The airport covers 136 acres at an elevation of 2,467 feet above mean sea level and serves primarily general aviation operations. The facility is included in the National Plan of Integrated Airport Systems and is categorized as a general aviation airport.
The airport features a single asphalt runway designated 7/25, measuring 4,200 feet long by 75 feet wide. The runway is equipped with a PAPI (Precision Approach Path Indicator) on runway 07 and a VASI (Visual Approach Slope Indicator) on runway 25, both oriented to steer aircraft clear of local mountain obstructions. The airport also maintains a large apron area for aircraft tiedown operations.
Facilities at Thompson Falls Airport include a pilot's room and a courtesy car for pilots needing transportation to connect with the local business community. The airport is located 2.5 miles east of town, and when the courtesy car is unavailable, pilots can call the airport manager at 406-546-6384 for transportation to town. Currently, there are no fixed-base operators (FBOs) reporting fuel services at the airport.
For safety, the airport is surrounded by a complete perimeter fence to keep wildlife such as deer, elk, moose, and bighorn sheep off the runway. The airport averages approximately 19 general aviation operations per day, with 12 aircraft based at the facility, all single-engine aircraft. The airport provides essential aviation services to the Thompson Falls area and surrounding Sanders County region.

💡 Connection Tips
Allow extra time for transfers at Thompson Falls Airport, serving this rural Montana community in Sanders County near the Idaho border. The facility coordinates closely with Spokane and Great Falls air traffic control centers for flight planning and routing through mountainous terrain. Local aviation services focus on general aviation support including fuel services, aircraft storage in hangars, basic maintenance capabilities, and recreational flying training for mountain operations. The airport's strategic location serves Sanders County communities, recreational pilots accessing Montana wilderness areas, business aviation supporting local industries, and emergency medical evacuation services for isolated mountain communities.
Ground transportation options include a courtesy car for pilots, local taxi services to Thompson Falls (2.5 miles), rental vehicles through advance arrangement, and coordination with the airport manager at 406-546-6384 when transportation needs arise. The facility operates with a 4,200-foot asphalt runway at 2,467 feet elevation, providing essential connectivity for this remote region surrounded by mountain wilderness and limited ground transportation options. Wildlife management includes perimeter fencing to prevent deer, elk, moose, and bighorn sheep from accessing runway areas, a common challenge for mountain airports in this region. Weather monitoring relies on pilot reports and regional forecasting services, as the facility lacks sophisticated meteorological equipment.
Emergency services coordinate with local fire and rescue departments and regional medical facilities, with serious cases requiring evacuation to larger regional hospitals in Spokane or Missoula. Seasonal weather variations during winter months dramatically affect flight schedules, with snow and ice conditions requiring careful planning, while summer offers optimal flying conditions for both recreational and business aviation. Weather patterns including winter storms, mountain fog, and seasonal temperature variations significantly impact operations, requiring flexible scheduling and careful monitoring of changing conditions in the Northern Rocky Mountains.
