Glacier Airport adds more nonstop winter flights

Travelers heading to northwest Montana for the 2025–26 winter season will have more options, as expanded air service into Glacier Park International Airport in Kalispell increases access to Whitefish and Blacktail ski destinations via United Airlines.

The winter flight schedule expands from Dec. 18 through April 5.

“This expanded air service makes skiing in Whitefish more accessible during our winter months,” said Zak Anderson, executive director of Explore Whitefish. “More options make it easier for visitors to reach our ski mountains with direct flight options and experience Whitefish and the surrounding community near Glacier National Park.” 

San Francisco service shows the most significant increase over last winter, expanding from weekend-only flights to daily service during the holidays and five flights per week from early January through April 5. 

Seasonal weekend service from Los Angeles returns Dec. 19 and runs through April 5, with evening arrivals into Kalispell on Fridays and Saturdays and return flights to Los Angeles on Saturday and Sunday mornings. 

Chicago O’Hare service expands during the holiday period with daily flights from Dec. 18 through Jan. 5. After early January, service transitions to Saturdays through early February, then increases to five flights per week beginning Feb. 12 and continuing through the end of the ski season. 

Denver remains a primary hub and a year-round route for the region. During the peak holiday period from Dec. 18 through Jan. 5, three daily flights will operate between Denver and Kalispell. Service then continues twice daily through early April.
