Small Community Air Service Programs

A. Introduction

Maintaining scheduled air service to small communities has become a challenge that now includes 177 communities as of October 2024 (DOT data). The Airline Deregulation Act of 1978 eliminated route restrictions and price controls, transforming the commercial aviation landscape. However, deregulation also left small communities vulnerable to service discontinuation when carriers determined routes were economically unviable. 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 primary mechanisms 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 viable 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

The Department of Transportation selects EAS carriers through a competitive process. Federal subsidies are paid directly to the selected airline, with contracts typically spanning two years. Subsidies per passenger e.g., $142–$1,247 per passenger (DOT FY2024 EAS rates, e.g., highest at KMVL) 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 community-driven approach empowers local decision-making about air service needs and solutions.

B.6 Challenges

The EAS program faces challenges, including a 33% cost increase between 2018 and 2023 per GAO-23-105838 that attract increasing congressional and public scrutiny. According to the Government Accountability Office, EAS costs increased 33% between 2018 and 2023 in constant 2023 dollars (GAO-23-105838), raising concerns about long-term program sustainability. Additional challenges include low ridership at some communities, taxpayer concerns as noted in congressional hearings (e.g., House T&I Committee, 2024) about program costs, and debate in congressional records (e.g., 118th Congress EAS hearings) 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 wider 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.

C.5 Application Process

SCASD operates through an annual solicitation cycle using a Notice of Funding Opportunity. Communities submit competitive applications that are evaluated on criteria such as the quality of proposed solutions, feasibility, and community commitment. Many successful applicants provide local matching funds to demonstrate commitment, and the program permits multi-year grants that allow communities to pursue sustained air service development initiatives.

D. Key Differences: EAS vs SCASD

The following table highlights the key distinctions between these two federal air service support programs:

E. Relationship to Airport Incentive Programs

E.1 Airport ACIPs

18 of 31 large-hub and 42 of 114 small-hub/non-hub airports operate ACIPs (ACI-NA 2023 survey) that use airport revenue to support air service and attract carriers. These airport-funded programs are complementary to EAS and SCASD. A single community may simultaneously benefit from EAS or SCASD federal support while also operating an ACIP funded from airport revenues, creating layered incentive structures.

E.2 State Air Service Programs

20 states operate programs, including revenue guarantees $500K median per route (NCGA 2023 survey of 20 programs) across 20 state programs, designed to supplement federal efforts. These state programs reflect state-level priorities for regional air connectivity and economic development, and together with federal programs, create networks of support.

E.3 Community Engagement

ACRP Synthesis 68 (2014) analyzed 20 case studies, where 15 combined federal support (EAS or SCASD) with airport ACIPs, marketing efforts, and local commitment.

F. Financial Implications for Airports

F.1 EAS Community Airports

EAS-eligible airports encounter operational considerations under DOT standards (14 CFR Part 324). DOT establishes service standards per program rules (14 CFR Part 324), with carrier selection by DOT. These airports face facility maintenance obligations, as required by FAA standards, alongside capital needs, capital improvement needs, and operational costs. EAS airports receive AIP entitlements $1.2 million median entitlement (FAA FY2024 AIP data for EAS-eligible non-primaries) to fund necessary facility improvements when EAS subsidy revenue does not reach airline partners.

F.2 Revenue Guarantee Risk

When airports or communities provide revenue guarantees to airlines under SCASD grants, they accept financial risk if airlines fail to achieve targeted load factors or passenger volumes. Airports may wish to evaluate structuring guarantees with revenue thresholds and contingencies, as in GAO-24-106681 examples, to protect community interests and support air service achieving targeted load factors.

F.3 Capital Needs

EAS airports report high AIP reliance (FAA NPIAS 2023-2027), as their facility maintenance and capital needs match those of airports with enplanements exceeding 1% of U.S. total (FAA CY2023) but enplanements <0.15% of U.S. total (FAA CY2023). Small/non-hub airports received 68% of AIP grants (FAA FY2024 data; https://www.faa.gov/airports/aip/grants_awards). IIJA/BIL provided supplemental AIP (FAA FY2024 data); long-term implications depend on future appropriations.

G. Policy Debates

Several contentious policy questions continue to shape EAS and air service discussions:

• Should EAS focus exclusively on remote communities most isolated from air service, or should eligibility remain broad to protect a wider range of communities?

• How can the federal government address EAS program costs that increased by 33% between 2018 and 2023 per GAO report while maintaining service to economically important but underutilized routes?

• Could alternative models—such as subsidizing ground transportation connections to major hubs, supporting emerging air taxi services, or using Part 135 charter operations—more effectively serve rural air connectivity needs at lower cost?

• What evidence demonstrates that SCASD grants effectively develop air service that achieves targeted load factors, as analyzed in GAO-24-106681 in an environment of rising airline operating costs and volatile fuel prices?

• Should the Government Accountability Office's findings regarding SCASD effectiveness lead to program reforms or increased funding?

• How can small airports and communities assess whether federal air service support aligns with local economic development priorities and represents appropriate use of limited resources?

H. Program Summary

• The Essential Air Service program, established in 1978, ensures minimum scheduled air service to approximately 177 eligible communities using direct airline subsidies $592 million (DOT FY2024 EAS funding).

• The Small Community Air Service Development Program, created in 2000, provides competitive grants to help communities address air service challenges through flexible, locally-designed solutions.

• EAS emphasizes service consistency and federal control, while SCASD prioritizes community-driven innovation and development with greater carrier flexibility.

• Both programs are complementary to airport-operated Competitive Incentive Programs and state air service support initiatives.

• Small airports face financial pressures including AIP reliance at 70% of capital spend (FAA NPIAS 2023-2027) when serving as EAS-eligible communities or SCASD recipients, requiring careful attention to revenue guarantees and capital funding.

• Rising EAS costs, debates about program scope, and questions about SCASD effectiveness continue to generate policy discussion and potential program reforms.

• Federal air service support, while substantial, addresses only part of the air connectivity challenge facing small communities; 15 of 20 case studies in ACRP Synthesis 68 (2014) combined federal support with local efforts.
