus operaciones en el
2020 y 2021. En respuesta a esto, el cronograma de varios proyectos y programas del Aeropuerto han sido
revisados y retrasados. Para brindar la mayor transparencia posible, en el Capítulo 3, Planeación aeroportuaria, se
incluyen las actualizaciones más recientes del proyecto hasta septiembre de 2022. Los próximos EDR e informes
de situación y planificación medioambiental ( Environmental Status and Planning Reports , ESPR) seguirán
proporcionando actualizaciones, según estén disponibles. En general, Massport sigue evaluando y planificando la
recuperación de las operaciones de las aeronaves y la actividad de los pasajeros aéreos, y sigue comprometida
con la aplicación de la amplia gama de estrategias ambientales y operativas destinadas a reducir los impactos
asociados a las operaciones del Aeropuerto.

(Massachusetts Environmental Policy Act, MEPA). 1 Desde 1979, Massport presenta estos documentos para
informar los efectos medioambientales acumulados de las operaciones y de las actividades del Aeropuerto
Logan. El Aeropuerto Logan es el primer aeropuerto del país para el que se confeccionó una evaluación
medioambiental anual sobre las actividades aeroportuarias y Massport continúa siendo líder en informes
medioambientales. 
Aproximadamente cada cinco años, Massport confecciona un ESPR, que brinda un panorama histórico y
prospectivo del Aeropuerto Logan. Los EDR, que se confeccionan anualmente en los intervalos entre los ESPR,
brindan una revisión histórica de las condiciones medioambientales para el año que se informa en comparación
con el año anterior. Este EDR 2020/2021 sigue al EDR 2018/2019 e informa sobre las condiciones de 2018 y 2019 . 
En el último ESPR, se utilizó el 2017 como año de base. Mientras Massport y toda la industria de la aviación
continúan ajustándose a la evolución de las condiciones operativas, nosotros seguimos evaluando los impactos
actuales y futuros de la pandemia. Cuando es posible, este EDR incluye información relevante y actualizaciones.
Sin embargo, se abordarán proyecciones y análisis más detallados en el próximo ESPR 2022. 
A petición de la Secretaria tras su revisión del EDR 2018/2019 , se ordenó a Massport que preparara este EDR
2020/2021 combinado y su alcance fue establecido por la certificación del secretario sobre el EDR 2018/2019 de
fecha 19 de marzo de 2021, que se incluye en el Apéndice A, Certificaciones y respuestas a los comentarios de la
MEPA . Este EDR cumple todos los requisitos establecidos en la certificación del secretario en el ESPR 2018/2019, 
incluye respuestas a los comentarios en la certificación del secretario, y actualiza y compara los datos
presentados en el EDR 2018/2019 sobre los siguientes temas: 
Para mejorar la utilidad de este EDR como documento de referencia para los revisores, este informe también
presenta datos históricos sobre las condiciones medioambientales en el Aeropuerto Logan desde 1990, en las
instancias en que hay información histórica disponible. Cuando corresponde y está disponible, este EDR también
incluye actualizaciones hasta el otoño del 2022.

Proceso de revisión medioambiental del Aeropuerto Logan 
Este EDR del 2020/2021 es la próxima presentación de Massport en su proceso de revisión medioambiental
estatal formal, único, pero bien consolidado, que evalúa los impactos medioambientales acumulados del
Aeropuerto Logan. Los documentos brindan un contexto actual e histórico frente al cual los proyectos
individuales del Aeropuerto Logan que alcanzan umbrales de revisión medioambiental estatales y federales se
evalúan sobre las bases de proyectos específicos. A continuación, se describen los procesos de revisión
medioambiental específicos del proyecto para todo el Aeropuerto. 
Contexto histórico para el proceso de EDR/ESPR del Aeropuerto Logan 
En 1979, el secretario de la EEA emitió un certificado solicitando a Massport que defina, evalúe y divulgue cada
tres años el impacto del crecimiento a largo plazo del Aeropuerto a través de un Informe de impactos
medioambientales genérico (Generic Environmental Impact Report, GEIR). En el certificado también se solicitaron
actualizaciones anuales provisorias para brindar datos sobre las condiciones para los años entre los GEIR. El GEIR
evolucionó hasta transformarse en una herramienta de planificación eficaz para Massport y brindó proyecciones
de condiciones medioambientales para que los efectos acumulados de los proyectos individuales se puedan
evaluar dentro de un contexto más amplio. 
La EEA eliminó los GEIR después de las revisiones de 1998 para sus reglamentaciones de la MEPA. Sin embargo,
la certificación del secretario sobre la actualización anual de 1997 2 propuso un proceso de análisis
medioambiental revisado para el Aeropuerto Logan lo que dio como resultado la confección de los EDR/ESPR de
Massport subsiguientes. El EPRS más amplio brinda un análisis de largo alcance de las operaciones, de los

