U.S. airlines are making big changes that will affect air travel to Canada.

Some of the top airlines are paring back routes to Canada due to fewer passengers traveling to and from that country.

According to Travel and Tour World, the route changes span multiple airlines, including major carriers like Delta and United. Instead, U.S. travelers are headed to destinations in Europe and the Caribbean instead, the site reported.

United eliminated its “planned Los Angeles – Toronto route” and “trimmed service on its Washington Dulles-Ottawa and Washington Dulles-Montreal routes,” the site reported on June 21.

Meanwhile, between April and June, Delta Air Lines and other U.S. airlines “cut back transborder routes by 4.4 percent between April and June 2025,” affecting routes like Atlanta to Toronto, Detroit to Calgary, and Minneapolis to Vancouver, the site reported.

This comes as air travel between the two countries has dropped. It works both ways too. In the midst of rhetoric directed from the U.S. toward their country, more Canadians are not traveling to the U.S., and Air Canada was also cutting routes, Business Traveler USA reported.

According to the Globe and Mail, some U.S. states are “seeing a drop of up to 60 per cent in visitors from north of the border.”

The decreases were felt as far back as March, when Daily Voice reported that “forward bookings between the U.S. and Canada are down more than 70% compared to 2024.” The decreases are most significant in the summer months when travel escalates, the site reported.

“For all scheduled airlines operating between the United States and Canada, any fall in consumer confidence and subsequent changes to planned travel are a concern, especially in such a large market and when taking place at such short notice,” OAG senior analyst John Green wrote in a blog post. “Unfortunately, the law of unintended consequences is once again impacting the airline industry, adding to what had already become a softening market.”

In May 2025, “Canadian-resident return trips by air from abroad stood at 1.6 million, down 3.7% from the same month one year earlier. Although Canadian-resident return trips from overseas countries increased (1.1 million; +9.8% from May 2024), return trips by air from the United States declined in May 2025 (488,800; -24.2%), Statistics Canada reported.
