The combination of higher jet fuel prices caused by the war in Iran and lower interest from Canadians in visiting the U.S. has led Canada’s largest airlines to trim routes between the two countries—and neither fuel prices nor travel demand show signs of reversing anytime soon.

Key Facts
Jet fuel, which typically accounts for up to one quarter of airlines’ operating expenses, was $3.87 a gallon Monday on the Argus U.S. Jet Fuel Index—up 55% since the U.S. and Israel launched airstrikes on Iran more than seven weeks ago.
Airline bookings from Canada to the US for travel in July are down by 12% year over year, according to Cirium data shared with Forbes that compares bookings made between early January and mid-April 2026 versus the same period in 2025.
The volume of Canadians traveling by air to the U.S. was down 25% in March compared to the same month in 2024, according to data released last week from Statistics Canada.
Air Canada announced Friday it would suspend flights from Montreal and Toronto to New York’s John F. Kennedy International Airport for five months, and between Toronto and Salt Lake City until 2027, citing higher jet fuel costs.
WestJet, Canada’s second-largest airline, which cut more than a dozen Canada-U.S. routes last year, announced it will also further trim routes between the two countries in 2026.
Airlines operating between the two countries collectively cut 320,000 seats between March and October of last year, according to OAG data cited by The Guardian.
What Is Driving The Decline In Travel Demand From Canada?
In early 2025, soon after President Donald Trump ramped up rhetoric about tariffs and making Canada the “51st state,” outgoing Canadian Prime Minister Justin Trudeau urged citizens to reconsider visiting the U.S. The impact was immediate. Flight Centre, Canada’s largest travel agency, told Forbes it saw a 40% decrease in leisure bookings in February 2025 compared to the same month the previous year, and a 20% cancellation rate on prebooked trips to the U.S. Air travel demand between Canada and the U.S. began “collapsing,” with flight bookings for summer and fall declining by over 70%, according to OAG data. Over the entirety of last year, Canadian visitation to the U.S. declined 22%—amounting to a drop of roughly $4.5 billion in visitor spending. Unlike most travel boycotts, which tend to fizzle out over time, the Canadian effort has not lost momentum. Last month, the number of Canadians taking road trips into the U.S.—the most common way of visiting—was down by 35% compared to March 2024, according to data released from Statistics Canada. Nearly a quarter (23%) of Canadian travelers have canceled a previously planned trip to the U.S., according to a Longwoods International tracking study of Canadian travelers. “In my 37 years in the travel industry, I have never seen anything like what the Canadians have pulled off,” Amir Eylon, President and CEO of Longwoods International, told Forbes.
Why Cutting Routes Is A Last-Ditch Move By Airlines
In general, trimming scheduled flights is not the first lever an airline will pull, Mike Arnot, an airline industry consultant at Cirium, told Forbes. “Cutting flights can mean losing access to slots” at busy airports, which are authorized time windows granted to specific airlines to land or take off. Slots are valuable assets, sometimes bought, sold, or swapped between airlines. So, before cutting routes, a carrier is more likely to lower fares to generate demand or, conversely, to raise fares to cover more cost. The next step would be to switch to more fuel-efficient aircraft, “and only then cut flights,” Arnot said. Air Canada did not respond to Forbes’ request for clarity about what drove the cuts.
How Airlines Decide Where To Trim Flights
Carriers needing to cut capacity tend to start by identifying routes with higher costs and lower demand. “Demand shows up in booking trends … It’s all informed by household economics, the local and national economy and, of course, geopolitics,” Arnot told Forbes. “Airlines are likely to trim routes with smaller regional aircraft, which consume more fuel per seat generally,” or cut back on flights with lagging bookings, especially if passengers have alternatives, he said. New York City is served by three major airports—John F. Kennedy, LaGuardia and Newark. If an airline serves all three airports, it can “trim a flight or two per day, and avoid any major impact to options for customers while saving the company money on costs,” Arnot said.
Tangent
Even the most profitable U.S. airlines are compressing capacity in this uncertain environment, with Delta Air Lines announcing it will pause flights on select routes this summer.