Introducción/Resumen ejecutivo 1-7 
pasajeros y de los impactos acumulativos, mientras que los EDR se confeccionan anualmente para brindar una
revisión de las condiciones medioambientales para el año que se informa en comparación con el año anterior. Se
desarrolló el proceso del EDR/ESPR para permitir que se analicen los proyectos individuales en el Aeropuerto
Logan en un contexto más amplio en todo el Aeropuerto. Como se estableció en la introducción del ESPR de
1999, “mientras que el ESPR y el EDR de Logan brindan el contexto amplio de la planificación para los proyectos
propuestos para el Aeropuerto Logan y los conceptos de planificación futuros que Massport analiza, no se puede
crear ningún proyecto sólido en las bases de inclusión y análisis en el ESPR de 1999” . Luego, establece que los
proyectos que cumplen con los umbrales de revisión de la MEPA o Ley Nacional de Políticas Medioambientales
(National Environmental Policy Act, NEPA) deben someterse a estos procesos, si es necesario. En resumen, los
EDR/ESPR brindan un contexto de planificación acumulada que complementa las presentaciones individuales
específicas del proyecto. 
En el 2018 y 2019, si bien los niveles de pasajeros tuvieron un crecimiento significativo y alcanzaron nuevos
niveles máximos, las operaciones de las aeronaves y los efectos medioambientales asociados se mantuvieron
bien por debajo de los niveles analizados previamente para el Aeropuerto Logan. Por lo tanto, el crecimiento de
la aviación pronosticado presentado en el ESPR del 2004, la afirmación sobre la que se estableció inicialmente el
cronograma del ESPR, no se produjo. En consecuencia, con la aprobación del secretario, Massport confeccionó
los EDR del 2009 y del 2010 en lugar del ESPR originalmente planeado para el 2009. El ESPR del 2011, presentado
a principios del 2013, informó sobre el año natural del 2011 y los pronósticos de los niveles actualizados de las
actividades de los pasajeros y de las operaciones de las aeronaves. El EDR del 2012/2013 conjunto presentó
condiciones para ambos años naturales, 2012 y 2013. En el EDR del 2014, el EDR del 2015 y el EDR del 2016 se
presentaron las condiciones para los años naturales del 2014, 2015 y 2016. Del mismo modo, con el fuerte
crecimiento de pasajeros y la evolución de las tendencias de acceso terrestre con la industria emergente de las
aplicaciones de transporte en coche (antes denominadas empresas de redes de transporte [transportation
network companies, TNC]), la EEA permitió a Massport aplazar el ESPR del 2016 . 
El ESPR del 2017 proporcionó un análisis integral acumulado de los niveles de actividad y de las condiciones
medioambientales para el 2017 y un horizonte de planeación futura. En el ESPR, Massport propuso confeccionar
un EDR del 2018/2019 conjunto para informar los efectos de todas las actividades del Aeropuerto Logan basadas
en la actividad de pasajeros y en las operaciones de las aeronaves reales en el 2018 y 2019. Como se señaló
anteriormente, debido a la pandemia de COVID-19, el Secretario exigió a Massport que presentara un EDR del
2020/2021 combinado para comenzar a evaluar las tendencias de crecimiento posteriores a la pandemia. 
Aunque este informe se centra en gran medida en los años 2020 y 2021, Massport ha anotado los puntos
destacados de recuperación preliminares que se evaluarán con más detalle en el ESPR del 2022. Si corresponde,
Massport continuará identificando y abordando cualquier tendencia de aviación y medioambiental a largo plazo
tanto en los EDR como en los ESPR. 
Revisión específica del proyecto 
Aunque esta revisión de todo el Aeropuerto brinda el contexto de planificación más amplio para los proyectos
propuestos y para los conceptos de planificación futuros, determinados proyectos del Aeropuerto también están
sujetos al proceso público de revisión medioambiental específico del proyecto cuando cumplen los umbrales de
revisión medioambiental estatal. Cuando se requiere, los locatarios de Massport y del Aeropuerto presentan

