Cut Bank International Airport — Cut Bank, United States

Windswept and often bitterly cold, Cut Bank sits near Montana's Rocky Mountain Front within easy reach of Glacier National Park, and its airport, coded CTB, once trained military pilots during the Second World War as part of a larger Army Air Forces network. Scheduled airline service has long since disappeared, leaving general aviation, agricultural flying, and occasional charter traffic as its main activity today. The town itself has earned a reputation for extreme winter weather, and the airfield's exposed high-plains location contributes to that notoriety. Its long runway, a legacy of wartime construction, remains oversized for current traffic levels.
