Where to Fly Into for Glacier National Park — A Complete Airport Guide for 2026
My friend Tom spent three weeks planning his Glacier National Park trip last summer — researching trails, booking lodges, reserving the Going-to-the-Sun Road shuttle. He did everything right. Then he booked the cheapest flight he could find into Great Falls, realized it landed him on the wrong side of a mountain range from the park, and spent an unplanned 2.5 hours driving through highway construction on his first morning.
“Nobody told me there were multiple airports,” he said. “I just assumed one was the same as the others.”
Knowing where to fly into for Glacier National Park before you book is not a minor logistical detail. It shapes which side of the park you explore first, how long you spend in the car, and — depending on the year — whether your flight even lands where you expect.
The Four Airports Worth Knowing
Deciding where to fly into for Glacier National Park comes down to four realistic options for most U.S. travelers. Here’s what each one actually means for your trip.
Option 1 — Glacier Park International Airport (FCA) in Kalispell
Glacier Park International Airport is the main airport for getting to Glacier National Park, sitting just 30 miles from West Glacier. The airport code is FCA, and it sits about 12 miles from Whitefish — one of the most popular gateway towns for park visitors.
Glacier Park International Airport is operational year-round, with flights most commonly connecting through Salt Lake City and Denver. During peak season, you’ll find flights from popular cities like Seattle, Minneapolis, Phoenix, Las Vegas, Los Angeles, Houston, and Chicago. Major airlines serving FCA include Delta, United, Alaska, American, Allegiant, and Sun Country.
The practical advantages are clear: shortest drive to the West Entrance, most rental car options on-site, and a small terminal that moves quickly. The honest trade-offs: limited flight options especially in the off-season, and higher ticket prices compared to larger airports. Book rental cars three to four months in advance for summer trips — they sell out.
One important 2026 note: Glacier Park International Airport is doing phased runway upgrades in July 2026, so the runway will be closed at times. Check the schedule before planning your trip. Missoula is the recommended backup.
Best for: First-time visitors, West Glacier-focused itineraries, travelers prioritizing minimal driving.
Option 2 — Missoula Montana Airport (MSO)
Missoula Montana Airport is located about 150 miles south of Glacier’s West Entrance — approximately a 2.5-hour drive north on US-93 through the beautiful Flathead Valley.
That extra driving time comes with a genuine upside: Missoula often has more flight options and competitive fares, especially from Pacific Northwest cities. The extra 2.5-hour drive from Missoula through the Flathead Valley is scenic and manageable, especially if you’re splitting it with a stop in Polson or Bigfork.
Polson sits on the south shore of Flathead Lake — the largest natural freshwater lake west of the Mississippi. Bigfork is a small arts town 15 miles north. Either makes a legitimate lunch or overnight stop that turns a driving obligation into part of the trip.
Best for: Budget-conscious travelers, Pacific Northwest flyers, anyone who wants to incorporate Missoula or Flathead Lake into their itinerary.
Great Falls International Airport (GTF)
Great Falls is located on the east side of Glacier National Park. If the area of the park in which you want to explore and find less crowd and more ruggedness is Two Medicine, St. Mary, or Many Glacier, then this is a good choice.
Approximately 100 miles east of Glacier’s East Entrance, via US-89, is Great Falls International Airport. GTF airlines are Delta (Minneapolis and Salt Lake City), United (Denver), Alaska and Allegiant.
This is because the east side of Glacier is indeed less visited than the west – Many Glacier is one of the most incredible places in the whole park, and it can still catch first timers off guard, expecting it to be as busy as the Going to the Sun corridor. Depending on how important hiking and viewing wildlife are to you, you can fly into Great Falls from the east.
If you are touring Montana, Great Falls Airport will be a great choice as well, as it’s located roughly halfway between Glacier and Yellowstone National Park.
For: East side explorers, Many Glacier hikers, Montana road-trippers and Glacier/Yellowstone combo trips.
Option 4 — Bozeman Yellowstone International Airport (BZN)
Bozeman Yellowstone International Airport is the busiest in Montana, supplying flights to serve Yellowstone National Park, and is also used by those visiting the Rocky Mountains and Glacier National Park.