EDR del 2020/2021 del Aeropuerto Internacional Logan de Boston 
Introducción/Resumen ejecutivo 1-8 
formularios de notificación ambiental (Environmental Notification Forms, ENF) e informes de impacto ambiental
(Environmental Impact Reports, EIR) de conformidad con la MEPA. De manera similar, cuando se desencadena la
revisión medioambiental de la NEPA, se revisan los proyectos de acuerdo con el proceso de revisión
medioambiental de la NEPA. 3 
Massport entiende que la MEPA modificó su reglamento en 301 CMR 11.00 a partir del 24 de diciembre de 2021.
Además, la MEPA publicó el Protocolo Provisional de la MEPA sobre Adaptación y Resiliencia al Cambio Climático ,
en vigencia para todas las nuevas presentaciones a partir del 1 de octubre de 2021, y el Protocolo de
Participación Pública para las Poblaciones de Justicia Medioambiental de la MEPA y el Protocolo Provisional de la
MEPA para el Análisis de los Impactos del Proyecto en las Poblaciones de Justicia Medioambiental , en vigencia para
todas las nuevas presentaciones a partir del 1 de enero de 2022. Todos los proyectos del Aeropuerto Logan que
se presenten ante la MEPA cumplirán con estas normas y protocolos modificados. En los futuros EDR y ESPR, se
documentarán los compromisos de mitigación de sus proyectos que apoyan estas actualizaciones en el capítulo
9, Medidas beneficiosas para el medioambiente y seguimiento de la mitigación del proyecto 
Los proyectos actuales y futuros potenciales que se prevé que se sometan a la revisión de conformidad con la
MEPA y/o NEPA se analizan en el Capítulo 3, Planeación aeroportuaria. 
Divulgación del EDR de 2020/2021 
Aunque los EDR y ESPR no son proyectos sujetos al Protocolo de Participación Pública de la MEPA para
Poblaciones de Justicia Ambiental , Massport reconoce la importancia de un robusto enfoque de divulgación para
asegurar que la comunidad conozca estos informes y tenga la oportunidad de revisarlos y hacer comentarios. La
lista de distribución de los informes EDR y ESPR se actualiza periódicamente para incluir a numerosas
organizaciones, residentes y organismos que han expresado su interés en estos informes. Además, el Resumen
Ejecutivo se ha traducido y continuará siendo traducido al español. 
Sin embargo, a la luz del Protocolo de Participación Pública de la MEPA para las Poblaciones de Justicia
Medioambiental , Massport se ha embarcado en un proceso de divulgación ampliado para este EDR de
2020/2021 , y tiene la intención de seguir desarrollando su enfoque de divulgación para futuras presentaciones. 
Se implementaron las siguientes medidas para esta presentación: 
 Publicar un anuncio en las redes sociales notificando a la
comunidad sobre la próxima presentación. 
 Distribuir el EDR de 2020/2021 electrónicamente a la Lista de
Referencia de Justicia Medioambiental (Environmental Justice,
EJ) proporcionada por la MEPA para el reciente Proyecto de
Mejora de la Zona de Seguridad de la Pista 9-27 de Massport.

Contexto de la planificación del Aeropuerto Logan 
El Aeropuerto Logan cumple una función clave en las redes de transporte de pasajeros y de mercadería del área
metropolitana de Boston y de Nueva Inglaterra. El Aeropuerto es uno de los aeropuertos con la mayor limitación
terrestre del país y está rodeado en tres laterales por el puerto de Boston (consulte las Figuras 1-4 y 1-5 ). 
Crecimiento de la actividad de pasajeros y de aeronaves en el Aeropuerto
Logan 
Al igual que el resto de la industria aeroportuaria estadounidense, el Aeropuerto Logan ha experimentado un
fuerte descenso de la actividad de las aerolíneas y del volumen de pasajeros en los dos últimos años. Los
diferentes estados y regiones dentro de los Estados Unidos han diferido en su respuesta a las restricciones de la
COVID-19, lo que a su vez reflejó la voluntad de los consumidores de reanudar los viajes hacia y desde
determinados mercados. El resultado neto es que la recuperación del transporte aéreo en el Aeropuerto Logan
sigue siendo un trabajo en curso. Aunque en 2020 los pasajeros cayeron a niveles de actividad no vistos desde la

