287 one nautical mile (2 km) north of the central business district of West Yellowstone, a town in Gallatin County, Montana, United States.

West Yellowstone was served with Douglas DC-3's and was one of many stops on a route between Los Angeles, California and Great Falls, Montana.

During the summer of 1973, Western was operating four 737 flights a day into the airport with nonstop jet service to Butte, MT; Great Falls; MT, Idaho Falls, ID; and Salt Lake City; as well as flying direct, no change of plane jet service to Las Vegas; Ontario, CA; San Diego; and San Francisco.

The original Frontier Airlines (1950-1986) began serving the airport in 1967 with summer seasonal service operating direct flights to Denver using Convair 580 turboprop aircraft.

SkyWest Airlines took over the service to West Yellowstone beginning with the summer 1986 travel season operating flights to Salt Lake City.

This Delta Connection service to Salt Lake City began with the summer 1987 season and continues today.

Service was initially flown with Embraer EMB 120 Brasilia turboprop aircraft and was upgraded with Bombardier CRJ-200 regional jets in 2015 and to CRJ-900's in 2024.

[1] Choice Aviation, the airport's fixed-base operator (FBO), offers fuel, flight instruction, aircraft/hangar rental, and other services.

One of the largest aircraft ever to use the airport was a USAF KC-135 Stratotanker operated by the Air National Guard with this aerial refueling tanker jet performing several "touch and go" landings and takeoffs on June 8, 2022.

The base also supports visiting jumpers, tankers and other aerial firefighting resources during times of high fire activity.
