Bozeman Yellowstone International Airport (IATA: BZN, ICAO: KBZN, FAALID: BZN) (Gallatin Field) is an airport located in Belgrade, Montana, United States, eight miles (13 km; 7 nmi) northwest of Bozeman. Owned by the Gallatin Airport Authority,[1] it has been Montana's busiest airport since 2013.[3]
In 2011, a terminal expansion designed by Prugh & Lenon Architects opened, adding three gates and more retail concessions.[7] The firm designed expansions and renovations made in 1995 and 1997.[8]
The airport had an expansion of service in 2020 and 2021 to a record 31 nonstop destinations as airlines entered the market or added new routes to serve increased leisure demand. Allegiant Air added nonstop service from three cities; Alaska Airlines added two new routes; startup airline Avelo Airlines began service to one destination; and Southwest Airlines, the largest airline without service to any city in Montana, entered Montana for the first time with two destinations from Bozeman, later adding several more.[10] Several of the markets added had never been commercially served from Bozeman before, including Washington, D.C. (Dulles) and Nashville.[citation needed]
In April 2023, Summit Aviation began construction on a new facility to support its services for Gallatin College as well as its own flight training, charter service, and aircraft management services.[11]
In 2024, the airport announced a $180-million dollar infrastructure upgrade and expansion.[12] This expansion, the largest ever in Montana history, will include the addition of three new baggage carousels, a second security checkpoint, and the capability to add on three more gates. The expansion is expected to be completed within the next 4.5 years.[12]
