Airports With Commercial Service: How Many Are There?

Commercial service airports are publicly owned airports that have at least 2,500 passenger boardings each calendar year. These airports receive scheduled passenger service. Airports with more than 10,000 passenger boardings each year are considered primary airports. The FAA further classifies primary airports into four hub types: large, medium, small, and non-primary. Non-primary commercial service airports have between 2,500 and 10,000 passenger boardings annually. Reliever airports are designated by the FAA to relieve congestion at commercial service airports and improve general aviation access.

Commercial Service Airports are publicly owned airports with at least 2,500 passenger boardings each year

The FAA designates four types of hub for Primary Commercial Service Airports: Large, Medium, Small, and Non-Hub. Large hubs account for at least 1% of total US passenger enplanements (generally 18,500,000 total passengers and above). Medium hubs account for between 0.25% and 1% of total US passenger enplanements (generally 3,500,000-18,500,000 total passengers). Small hubs account for between 0.05% and 0.25% of total US passenger enplanements (generally 500,000-3,500,000 total passengers).

Reliever Airports are airports designated by the FAA to relieve congestion at Commercial Service Airports. They may be publicly or privately owned. General Aviation Airports are public-use airports that do not have scheduled service or have fewer than 2,500 annual passenger boardings. Approximately 88% of airports included in the NPIAS are general aviation airports.

Primary Airports are Commercial Service Airports with more than 10,000 passenger boardings each year

Commercial Service Airports are publicly owned airports that have at least 2,500 passenger boardings each calendar year and receive scheduled passenger service. Airports with more than 10,000 passenger boardings each year are known as Primary Airports. These are further classified by the FAA as one of four "hub" types:

• Large hub: accounts for at least 1% of total U.S. passenger enplanements (generally 18,500,000 total passengers and above)
• Medium hub: accounts for between 0.25% and 1% of total U.S. passenger enplanements (generally 3,500,000-18,500,000 total passengers)
• Small hub: accounts for between 0.05% and 0.25% of total U.S. passenger enplanements (generally 500,000-3,500,000 total passengers)

Reliever Airports are airports designated by the FAA to relieve congestion at Commercial Service Airports and to provide improved general aviation access to the overall community. These may be publicly or privately owned. General Aviation Airports are public-use airports that do not have scheduled service or have less than 2,500 annual passenger boardings.

Reliever Airports are designated to relieve congestion at Commercial Service Airports

Commercial Service Airports are publicly owned airports that have at least 2,500 passenger boardings each calendar year and receive scheduled passenger service. These airports are further categorised into primary and non-primary airports. Primary Commercial Service Airports have more than 10,000 passenger boardings each year, whereas Non-Primary Commercial Service Airports have between 2,500 and 10,000 passenger boardings annually.

Primary Commercial Service Airports are further classified into four "hub" types by the FAA: Large, Medium, Small, and Non-Hub. Large hubs account for at least 1% of total US passenger enplanements, generally 18,500,000 passengers and above. Medium hubs account for between 0.25% and 1% of total US passenger enplanements, generally ranging from 3,500,000 to 18,500,000 passengers. Small hubs account for between 0.05% and 0.25% of total US passenger enplanements, typically serving between 500,000 and 3,500,000 passengers.

Reliever Airports are designated by the FAA to alleviate congestion at Commercial Service Airports and enhance general aviation access for the community. These airports may be publicly or privately owned. They are defined as having less than 2,500 annual passenger boardings.

General Aviation Airports are public-use airports with less than 2,500 annual passenger boardings

Commercial Service Airports are publicly owned airports that have at least 2,500 passenger boardings each calendar year and receive scheduled passenger service. Passenger boardings refer to revenue passenger boardings on an aircraft in service in air commerce, whether or not in scheduled service. The definition also includes passengers who continue on an aircraft in international flight that stops at an airport in any of the 50 states for a non-traffic purpose, such as refuelling or aircraft maintenance rather than passenger activity.

Passenger boardings at airports that receive scheduled passenger service are also referred to as Enplanements. Non-primary Commercial Service Airports are Commercial Service Airports that have at least 2,500 and no more than 10,000 passenger boardings each year. Primary Airports are Commercial Service Airports that have more than 10,000 passenger boardings each year.

General Aviation Airports are public-use airports that do not have scheduled service or have less than 2,500 annual passenger boardings. Approximately 88% of airports included in the NPIAS are general aviation airports. The FAA completed two top-down reviews of the existing network of general aviation facilities included in the NPIAS. The results of these efforts are contained in two reports ('General Aviation Airports: A National Asset') and have been fully incorporated into the biennial NPIAS.

Certificated airports are airports serving passenger-carrying operations of an air carrier certificated under Part 121 and Part 380

Commercial Service Airports are publicly owned airports that have at least 2,500 passenger boardings each calendar year and receive scheduled passenger service. Airports with more than 10,000 passenger boardings each year are considered Primary Commercial Service Airports. The Federal Aviation Administration (FAA) designates four types of hubs for these primary airports: Large, Medium, Small, and Non-primary. Large hubs account for at least 1% of total US passenger enplanements, generally 18,500,000 total passengers and above. Medium hubs account for between 0.25% and 1% of total US passenger enplanements, generally ranging from 3,500,000 to 18,500,000 total passengers. Small hubs account for between 0.05% and 0.25% of total US passenger enplanements, generally ranging from 500,000 to 3,500,000 total passengers. Non-primary Commercial Service Airports have between 2,500 and 10,000 passenger boardings annually.

Reliever Airports are designated by the FAA to reduce congestion at Commercial Service Airports and improve general aviation access for the community. These can be publicly or privately owned. General Aviation Airports are public-use airports that do not have scheduled service or have fewer than 2,500 annual passenger boardings. Approximately 88% of airports in the NPIAS are general aviation airports.
