History
Originally named Gallatin Field after Gallatin County, it first opened in 1941. Its first official passenger landed in 1942.
A number of improvements were made in the late 1960s to accommodate jet service, including extending the main runway to 9,000 feet.
In 2011, the Gallatin Airport Authority Airport Board changed the airport's name to Bozeman Yellowstone International Airport at Gallatin Field, to associate it with Yellowstone National Park. That same year a terminal expansion designed by Prugh & Lenon Architects opened, adding three gates and more retail concessions.
International flights have been allowed since 2012, after a U.S. Customs and Border Protection facility opened on July 1. The project was funded in cooperation with Signature Flight Support and the Yellowstone Club. In 2013, BZN surpassed Billings Logan as the busiest airport in Montana for passenger service with 879,221 passengers from June 2012 to May 2013.
The airport had an expansion of service in 2020 and 2025 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. Several of the markets added had never been commercially served from Bozeman before, including Washington, D.C. (Dulles) and Nashville.
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.
In 2024, the airport announced a $180-million dollar infrastructure upgrade and expansion. 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.
