KBIL’s 10,518 ft runway and KWYS at 6,649 ft frame Montana flying: long pavement, high fields, mountain weather.
The brief
Montana rewards planning more than speed. The state has 126 public-use airports, but only 6 are towered. That leaves 120 non-towered fields where position reports, wind checks and self-briefing matter. The long runways at KBIL (BILLINGS LOGAN INTL), KGTF (GREAT FALLS INTL) and KMSO (MISSOULA MONTANA) give IFR travelers solid anchors across the state. Terrain changes the mission quickly. KBZN (BOZEMAN YELLOWSTONE INTL) sits at 4,473 ft. KBTM (BERT MOONEY) is 5,551 ft. KWYS (YELLOWSTONE) is 6,649 ft, the highest field elevation in the Montana data. Density altitude can turn a familiar departure into a performance problem on warm afternoons. Airport services are concentrated at the larger towns, not uniformly spread across the map. Montana lists 54 FBOs statewide. KGTF has 2 FBOs. KBZN has 3. Many outlying strips have no listed FBO. M35 (LINDEY'S LANDING WEST) at Seeley Lake is an outlier with a 14,000 ft runway, one FBO and a non-towered operating environment.

KGTF (GREAT FALLS INTL) combines a tower, ILS, a 10,502 ft runway and two FBOs. It is one of Montana’s most useful central-state stops for weather decisions.
KBZN (BOZEMAN YELLOWSTONE INTL) sits at 4,473 ft with a tower, ILS, an 8,994 ft runway and three FBOs. It is a practical mountain-region airport with services.
Where pilots fly
What to know
Montana has 126 public-use airports, but only 6 are towered. That means most flying here depends on non-towered procedures, accurate CTAF work and disciplined traffic scans. Use KBIL, KGTF, KMSO, KGPI, KHLN and KBZN when you want a towered arrival or departure. Expect much of the rural airport network to feel remote.
The elevation numbers matter. KWYS sits at 6,649 ft, 8M3 at 6,534 ft, 4U9 at 6,007 ft, KBTM at 5,551 ft and KEKS at 5,433 ft. Long pavement is not a substitute for performance planning. Warm temperatures, high weight and nearby terrain can make departures unforgiving.
Only 8 Montana airports in the aggregate data list an ILS. The top airport group includes ILS capability at KBIL, KGTF, KMSO, KGPI, KHLN, KBZN, KBTM and KWYS. These fields are the logical anchors for IFR routing, alternates and weather diversion planning across a large state.
Montana has several unusually long runways outside the major towered airports. M35 lists 14,000 ft at Seeley Lake. 8M3 lists 12,007 ft at West Yellowstone. These fields are non-towered, so runway length should be balanced against services, communications, surface conditions and terrain around the departure path.
Anecdotes
Montana’s public-use airport system is heavily non-towered. The state lists 126 public-use airports, with 6 towered fields and 120 non-towered fields.
KHLN (HELENA RGNL) has four runways, the most at any Montana airport in the data. It is also towered, has an ILS and lists a 9,000 ft runway.
KWYS (YELLOWSTONE) is the highest listed public-use airport in Montana at 6,649 ft. It is non-towered, has an ILS, an 8,400 ft runway and one FBO.
Service
Ranked by services count, fuel availability, hours and host airport.
Weather
Montana weather can change sharply with terrain and season. Mountain obscuration, valley ceilings, wind and winter contamination are the main threats. High-elevation airports add performance risk even when skies are clear. KWYS, 8M3, 4U9, KBTM and KEKS all sit above 5,400 ft, so warm-day density altitude deserves a conservative takeoff calculation. Use the ILS airports as practical IFR anchors when ceilings or visibility start to deteriorate.
Training
For training, Montana offers a useful mix. KBIL, KGTF, KMSO, KGPI, KHLN and KBZN provide towered procedures with long runways and ILS capability. The broader airport system is mostly non-towered, so students can also build pattern awareness, CTAF discipline and cross-country judgment in realistic rural conditions.

FAQ
The data ranks KBIL (BILLINGS LOGAN INTL) first among Montana’s top airports. It is towered, has an ILS, a 10,518 ft runway and one FBO. Do not treat that as an annual operations count unless you verify current traffic separately. For flight planning, KBIL is the primary eastern Montana anchor in this directory, with KGTF, KMSO, KGPI, KHLN and KBZN also listed as towered airports.
Montana training planning is split between towered and non-towered environments. KBIL, KGTF, KMSO, KGPI, KHLN and KBZN give pilots radio work in towered operations. The rest of the public-use system is heavily non-towered, with 120 non-towered airports statewide. That mix is useful for private pilot training, cross-country work, mountain awareness and real-world radio discipline.
Brief density altitude first at the high fields. KWYS (YELLOWSTONE) is 6,649 ft, 8M3 (YELLOWSTONE) is 6,534 ft, 4U9 (DELL FLIGHT STRIP) is 6,007 ft, KBTM (BERT MOONEY) is 5,551 ft and KEKS (ENNIS BIG SKY) is 5,433 ft. Long runways help, but they do not remove performance risk. Check climb gradient, weight, temperature and escape terrain before departure.
Montana lists 54 FBOs statewide, but services are not evenly distributed. KBZN has three FBOs. KGTF and KMSO each have two. KBIL, KGPI, KHLN, KBTM, KWYS, M35 and KEKS each list one FBO. Several notable fuel providers include Edwards Jet Center at KBIL, Holman Aviation at KGTF, Great Falls Jet Center at KGTF, Minuteman Jet Center at KMSO and Butte Aviation at KBTM.
Good fly-in choices depend on your aircraft and the season. KGPI (GLACIER PARK INTL) gives a towered, ILS airport near Kalispell with a 9,007 ft runway. KWYS puts you at the highest airport in the state data, with an ILS and one FBO. KEKS offers a 7,600 ft runway at 5,433 ft. M35 is unusual because it lists a 14,000 ft runway at Seeley Lake.
Montana weather planning should focus on mountain obscuration, wind, winter surfaces and density altitude. Western valleys can trap low ceilings while higher terrain blocks direct routes. Central and eastern Montana can be windy, which matters at smaller non-towered fields. In warm weather, high-elevation airports such as KWYS, 8M3, 4U9, KBTM and KEKS deserve conservative takeoff performance planning.
