Busiest U.S. airports by total passenger boardings
The FAA uses passenger boarding for a full calendar year to determine Airport Improvement Program entitlements.The term hub is used by the FAA to identify very busy commercial service airports. Large hubs are the airports that each account for at least one percent of total U.S. passenger enplanements. Medium hubs are defined as airports that each account for between 0.25 percent and one percent of the total passenger enplanements.
The 30 large hubs move 70% of the passengers with a traffic increasing by 2.5% from 2016 to 2017, while the 31 medium hubs grew by 5.2% and sixteen airports lost airline services between 2014 and 2018, from 445 to 429.
Mainline carriers are up-gauging their fleet while scope clauses regional aircraft operations and turboprops and 50-seat regional jets are abandoned: aircraft with 50 seats or fewer represented 30% of domestic departures and 12% of seats offered in 2014, falling to 19% in 2018 and 7% of seats.
Accounting for 18% of passenger traffic, medium hubs stimulate point-to-point services like for Southwest Airlines, operating at 29, carrying most mainline passengers at 24 and more than half at 10.
