Airport guide

Bert Mooney Airport sits at 5,545 feet MSL, which is the most operationally relevant fact about it. High density altitude affects aircraft performance year-round and is a planning consideration for your operator, particularly in summer. The airport is otherwise uncongested and slot-free, with no commercial airline competition for ramp space.

Silverhawk Aviation operates FBO services at KBTM, handling fuel, ground support, and passenger amenities. The facility is modest by major-market standards, but Butte is a small city and the airport serves it well for general and charter operations. Winters are cold and snowy, and ground delays from snow removal are common from November through March. If you are arriving for skiing at Discovery Ski Area or using Butte as a staging point for western Montana, build weather buffer into your itinerary.

Getting there

Downtown Butte is about 3 miles northeast of the airport, a 7 to 10 minute drive. Rental cars are available on-site. There is no scheduled car service or shuttle at the airport, so arrange a rental or coordinate pickup in advance. If you are heading to Bozeman, that is roughly 65 miles east on I-90, about an hour by car. Missoula is approximately 120 miles northwest, around 1 hour 45 minutes.
