Yellowstone Airport – located two miles north of West Yellowstone, MT, on Highway 191 – is owned and operated by the Montana Department of Transportation Aeronautics Division.

Western Airlines began the first service to West Yellowstone in the late 1930’s. Service was seasonal in nature and was not operated during the winter months. 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. Western’s service was suspended through the 1950’s and returned in the mid-1960s, again on a seasonal basis but now using Lockheed L-188 Electra propjets. In 1965, Western claimed in a print advertisement that it was the only air carrier serving the airport which had been rebuilt and expanded into “a brand new, jet-age airport – right at Yellowstone Park”.
