The airport sits in Flathead County, about six miles northeast of Kalispell, and is the main commercial gateway to Glacier National Park.

The Flathead Municipal Airport Authority, a public agency created by the county in 1974, owns and runs it. Its ICAO code is KGPI, though many airlines still use the older code KFCA for reservations.
