The decision as to what degree of subsidized service a community requires is made based on identifying a specific
hub for the community and from there determining the number of trips, seats, and type of aircraft that are necessary to serve that hub.
These increases occurred despite numerous Congressional measures to contain program spending.
The
George W. Bush Administration sought to reduce the cost of the program to $50 million by stricter eligibility criteria and requiring the local governments of the areas served to contribute to the cost.

has reported in 2018 that since the early 2000s federal subsidies for the EAS have nearly tripled to almost $300 million per year.
By May 2023, the subsidies amounted to $394.2 million per year.
Community eligibility criteria

Pursuant to the Department of Transportation and Related Agencies Appropriations Act of 2000, no community within the 48 contiguous states may receive a subsidy greater than $200 per passenger unless the community is more than from the nearest large or medium hub airport. Pursuant to the FAA Modernization and Reform Act of 2012, to be eligible for the program, a community in the contiguous 48 states must either maintain an average of 10 or more enplanements per service day or be located more than from the nearest large or medium hub airport. The criteria for 10 or more enplanements can be waived by the Secretary of Transportation, on an annual basis, if a community can demonstrate that it is due to a temporary decline.
The Department of Transportation, pursuant to the Consolidated and Further Appropriations Act of 2015, is required to negotiate a local cost share with communities located less than from a small hub airport.

Critics question the economic and environmental efficiency of the service.

The program is politically popular in the cities receiving the subsidized flights, many of which use an airport with scheduled service as a selling point to attract industry to their regions. Several subsidized airports are within an hour's drive from an unsubsidized airport.

Alternate Essential Air Service
The Alternate Essential Air Service program grants funds directly to the municipality or airport authority instead of the air carrier. This allows the community to recruit air service that would not otherwise meet EAS guidelines, such as more frequent service with smaller aircraft, less-than-daily service, flights to differing destinations at different times of the year or week, on-demand

Title 14 of the Code of Federal Regulations, Part 380. The first airport to enter this program was

Community Flexibility Pilot Program
Under the Community Flexibility Pilot Program, established in 2003, up to ten communities can receive a grant equal to two years' worth of subsidy in exchange for forgoing their EAS service for ten years. These grants must be used to fund projects that will improve the airport for general aviation. As of 2020, only one community has ever taken advantage of the program:
