As of August 2026, Sun Country Airlines discontinued service to 25 destinations and fully exited the Canadian market. This reduction in the network follows the finalization of the company merger with Allegiant Air in May 2026.
Why it matters
The route cuts are a direct result of higher-than-expected pilot attrition following the corporate merger, leaving the airline without sufficient staff to maintain its full schedule. This operational contraction highlights the challenges airlines face in maintaining service levels while navigating significant organizational changes.
Sun Country Airlines reduced its flight and seat capacity by 11.5% this year compared to 2025 levels. The airline currently has 10,515 flights scheduled for the upcoming winter season, a decrease from the 10,884 flights operated during the previous winter period.
The players
Sun Country Airlines
An airline based in Minneapolis that recently finalized a merger with Allegiant Air.
Allegiant Air
An airline that finalized a merger agreement with Sun Country Airlines in May 2026.
Delta Air Lines
A major U.S. carrier that continues to operate flights between Minneapolis and various Canadian cities.
Air Canada
The flag carrier of Canada that remains a competitor on routes previously served by Sun Country.
The details
The airline ceased operations to cities including Buffalo, Pittsburgh, Anchorage, and San Antonio while ending all flights to Vancouver and Toronto. Canadian routes, which the carrier entered in 2022, faced seasonal challenges and competition from legacy carriers like Delta Air Lines and Air Canada.
Timeline
April 2026: The Fort Myers to Appleton route operated for the final time.
May 2026: The merger between Sun Country Airlines and Allegiant Air was finalized.
August 2026: The majority of domestic and Canadian route cancellations were implemented.
September 2026: The airline completed final cancellations for remaining routes.
November 2026 to March 2027: The airline is currently operating its reduced winter schedule.
Travel Outlook
These cancellations reflect a broader trend of post-merger operational consolidation that often forces airlines to shed unprofitable routes to maintain staffing stability. This shift marks a notable retreat for the carrier as it cedes Canadian market share to established competitors.
Travelers who previously relied on these routes should confirm their bookings for the winter season, as availability has been significantly reduced across 25 destinations. Passengers should prepare for potential changes in flight options at the Minneapolis-St. Paul hub and explore alternative carriers for travel to Canada.
The takeaway
Travelers should remain flexible with winter plans as airlines continue to recalibrate schedules following major corporate mergers. Regularly checking flight status and having alternative booking options is essential when navigating a changing network landscape.
