Missoula International Airport

Missoula Montana Airport (KMSO) sits 4 miles northwest of downtown Missoula, Montana, in the Bitterroot Valley of western Montana. The field handles modest commercial service (Alaska, Delta, United, American, Allegiant, Sun Country) and a meaningful flow of business aviation, particularly the University of Montana academic / athletic flow (Grizzlies football game days), the year-round Western Montana leisure tourism (Glacier National Park, Bitterroot Valley fly fishing, the Mission Mountains), and the Missoula corporate community. The two runways at KMSO (12/30 9,503 ft, 11/29 4,617 ft) handle every current business jet without restriction. Two FBOs (Northstar Jet Center and Minuteman Aviation) handle business movements. Field elevation is 3,205 feet, with significant summer density-altitude considerations. The surrounding terrain — KMSO sits in a valley with rising mountains on all sides — adds approach complexity in low visibility. The dominant operational considerations are Montana winter weather (heavy snow, persistent cold, frequent deicing), summer wildfire smoke (Western Montana has experienced severe fire seasons in recent years that can constrain operations), and the orographic effects of the surrounding ranges. Ground time to downtown Missoula is 10 minutes; the University is 10; Glacier National Park via US-93 N is 2.5 hours.