EDR del 2020/2021 del Aeropuerto Internacional Logan de Boston 
Introducción/Resumen ejecutivo 1-10 
década de 1970, en 2021 el Aeropuerto mostró un retorno gradual hacia los niveles de 2019 ( Figura 1-6 ). En el
año 2022, se ha visto una mayor recuperación, pero no en los niveles previos a la pandemia. 
A partir de marzo de 2020, el Aeropuerto Logan experimentó reducciones dramáticas de los niveles de pasajeros
y vuelos asociados con la pandemia de la COVID-19. Los niveles de actividad de pasajeros alcanzaron un total de
aproximadamente 12,6 millones en 2020, una disminución del 70,3 por ciento en comparación con los niveles de
2019. El número total de operaciones de aeronaves en el Aeropuerto Logan se redujo en un 51,6 %, pasando de
427 176 operaciones en 2019 (que fue un máximo histórico desde 2001) a 206 702 operaciones en el 2020. 
En 2021, el Aeropuerto continuó su senda de recuperación y añadió 10,0 millones de pasajeros, y terminó el año
con unos 22,7 millones, recuperando aproximadamente el 53,3 % de los niveles de pasajeros de 2019. Las
operaciones en el 2021 aumentaron a 266 034, lo que representó una recuperación del 62,3 % de los niveles del
2019.

Figura 1-6 Niveles de pasajeros anuales y operaciones de aeronaves en el Aeropuerto Logan (1990-
2021) 
Los niveles de actividad del Aeropuerto Logan están estrechamente
ligados a la economía regional y nacional 
Los niveles de actividad del Aeropuerto Logan son impulsados ampliamente por las economías locales,
regionales y nacionales. Tal como puede verse al observar las tendencias a largo plazo, está claro que
cuando la economía es fuerte, el Aeropuerto Logan crece. Análogamente, las disminuciones más
importantes en los niveles de pasajeros y en el funcionamiento de las aeronaves se observan muy cerca
de perturbaciones nacionales e internacionales importantes. Ejemplos de las disminuciones más
significativas incluyen la huelga de la Organización de Controladores Profesionales de Tráfico Aéreo
(Professional Air Traffic Controllers Organization, PATCO) en 1981, el 11 de septiembre del 2001, la Gran
Recesión en el 2008/2009 y ahora la pandemia de la COVID-19. 
Cuando ha habido un crecimiento significativo, como se observó hasta el 2018 y el 2019, Massport ha
puesto en práctica estrategias para abordar ese crecimiento de manera que permita que el Aeropuerto
Logan evolucione de manera sostenible y ambientalmente responsable. 
El Aeropuerto Logan es el aeropuerto más grande de los seis estados de la región de Nueva Inglaterra,
que tiene una población de aproximadamente 15,1 millones de residentes en el 2021. El Aeropuerto está
ubicado en Massachusetts, que alberga a 7,0 millones de residentes o cerca del 46,6 por ciento de la
población de Nueva Inglaterra hasta el 2021. El Aeropuerto Logan presta servicios a pasajeros de toda
Nueva Inglaterra y la principal zona de influencia está compuesta por los siguientes cinco condados de

