Flying to Glacier in 2026? Kalispell Airport Closure & travel Planning Guide
If visiting Glacier National Park is on your calendar for summer 2026, there is one logistical detail worth planning around early: Glacier Park International Airport (FCA), will operate on limited schedules throughout July due to runway construction.
This is routine infrastructure maintenance designed to ensure long-term safety and reliability, but it introduces temporary constraints that can influence how and when you travel.
Here’s what that means in practical terms.
Why Construction Is Happening
According to Glacier International Airport, the main runway is undergoing resurfacing after reaching the end of its typical service lifespan. Runway pavement generally lasts 15 to 20 years, and FCA’s surface was last rehabilitated in 2009, making the upgrade necessary to prevent deterioration and maintain safe operations.
July was selected because weather conditions offer the highest likelihood of dry temperatures required for construction standards, minimizing the risk of extended or unpredictable closures.
Closure Schedule
Glacier International Airport reports that, construction impacts will occur:
July 6 through July 31, 2026
During this period:
Runways close Mondays at 6 p.m.
Remain closed through Friday morning at 10 a.m.
Reopen Fridays through Mondays
This schedule repeats across four consecutive weeks, allowing flights to continue during peak weekend travel demand. Glacier County reports, about sixty percent of typical service is expected to operate while construction is underway, though weekday access will be significantly reduced.
In September, construction will be limited to nightly closing and not predicted to interfere with flight schedules.

What Travelers May Experience
Limited flight availability
Schedule adjustments from airlines
Potential price increases
Higher demand on weekend routes
Travel authorities, including the Official Western Montana Travel and Tourism, notes that ticket pricing and scheduling may shift as airlines respond to reduced operational capacity. This does not make travel impossible. It simply shifts the planning window.
Alternative Arrival Strategies
Visitors have several options:
Book weekend arrivals when service is strongest
Monitor airline schedule updates
Allow flexibility in itinerary timing
Nearby regional airports remain viable alternatives:
Missoula Montana Airport (2.5 hours drive)
Great Falls International Airport (4 hours drive)
Spokane International Airport (4.5 hours drive)
Calgary International Airport (5 hours + border crossing)
For some travelers, incorporating a scenic drive from another airport becomes part of the trip experience rather than a disruption. Flying in and out of Canada also would allow exploration of Banff National Park.
Consider taking the Amtrak’s Empire Builder in for a unique experience by train, or better yet, combine routes.
How This Affects Glacier Trip Planning
Early awareness is more important than usual for summer 2026. Travelers building structured itineraries, especially first-time visitors, may benefit from:
Building time buffers
Considering multiple entry routes
Booking flights earlier than typical
Access to the region remains intact. The park itself is unaffected by runway construction, and weekend air service is being prioritized to maintain visitor flow. Be sure to seek guidance on access, transport, road closures, wildlife alerts from the National Park Service.
