Frequently asked questions
What is the main runway length at KBZN?
Bozeman Yellowstone International's primary runway, 12/30, measures 8,994 feet long and 150 feet wide with an asphalt surface. This is the longest of four runways at the airport and the one most used by business and turbine traffic. A secondary paved runway, 11/29, spans 5,050 feet by 75 feet. Two shorter runways, a 2,802-foot turf strip and a 2,650-foot asphalt runway, serve lighter general aviation traffic. KBZN's pavement supports operations well beyond typical piston and light turboprop weights.
Does KBZN have customs available onsite?
Yes, Bozeman Yellowstone International has CBP inspection services available onsite, along with a USDA compliance agreement. This allows arriving international flights to clear customs directly at the airport rather than diverting to another facility. The combination of CBP and USDA coverage is relevant for operators bringing in aircraft, cargo, or passengers subject to agricultural inspection. Crews should confirm current hours and procedures with the airport ahead of an international arrival, since onsite availability does not guarantee round-the-clock coverage.
What happens at KBZN when the control tower is closed?
When the tower is closed at Bozeman Yellowstone International, pilots must activate lighting themselves via CTAF, including the MALSR system for runways 12 and 30, HIRL for runway 12/30, and MIRL for runway 11/29. The PAPI on runways 12 and 30 operates continuously regardless of tower status. Clearance delivery during tower closure routes through Big Sky Approach; if approach is also closed, pilots should contact Salt Lake ARTCC. Snow removal equipment also communicates on CTAF, which is worth monitoring during winter operations at KBZN.
Is there a weight restriction on any runway at KBZN?
Yes, at Bozeman Yellowstone International there is a runway location between runway 12/30 and taxiway A that is available only to aircraft greater than 12,500 pounds, and only during day / VFR conditions. This restriction is tied to a specific runway identification point rather than the airport's main runways generally. Operators of lighter aircraft should plan routing accordingly and confirm current taxiway and runway configuration with air traffic control before taxi. This detail matters most for turboprop and jet operators using that specific area of the field.
Why does business aviation traffic at KBZN vary so much by month?
Business aviation traffic at Bozeman Yellowstone International is concentrated in specific months rather than spread evenly across the year, according to FAA TFMSC data for 2025. Traffic volumes are notably higher in the winter months of January, February, and December, along with a summer peak in July, compared to the lower counts seen in April, May, and November. Dispatchers planning trips to KBZN during these higher-volume windows should anticipate more congestion in ramp space and scheduling. This pattern reflects seasonal demand rather than a fixed operational limitation at the airport.