Massachusetts: Essex, Middlesex, Norfolk, Plymouth y Suffolk (que incluye la ciudad de Boston). Según las
estadísticas disponibles más recientes, 4,4 millones de personas residen en estos cinco condados. 
Antes de la COVID-19, el área metropolitana de Boston había mantenido en forma constante una menor
tasa de desempleo que la de la Mancomunidad y que la del país. En 2019, el área estadística
metropolitana de Boston tenía una tasa de desempleo del 2,8 por ciento, que era menor que la tasa de la
Mancomunidad (3,1 por ciento) y que la del país /(3,7 por ciento). Incluso durante los años de la recesión
económica de 2008/2009, Boston y la Mancomunidad sufrieron tasas de desempleo por debajo del
promedio nacional. 4 Massachusetts registró recientemente una tasa de desempleo históricamente alta del
16,7 por ciento en abril del 2020, que fue mayor que la tasa de desempleo nacional del 14,4 por ciento el
mismo mes. 5 Después de alcanzar tasas de desempleo récord en el punto álgido de la pandemia en 2020,
la tasa de desempleo de la Mancomunidad continuó bajando de forma constante en los meses restantes
del 2020 y a lo largo del 2021, cayendo al 4,1 % en diciembre del 2021. El Aeropuerto no solo atiende a
una población en crecimiento, sino también a una población con mayores ingresos. El ingreso per capital 
en el 2020 fue de USD 85 724 (dólares estadounidenses actuales) en el área de servicios principal del
Aeropuerto, 11,3 por ciento más alta que en la Mancomunidad y 44,9 por ciento más alta que el
promedio nacional. 6 
El Aeropuerto Logan es un recurso de transporte y económico clave en la región de Nueva Inglaterra, en
el estado y en el área metropolitana de Boston, que alberga una gran variedad de industrias y cuenta con
una población relativamente más rica en comparación con el promedio de los EE. UU. Las industrias con la
mayor cantidad de empleados incluyen la atención médica y la asistencia social, 7 los servicios educativos,
profesionales, científicos y tecnológicos (que incluyen la creciente industria biotecnológica de Boston). 8 En
2019, Boston/Cambridge, la mayor agrupación biofarmacéutica del país, se comprometió a impulsar la
salud digital a través de la creación de una base de datos de registros sanitarios digitales en la que se
espera que la industria crezca hasta generar más de USD 350 000 millones de dólares en valor anual para
el 2025. 9 Incluso durante el apogeo de la pandemia mundial, que provocó una recesión económica en
otros sectores empresariales, la industria biofarmacéutica de la Mancomunidad siguió prosperando,
añadiendo unos 85 000 puestos de trabajo y recaudando más de USD 5800 millones en capital de riesgo. 
Además de respaldar el crecimiento y éxito económico del estado, el Aeropuerto Logan y la industria
aeroportuaria siempre han sido elementos importantes para la economía estatal y regional. La

Departamento de Transporte de Massachusetts (Massachusetts Department of Transportation, MassDOT)
en el 2014 y actualizada más recientemente en 2019, 10 calcula que los aeropuertos de Massport (incluidos
el Aeropuerto Logan, Worcester Regional Airport y Hanscom Field) contribuyen con aproximadamente
USD 23,1 mil millones en producción a la economía de Massachusetts anualmente. De esta producción, el
71 por ciento se debe solo al Aeropuerto Logan. 11 La producción total incluye negocios dentro del
aeropuerto, construcción, visitantes y efectos multiplicadores (consulte la Figura 1-7 ). 12 El Aeropuerto
Logan respalda más de 162 000 puestos de trabajo directos e indirectos, al mismo tiempo que genera
aproximadamente USD 16,3 mil millones por año en producción económica total. 13

