The table above depicts the formulae used for the definition of airport categories based on statutory provisions cited within the table, including Hub Type described in 2. For example, calendar year 2014 data are used for fiscal year 2016 since the fiscal year began 9 months after the end of that calendar year. Hub categories for Primary Airports are defined as a percentage of total passenger boardings within the United States in the most current calendar year ending before the start of the current fiscal year.

Primary Airports are Commercial Service Airports that have more than 10,000 passenger boardings each year.

Nonprimary Commercial Service Airports are Commercial Service Airports that have at least 2,500 and no more than 10,000 passenger boardings each year.

Passenger boardings at airports that receive scheduled passenger service are also referred to as Enplanements. 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 refueling or aircraft maintenance rather than passenger activity.

Passenger boardings refer to revenue passenger boardings on an aircraft in service in air commerce whether or not in scheduled service.

Commercial Service Airports are publicly owned airports that have at least 2,500 passenger boardings each calendar year and receive scheduled passenger service.

Five roles are utilized: National, Regional, Local, Basic, and Unclassified. Nonprimary airports are identified with a role in the national airport system based on their activity. Included in this category are the nonprimary commercial service, reliever, and general aviation airports.
