The numbers emerging from the global aviation sector this week are not catastrophic, not yet. But they are large enough, and accumulating quickly enough, to reframe the outlook for what was supposed to be a record summer travel season. According to data compiled by Cirium, global airline capacity for May has been trimmed by around three percentage points compared with a year ago, with nineteen of the world’s twenty largest airlines having made some form of schedule reduction. Across the month, that translates to roughly 13,000 cancelled flights and approximately 2mn seats removed from the market. The source of the pressure is by now well-established. The Iran conflict that began in late February 2026 triggered the closure of the Strait of Hormuz, through which roughly a fifth of global oil supply normally passes. Jet fuel costs have more than doubled since February. The International Energy Agency has warned that Europe, the region most structurally exposed to the disruption, may have as little as six weeks of usable aviation fuel reserves remaining. Whatever diplomatic progress is made on reopening the Strait, the supply chain consequences will outlast the conflict itself. No carrier illustrates the severity of the European situation more starkly than Lufthansa. Europe’s largest airline group has cancelled over 20,000 flights between May and October, concentrated heavily on short-haul operations. It shut down its CityLine regional unit entirely, withdrawing 27 aircraft from service, and is accelerating the early retirement of the Airbus A340-600 — a fuel-hungry widebody already living on borrowed time in the fleet. Around 120 daily short-haul services have been grounded to preserve fuel for long-haul routes, where yields are higher and the economics more defensible. Group CFO Till Streichert described the measures as “unavoidable given the sharp rise in jet fuel costs and ongoing geopolitical instability.” The group has also suspended flights to Dubai, Doha and Bahrain until at least the end of May, and added surcharges of up to €50 on long-haul round trips. KLM has cut 80 return services at Amsterdam Schiphol. Air France-KLM has moved in the same direction on surcharges. SAS removed around 1,000 flights from its April schedule. Norse Atlantic has pulled its London Gatwick to Los Angeles service entirely. The pattern across Europe is consistent: Short-haul and marginal routes are being pruned first, fuel levies are appearing on long-haul tickets, and capacity is being concentrated on the routes where demand and pricing power are strongest. The British government’s response has been notable for its pragmatism. Under normal conditions, airlines at major UK airports must use at least 80% of their allocated take-off and landing slots during a season, or risk having those slots reassigned to competitors, the so-called “use it or lose it” rule. Enforced rigidly during a fuel crisis, that rule creates perverse incentives: airlines flying near-empty aircraft purely to protect their scheduling position, burning the very fuel the system is trying to conserve. Airport Co-ordination Limited has updated its guidance to allow airlines to apply for an exemption where fuel shortages are preventing normal operations. UK Transport Secretary Heidi Alexander announced measures allowing carriers to hand back slots proactively without penalty, and to consolidate multiple services on the same route within the same day onto a single flight — provided schedule changes are confirmed at least two weeks before departure. The intent is to allow airlines to plan realistically and lock in revised schedules early, rather than managing disruption in real time at the departure gate. Officials have been careful to state that there is no active jet fuel shortage in the UK at present; the slot changes are explicitly framed as contingency planning, designed to prevent last-minute chaos rather than signal an imminent collapse of the summer schedule. The Asia-Pacific region has received less sustained attention than Europe in coverage of this crisis, but the numbers are meaningful. Cathay Pacific has cancelled approximately two per cent of its scheduled passenger flights between mid-May and the end of June, while its budget subsidiary HK Express is cutting six per cent of frequencies over the same period, with fuel levies of up to $400 imposed on long-haul round-trip fares. Qantas is reducing services to the United States and cutting domestic Australian capacity by around five per cent, with management estimating an additional A$800mn on its fuel bill. Air China has effectively pivoted its international network inward, prioritising domestic routes and suspending a significant number of services to Europe and North America. Air India has reduced its long-haul schedule through July. The regional pattern mirrors Europe’s: Domestic and short-to-medium haul flying is being protected; long-haul routes where the fuel economics have become untenable are the first to go. US carriers source a larger proportion of their fuel domestically and are therefore less directly exposed to the Strait of Hormuz disruption. That relative insulation has not translated into stability for passengers or shareholders. Delta’s chief executive Ed Bastian, announcing an additional $2.5bn in fuel costs for the current quarter, was direct: Any flying operating at the margin of profitability “is likely going to be reconsidered.” United has cut international capacity by 3.5% for the second quarter and raised long-haul fares by up to 20%. Deutsche Bank estimates that non-US airline capacity into and out of American markets will contract by 2.3% year-on-year in the June quarter. The most honest framing of the passenger outlook is this: The situation is serious and actively evolving, but it is not yet a crisis that makes summer travel plans impractical. The cuts made so far are real but measured, an airline trimming five per cent of its schedule is making rational commercial decisions under cost pressure, not approaching operational collapse.What passengers face is a higher probability of schedule changes than in a normal summer, concentrated on a specific category of flying. Short-haul, low-frequency, and low-yield routes are the most vulnerable. The more uncomfortable truth is that the trajectory depends entirely on factors beyond the industry’s control. EasyJet, Virgin Atlantic and Ryanair have each noted that their fuel availability forecasts do not extend comfortably beyond mid-summer. Delta’s Ed Bastian’s framing “this is going to be a test for the industry” is apt. The UK’s proactive slot policy changes suggest one government has drawn the right lessons from past disruption events. Whether airlines and governments elsewhere move with comparable speed and transparency will determine how the summer ultimately unfolds.The author is an aviation analyst. X handle: @AlexInAir.
