Essential Air Service: Frequently Asked Questions

Introduction
The 112th Congress continues to work on reauthorizing the Federal Aviation Administration
(FAA). Essential Air Service (EAS) is one of the major issues being debated in the process. A
pending House reauthorization bill (H.R. 658) and the reauthorization bill recently approved by
the Senate (S. 223) include different provisions affecting the EAS program, and the issue is also
addressed in H.R. 408, the Spending Reduction Act of 2011.
This report provides an overview of the EAS program and the legislative issues.1
What is Essential Air Service?
The Airline Deregulation Act of 1978 (P.L. 95-504) gave airlines almost total freedom to
determine which domestic markets to serve and what airfares to charge. This raised the concern
that communities with relatively low passenger levels would lose service as carriers shifted their
operations to serve larger and often more-profitable markets.
To address this concern, Congress added section 419 to the Federal Aviation Act,2 which
established the Essential Air Service (EAS) program to ensure that smaller communities would
retain a link to the national air transportation system. The purpose of the EAS program is to
provide a continuation of service to those small communities that were served by certified air
carriers before deregulation, with subsidies if necessary.
The EAS program is now administered by the Department of Transportation (DOT), which
determines the minimum level of service required at each eligible community by specifying
• a hub through which the community is linked to the national network,
• a minimum number of round trips and available seats that must be provided to
that hub,
• certain characteristics of the aircraft to be used, and
• the maximum permissible number of intermediate stops to the hub.
Where necessary, DOT provides federal subsidies to a carrier to ensure that the specified level of
service is provided.

2 Effective June 1994, the Federal Aviation Act was recodified as subtitles II, III, and V-X of 49 U.S.C.,
“Transportation.” The former section 419 of the Federal Aviation Act is now 49 U.S.C 41731-41742.

Essential Air Service: Frequently Asked Questions

How Is EAS Funded?
The EAS program is funded through annual transfers of FAA overflight fees, supplemented by
annual appropriations of varying size.
In FY2010, the total EAS authorization was $200 million. This amount includes $50 million in
annual mandatory funding from FAA overflight fees, along with a discretionary appropriation of
$150 million.
What Are the Eligibility Requirements?
According to the Airline Deregulation Act of 1978 (P.L. 95-504), communities receiving
scheduled air service from a certified carrier on October 24, 1978, are eligible for EAS benefits.
At that time, there were 746 eligible communities, including approximately 200 in Alaska.
Over the years, Congress and DOT have worked to streamline the program and make it more
efficient, mostly by eliminating subsidy support from communities within a reasonable driving
distance from a major hub airport. Communities are excluded from eligibility for subsidies if
• they are located fewer than 70 miles from the nearest large or medium hub
airport; or
• they require a rate of subsidy per passenger in excess of $200, unless the
community is more than 210 miles from the nearest hub airport.
These limitations apply only to the contiguous 48 states. However, these eligibility requirements
may change depending on the final text of which legislation, if any, is adopted by Congress.
How Many Communities Are Receiving
EAS Subsidies?

DOT currently subsidizes air service to serve approximately 150 rural communities across the
country that otherwise would not receive any scheduled air service. As of May 1, 2010, DOT was
subsidizing service at 109 communities in the contiguous 48 states, Hawaii, and Puerto Rico, and
44 communities in Alaska. Appendix A and Appendix B provide lists of the subsidized EAS
communities and their annual subsidy rates (as of May 1, 2010). In general, DOT subsidizes two
to four round trips with small aircraft a day from an EAS community to a major hub airport.
How Does DOT Select EAS Carriers?
DOT issues a request for proposals (RPF) to all scheduled carriers and institutes a carrier
selection proceeding using a bid system. However, this is not a low-bid system because DOT is
required by the governing statutes to meet the following four criteria when selecting air carriers to
serve EAS communities: (1) service reliability, (2) contractual and marketing arrangements with a

larger carrier at the hub, (3) interline arrangements with a larger carrier at the hub, and (4)
community views.
These RFPs from DOT advise air carriers that their proposals for subsidy should be submitted on
a sealed bid, “best and final” basis, and set forth the level of service (frequency, aircraft size, and
hubs) that would be appropriate for the community given its location and traffic history. Once the
carrier proposals are received, DOT formally solicits the views of the communities as to which
carrier and option they prefer.
After receiving the communities’ input, DOT issues a decision designating the selected air carrier
and specifying the specific service pattern (routing, frequency, and type of aircraft), annual
subsidy rate, and effective period of the rate. DOT generally establishes a two-year EAS service
contract, which allows for the competitive bidding process to curb subsidy costs and gives
communities and DOT flexibility to switch carriers if appropriate.
What Are the Current Legislative Issues?
The 112th Congress continues to work on legislation reauthorizing the FAA. A pending House bill
and the recently approved Senate bill include different provisions with regard to EAS.
An FAA reauthorization bill (H.R. 658) would phase out the program over three years, ending
EAS in the contiguous states on September 30, 2013. Only Alaska and Hawaii would be eligible
for EAS subsidies afterwards. The current cost of EAS in Alaska is less than $13 million
annually. As of May 1, 2010, EAS flights in Hawaii were subsidy-free. H.R. 658 would reduce
the mandatory annual appropriation to the amount necessary to provide EAS in those two states.
H.R. 408 would prohibit the spending of any federal money for EAS.
The bill passed by the Senate on February 17, 2011 (S. 223), would extend the program but add
more restrictions. Specifically, it would limit EAS subsidies to airports that are 90 miles or more
from the nearest medium or large hub, an increase from the current limit of 70 miles. S. 223
would also limit EAS subsidies to locations that have 10 or more enplanements per day, except in
Alaska. However, the FAA administrator would be able to waive both the distance requirement
and the minimum enplanements requirement. An amendment to the bill offered by Senator
McCain (S.Amdt. 4) that proposed to repeal the EAS program altogether was tabled and not
included in the Senate-passed version of S. 223.
The FAA reauthorization language would eventually need to be incorporated into a House bill,
because the reauthorization includes an extension of excise taxes and is therefore a revenue
measure. Under Article I, Section 7 of the U.S. Constitution, all bills for raising revenue must
originate in the House of Representatives.
