Frequently asked questions
Is customs available at KGPI?
Glacier Park International offers onsite CBP inspection services, with a USDA compliance agreement also in place. This allows arriving international flights to clear directly at the airport rather than diverting to another port of entry. The airport is towered and operates on an ALL / ALL / ALL attendance schedule, meaning services are available year-round without seasonal restrictions. Crews planning international arrivals into KGPI should still coordinate directly with CBP given the compliance agreement structure covering agricultural inspection.
What runway options does KGPI have for business jets?
Glacier Park International provides two paved asphalt runways. Runway 02/20 is the primary surface at 9,007 feet long and 150 feet wide, suitable for most business jet categories. Runway 12/30 is considerably shorter at 3,510 feet long and 75 feet wide. Operators at KGPI should plan around the longer runway for larger aircraft, particularly given the field elevation of 2,977 feet.
Does KGPI see seasonal traffic swings?
Yes, business aviation traffic at Glacier Park International concentrates heavily in the summer months. FAA TFMSC data for 2025 shows July as the peak month with 1,502 business aviation operations, followed by August at 1,357. Winter months run much lower, with February and April both recording 513 operations. Dispatchers scheduling trips into KGPI during June through August should anticipate a busier operating environment than the rest of the year.
What cold weather procedures apply at KGPI?
Glacier Park International is designated a cold temperature airport, requiring altitude corrections at or below -14C. This designation affects approach procedures where published minimum altitudes may not provide adequate obstacle clearance in extreme cold. Crews should apply cold temperature corrections to published altitudes when temperatures reach or fall below this threshold. The airport's Montana location and elevation of 2,977 feet make winter operations planning a regular consideration for flights into KGPI.
Are there nearby airspace conflicts to watch for near KGPI?
Yes, Glacier Park International lies near several points of VFR traffic and parachute activity requiring caution. Skydiving operations occur 6 nautical miles northwest of the field, up to 13,000 feet, from sunrise to sunset between June and September, monitored by Salt Lake ARTCC. Additionally, VFR traffic operates at Kalispell City Airport 8 nautical miles south and Whitefish Airport 6 nautical miles northwest of KGPI. Crews operating in the vicinity should maintain awareness of these nearby non-towered fields and seasonal parachute activity.