Bozeman is roughly 3.5 to 4 hours from Glacier’s West Entrance — a significant drive that most travelers underestimate. However, BZN consistently offers the most flight options, most competitive pricing, and most airline coverage of any Montana airport. If fares to FCA, MSO, and GTF are all high, BZN is worth checking as a fallback.
It pairs naturally with a broader Montana road trip combining Bozeman, Big Sky Resort, Bozeman Hot Springs, and Glacier in a single loop.
Best for: Dual-park trips combining Glacier and Yellowstone, travelers who can’t find reasonable fares elsewhere, Montana road-trippers.
The Rental Car Question — Non-Negotiable
Regardless of where you fly into for Glacier National Park, a rental car is essential. The park’s main attractions are spread over a large area, and public transit options are extremely limited. Book rental cars as early as possible, ideally 3–4 months before a summer visit, as Kalispell rental cars sell out quickly during peak season.
One useful detail from FCA specifically: at Glacier Park International Airport in Kalispell, a kiosk at baggage claim offers commonly-needed rentals like bear spray, camping items, baby carriers, trek poles, and more — a practical stop that saves a separate gear run before you hit the park.
The 2026 Reservation System — What You Need to Know
For 2026, there is no reservation system in place for Going-to-the-Sun Road vehicle entry — a significant change from recent years when timed-entry permits were required. This simplifies logistics but means the road will be busier during peak morning hours. Plan to enter the Going-to-the-Sun corridor before 7 a.m. or after 3 p.m. for the most manageable experience.
Real Travelers, Real Decisions
“I flew into Missoula instead of Kalispell because the fare was $140 cheaper per person for our family of four. We stopped at Flathead Lake for lunch on the drive up, and honestly it felt like the trip started the moment we landed. Zero regrets about the extra driving.”
— Karen M., traveler from Chicago
“We did the east side approach — flew into Great Falls and went straight to Many Glacier. We had the trails almost to ourselves compared to what friends described on the west side. I’d do it exactly the same way again.”
— *David R., hiker from Denver
Frequently Asked Questions
Q: Where should I fly into for Glacier National Park?
For most visitors, Glacier Park International Airport (FCA) in Kalispell is the best answer — it’s 30 miles from the West Entrance and serves major airlines year-round. If fares are high or FCA has runway closures (planned for July 2026), Missoula (MSO) is the best alternative at 2.5 hours from the park.

Glacier Park International Airport (FCA) in Kalispell, Montana is the closest airport, located approximately 30 miles from the West Glacier entrance — about a 40-minute drive.
Q: Is there a difference between flying into the east vs west side of Glacier?
Yes — significantly. The west side (via FCA or MSO) gives easiest access to the Going-to-the-Sun Road, Lake McDonald, and Apgar Village. The east side (via Great Falls/GTF) gives access to Many Glacier, Two Medicine, and St. Mary — areas that are less crowded and equally spectacular.

Yes. A rental car is strongly recommended regardless of which airport you fly into. Book 3 to 4 months in advance for summer visits — Kalispell rental cars in particular sell out quickly during peak season.
Q: Is it cheaper to fly into Bozeman or Missoula instead of Kalispell for Glacier?
Often yes. Both Bozeman (BZN) and Missoula (MSO) typically offer more competitive fares and more direct flight options than FCA. The trade-off is additional drive time — 2.5 hours from Missoula, 3.5 to 4 hours from Bozeman.
Q: Can I combine Glacier and Yellowstone in one trip?
Yes, and Great Falls (GTF) or Bozeman (BZN) are the best airports for a combined trip. Great Falls sits roughly halfway between the two parks on the eastern Montana route.
The Bottom Line
As crucial as picking which trails to hike in Glacier National Park is, however, is finding out where to fly into before you book a flight. In Kalispell, FCA counts on location. MSO in Missoula has a win in its points from fare savings and scenic approach. GTF in Great Falls takes the cake for east side access and combination road trips. BZN in Bozeman is a winner for both flight frequency and dual-park itineraries. When choosing an airport, match it to the itinerary, but not only the airfare search result, the trip begins once you arrive at the airport.
