2025–2026 Update: The FAA Reauthorization Act of 2024 (P.L. 118-63) increased base AIP authorization to $4.0 billion annually (P.L. 118-63, Sec. 182) for FY2025–2028, with modifications to hub minimum guarantees and other set-asides. Including supplemental BIL/IIJA funding, total AIP-equivalent funding reaches approximately $4.0 billion annually. However, the IIJA/BIL Airport Infrastructure Grant and Airport Terminal Program expire after FY2026 (FY2026 ATP applications due January 15, 2026). Small/non-hub airports received 68% of AIP grants in FY2024 (FAA FY2024 AIP data), with the SCASD program providing grants of up to $1.6 million per community.
A. Introduction
Maintaining scheduled air service to small communities has been a federal policy priority since airline deregulation. As of October 2024, the Essential Air Service program serves 177 communities (DOT data). The Airline Deregulation Act of 1978 eliminated route restrictions and price controls, reshaping commercial aviation route structures. However, deregulation also left small communities vulnerable to service losses as carriers consolidated around profitable routes. To address this concern, the federal government established two primary programs designed to sustain air service and support rural economic development and connectivity.
The Essential Air Service (EAS) program was created concurrently with deregulation in 1978, guaranteeing minimum levels of scheduled air service to eligible communities that had been served by certificated carriers before deregulation. Two decades later, recognizing that EAS alone could not address all air service challenges facing small communities, Congress created the Small Community Air Service Development Program (SCASD) in 2000. This program provides grants for revenue guarantees, marketing, and studies (49 U.S.C. § 41743) to communities to address air service gaps and airfare issues.
Together, EAS and SCASD represent the federal government's congressionally authorized mechanisms (49 U.S.C. §§ 41731–41742, 41743) for sustaining air connectivity to small and rural communities, supporting their economic development, and ensuring that geographic location does not preclude access to the national air transportation network.
B. Essential Air Service (EAS)
B.1 Program Overview
The Essential Air Service program guarantees a minimum level of scheduled air service to communities that were served by certificated carriers before deregulation took effect in 1978. The program is administered by the U.S. Department of Transportation's Office of Aviation Analysis. As of October 2024, the program provided $591.7 million (DOT October 2024 EAS report) in federal subsidies to maintain service to 177 eligible communities across the United States.
B.2 Service Standards
DOT EAS standards require a minimum of two round trips per day using aircraft with 30 to 50 seats, or alternatively, additional frequencies using smaller aircraft with 9 or fewer seats. Service must connect eligible communities to a large or medium hub airport, ensuring air transportation connections for residents and cargo.
B.3 Eligible Communities
As of Fall 2024, 177 communities participate in the EAS program: 65 communities in Alaska and 112 in the contiguous United States, Hawaii, and Puerto Rico. To be eligible, communities must have been served by a certificated carrier before deregulation in 1978 and must meet specific distance and access criteria that determine their need for federal support.
B.4 Carrier Selection and Subsidies
DOT selects carriers through a competitive process, with contracts most commonly spanning two years (DOT EAS contract data, 2024). Subsidies range from $142 to $1,247 per passenger in FY2024 (DOT EAS rates).
B.5 Alternate EAS (AEAS) Program
The Alternate Essential Air Service program offers a different approach by providing grants to municipalities and airport authorities rather than to carriers. This grants-based model allows communities to fund on-demand service or aircraft purchases (DOT AEAS guidelines), enabling design of air service solutions using smaller aircraft, on-demand service, or even aircraft purchase programs. This applicant-designed approach allows communities to tailor solutions to their specific air service needs.
B.6 Challenges
The EAS program faces several challenges. According to the Government Accountability Office, EAS costs increased 33% between 2018 and 2023 in constant 2023 dollars (GAO-23-105838), raising congressional scrutiny. Additional challenges include taxpayer concerns as noted in congressional hearings (House T&I Committee, 2024) about program costs, and debate about whether certain communities near major metropolitan hubs should continue receiving EAS support.
C. Small Community Air Service Development Program (SCASD)
C.1 Program Overview
The Small Community Air Service Development Program is a federal grant program created in 2000 to help small communities address air service and airfare challenges. Administered by the U.S. Department of Transportation, SCASD provides grants for revenue guarantees, marketing, and studies (49 U.S.C. § 41743), unlike EAS, making it accessible to a broader range of communities and allowing diverse strategies for addressing air service needs.
C.2 Eligible Activities
SCASD grants support a range of activities designed to develop or maintain air service, including revenue guarantees to airlines, financial assistance for marketing programs, start-up cost support for new air service, air service studies that identify gaps and opportunities, and ground access improvements that enhance the utility of airport facilities.
C.3 Grant Details
The program distributes up to 40 grants annually, with no more than 4 per state. Individual grants range from $20,000 to approximately $1.6 million. In 2023, the program awarded 19 grants totaling $16.9 million to communities in multiple states, limited to 40 grants annually with no more than 4 per state (49 U.S.C. § 41743).
C.4 Eligibility
SCASD is open to small hub, non-hub, and non-primary airports. A key distinction from EAS is that eligible communities are those NOT currently receiving Essential Air Service or Alternate EAS subsidies. This design ensures that SCASD complements rather than duplicates EAS support.