EDR del 2020/2021 del Aeropuerto Internacional Logan de Boston 
Introducción/Resumen ejecutivo 1-16 
El Aeropuerto Logan se considera un aeropuerto de origen y destino (O&D) 14 tanto nacional como
internacionalmente, lo que significa que, aproximadamente, el 90 por ciento de los pasajeros del
Aeropuerto Logan inician o finalizan su viaje en el Aeropuerto Logan. Los aeropuertos principales, como el
de Atlanta o Chicago, prestan servicios a muchos más pasajeros anualmente, pero en comparación con
los aeropuertos de O&D, como el Aeropuerto Logan, pasa un porcentaje mayor de pasajeros en tránsito
en los aeropuertos principales a través de los vuelos de conexión. El Aeropuerto Logan se considera un
aeropuerto de origen y destino nacional e internacional, lo que significa que menos del 10 % de los
pasajeros aéreos conectan a través del aeropuerto Logan. 
Estado de las predicciones 
En el ESPR del 2017 , se presentó una predicción actualizada para las operaciones de las aeronaves y la
actividad de los pasajeros del Aeropuerto. La predicción se centró en un horizonte de planeación futura
que incluyó una proyección de 50 millones de pasajeros aéreos anuales y 486 000 operaciones de
aeronaves anuales. Las proyecciones del ESPR de Massport fueron congruentes con la proyección del área
de la terminal de la Administración Federal de Aviación (FAA) en ese momento. Sin embargo, la pandemia
de la COVID-19 ha reducido drásticamente el tráfico de pasajeros aéreos en el 2020 y 2021, y no se
espera volver a los niveles de 2019 a corto plazo. 
Debido a la economía sólida en los meses anteriores al inicio de la pandemia de la COVID-19, los niveles
de actividad de los pasajeros y las operaciones de las aeronaves en el aeropuerto de Logan aumentaron
rápidamente. Ese crecimiento se debió en gran parte a las condiciones económicas positivas en la región
de Boston, el bajo desempleo, una base económica diversa y fuerte, y la inversión continua en bienes
raíces comerciales y residenciales, en ciencias biológicas en particular, en las finanzas, en la atención
médica y en la educación superior. Al igual que en otros aeropuertos de los EE. UU., esta tendencia de
crecimiento se vio alterada en marzo del 2020, al comienzo de la pandemia. 
En consecuencia, las proyecciones del ESPR del 2017 tendrán que actualizarse a medida que se
comprendan mejor los efectos a más largo plazo de la pandemia de la COVID-19. La metodología para las
próximas previsiones del ESPR del 2022 se preparará utilizando técnicas de previsión estándar del sector,
que incluyen los siguientes análisis: 
 Patrones históricos de tráfico aeroportuario y tarifas aéreas. 
 Datos históricos socioeconómicos y demográficos. 
 Estrategias de las aerolíneas y tendencias de la industria. 
 Previsión de datos socioeconómicos y demográficos. 
Esta metodología es similar a la utilizada por la FAA para desarrollar la Previsión del Área de Terminal. 
14 El “tráfico de origen y de destino” se refiere al tráfico de los pasajeros que se origina o que termina en un aeropuerto o en un
mercado en particular. Un mercado de O&D fuerte, como Boston, genera una demanda local de pasajeros significativa, ya que
muchos pasajeros inician y terminan su viaje en ese mercado. El tráfico de O&D es diferente al tráfico de conexión, que es
tráfico de pasajeros que no inician ni terminan en el aeropuerto, sino que solo hacen conexiones en el aeropuerto en ruta hacia
otros destinos.

Introducción/Resumen ejecutivo 1-17 
Las previsiones se elaborarán combinando una metodología microeconómica ascendente (a corto plazo) y
una metodología macroeconómica descendente. La previsión ascendente incluye una revisión de las
tendencias recientes del sector y de las expectativas de los futuros datos de servicios y horarios de las
aerolíneas. Incorporará las aportaciones de las compañías aéreas en relación con la recuperación de la
capacidad a corto plazo de la COVID-19, así como las aportaciones de grupos comerciales del sector
como Airlines For America (A4A), la Asociación Internacional de Transporte Aéreo (International Air
Transport Association, IATA) y el Consejo Internacional de Aeropuertos (Airports Council International,
ACI). Estos grupos industriales proporcionan un contexto importante en la recuperación de los mercados
de entrada, como Boston, en comparación con los mercados nacionales y regionales.

