Air Canada, Delta and others slash summer flights
- Air Canada has made concrete summer cuts, suspending routes including Toronto–JFK and Montréal–JFK after saying jet fuel prices doubled since the Iran conflict. - Delta hasn’t announced named route suspensions, but it told investors June-quarter capacity will be flat, not growing, after “meaningful capacity reductions.” - This matters because the squeeze is now industry-wide — Cirium says 13,000 May flights and 2 million seats are already gone.
Airlines are doing the thing travelers hate most — quietly making summer smaller. Not every carrier is publishing a big list of canceled routes, but the pattern is real. Fuel got much more expensive, fast, and airlines are cutting the parts of their networks that suddenly look too thin to justify. Air Canada has spelled that out in public. Delta has signaled it in earnings guidance. Across the industry, schedule data already shows a meaningful pullback. ### What actually changed at Air Canada? Air Canada is the clearest example because it named routes and dates. On April 17, updated April 23, it said jet fuel prices had doubled since the start of the Iran conflict and that some flights were “no longer economically feasible.” It suspended Toronto–JFK and Montréal–JFK from June 1 through Oct. 25, Salt Lake City–Toronto from June 30 into 2027, Fort McMurray–Vancouver from May 28, Yellowknife–Toronto from Aug. 30, plus Guadalajara–Montréal and Algiers–Montréal for summer 2026. (aircanada.com) The airline said the total hit is about 1% of planned annual capacity. ### Is Delta cutting too? Yes — but in a more finance-speak way. Delta’s April 8 results said June-quarter revenue should grow on flat capacity, and it tied that to “meaningful capacity reductions” plus efforts to recapture higher fuel costs. Cirium’s schedule analysis also said Delta guided to flat year-over-year capacity in Q2 2026 even though its then-current plan still showed 2.7% growth. Basically, Delta is not saying “we canceled route X,” but it is saying growth that was supposed to happen is no longer happening. (aircanada.com) ### How broad is this now? Pretty broad. Cirium says airlines worldwide cut roughly 13,000 flights and 2 million seats from May 2026 schedules. Looking further out, June through September already show about 9.3 million seats removed across 11 major global markets. Its earlier analysis found almost every one of the 20 largest airlines had cut May schedules, with global May capacity growth dropping to 3.4% from 6.3% before the conflict escalated.

Because this is not just “oil is a bit pricey.” The supply chain for jet fuel itself got squeezed after the effective closure of the Strait of Hormuz at the end of February. S&P Global said wholesale jet fuel prices in northwest Europe averaged $1,521 per metric ton in March — about 97% above the pre-war February average. Air Canada used even plainer language: jet fuel prices doubled. When fuel jumps that hard, a route that was barely profitable turns loss-making overnight.

Airlines usually start with the weakest links — older aircraft, thinner routes, seasonal flying, and markets where they can rebook passengers through hubs. S&P Global said Lufthansa’s cuts were concentrated on loss-making routes flown by older, less efficient planes, while long-haul flying was left alone. That tells you the playbook. Carriers are not trying to shrink everywhere evenly. They are pruning the least efficient branches first. (spglobal.com) ### Does this mean fares jump next? Usually, yes. Fewer seats plus higher fuel bills is the classic recipe. American told investors its second-quarter guidance assumes fuel at about $4.00 per gallon and only partial recovery of those elevated costs. Air France-KLM said its 2026 fuel bill is now expected to rise by about $2.4 billion versus 2025, and it has already leaned on higher ticket surcharges while reallocating capacity. The catch is that airlines do not need every fare to spike — just enough pricing power on the routes that stay. (spglobal.com) ### What should travelers watch now? Watch for aircraft swaps, frequency reductions, and schedule changes that don’t look dramatic until your connection breaks. This is less like a snowstorm and more like a slow drain. Routes disappear. Daily service becomes four-times-weekly service. A cheap nonstop turns into a pricier one-stop. If the fuel crunch lasts into June and July, the industry has already signaled there is room for more trimming. (news.aa.com) ### Bottom line? This is not one rumor-filled travel blog post. It’s a real airline cost shock showing up in real schedules. Air Canada has already cut named routes. Delta has already flattened growth. And the broader market has already lost millions of summer seats. (aircanada.com) (forbes.com)