nacionales servirán de base para la previsión descendente a largo plazo. Anteriormente, factores
econométricos como el Proyecto Interior Bruto (Gross Domestic Project, GDP) de los Estados Unidos, el
GDP regional, la renta personal total regional y el costo del combustible sirvieron como variables
independientes representativas en el análisis de regresión. Dado el tamaño del mercado de Boston y su
fuerte economía, estos factores pueden volver a utilizarse en las previsiones de la demanda de aviación
del ESPR del 2022 . 
También es importante señalar que, dada la posición del Aeropuerto Logan en el mercado regional del
noreste, también se tendrán en cuenta las tendencias y la dinámica del mercado en otros aeropuertos
cercanos, como el Aeropuerto Regional de Manchester-Boston (MHT) y el T.F. de Rhode Island T.F. Green
International Airport (PVD). 
Inversiones de Massport en el Aeropuerto Logan 
Massport controla, evalúa e implementa mejoras constantemente en el Aeropuerto Logan, en la
seguridad, en la eficacia operativa y en el acceso desde y hacia el área metropolitana de Boston, mientras
controla atentamente los efectos medioambientales de las operaciones del Aeropuerto Logan. Los
proyectos del área de la terminal recientes y en curso están destinados a brindar una conectividad
posterior a la seguridad sin inconvenientes entre las terminales y mejoras al sistema de proceso de
pasajeros a través de las áreas de verificación de seguridad consolidadas. El acceso al Aeropuerto Logan y
sus alrededores continúa siendo una prioridad. Massport continúa trabajando con la FAA para mejorar la
seguridad en la zona de operaciones a través de una variedad de mejoras en la seguridad del área de las
pistas (runway safety area, RSA) y de simplificaciones en la geometría del campo de aviación 
Como se mencionó anteriormente, los efectos de la pandemia de la COVID-19 han precipitado una gran
serie de cambios en el Aeropuerto Logan. Tanto la disminución de los pasajeros como los ingresos
asociados en el 2020 y 2021 han requerido importantes ajustes en los servicios y en los cronogramas de
los proyectos. Massport se ha centrado en ajustar los servicios para que se ajusten a los cambiantes
niveles de pasajeros y en asegurar que esos cambios se hagan teniendo muy en cuenta la gestión de los
impactos ambientales y operativos. En algunas áreas, se ajustaron los programas para reflejar las
necesidades actuales y los impactos. Massport mantiene su compromiso de aplicar las estrategias de

Aspectos destacados y hallazgos clave del 2020 y 2021 
Esta sección brinda un breve resumen de los hallazgos clave, por capítulo, en el Aeropuerto Logan en el
2020 y 2021. Se ofrece información adicional sobre las actividades del Aeropuerto en los capítulos
subsiguientes. Esta sección también destaca las iniciativas de Massport para una mayor sustentabilidad a
través de proyectos específicos e iniciativas con una hoja de sustentabilidad y resume el programa de
sustentabilidad de Massport. 
La certificación del secretario para el EDR del 2018/2019 , que constituyó el alcance de este EDR del
2020/2021 , reconoció que los niveles de actividad y las operaciones han disminuido debido a la pandemia
de la COVID-19. Dada la anomalía de este calendario de informes, la MEPA ordenó que se presentara un
EDR del 2020 y 2021 combinado para proporcionar una indicación más clara de las tendencias de
crecimiento posteriores a la pandemia, junto con una metodología para la próxima previsión futura. 
A partir de la presentación de este EDR del 2020/2021 , el Aeropuerto Logan sigue recuperándose de la
reducción de la demanda por la pandemia de la COVID-19. Los efectos de la COVID-19 en la industria de
la aviación y el Aeropuerto de Logan siguen evolucionando. Como consecuencia, el ESPR del 2022 
proporcionará una previsión actualizada, reflejando la continua recuperación de la pandemia, así como los
cambios de la industria que están reconfigurando la aviación en los Estados Unidos y a nivel internacional. 
Niveles de actividad 
Hasta el inicio de la pandemia de la COVID-19, el Aeropuerto Logan (y la industria de la aviación en
general) había estado experimentando un fuerte crecimiento, en gran parte por las condiciones
económicas positivas en la región de Boston, el bajo desempleo, una base económica diversa y fuerte, y la
inversión continua en bienes raíces comerciales y residenciales, en ciencias biológicas en particular, en las
finanzas, en la atención médica y en la educación superior. Debido a la pandemia de la COVID-19, los
niveles de pasajeros y las operaciones del 2020 han disminuido drásticamente y los niveles de pasajeros
del 2021 muestran un retorno gradual hacia los niveles del 2019. 
Al igual que el resto de la industria aeroportuaria estadounidense, el Aeropuerto Logan ha experimentado
un fuerte descenso de la actividad de las aerolíneas y del volumen de pasajeros en los dos últimos años.
Los diferentes estados y regiones dentro de los EE. UU. han diferido en su respuesta a las restricciones de
la COVID-19, lo que a su vez reflejó la voluntad de los consumidores de reanudar los viajes hacia y desde
determinados mercados. El resultado neto es que la recuperación del transporte aéreo en el Aeropuerto
Logan es un trabajo en curso. El Aeropuerto Logan se ha recuperado a un ritmo más lento si se compara
con la recuperación general de pasajeros programados en los Estados Unidos, que recuperó el 72,7 % de
sus niveles del 2019 en 2021. 15 Antes de la pandemia, el Aeropuerto Log
