Airlines Slash Thousands of Flights as Jet Fuel Prices Double from Hormuz Disruptions

Travelers heading into summer face fewer options, steeper fares and unexpected cancellations after major carriers cut schedules and lowered financial forecasts. Jet fuel costs have surged since the Strait of Hormuz effectively closed to commercial traffic two months ago, turning a vital energy artery into leverage in the stop-start negotiations to end the U.S.-Iran conflict. What began as a regional military escalation now ripples through global supply chains, stock portfolios and family vacation plans.

Lufthansa Group announced it will remove 20,000 short-haul flights from its schedule through October, according to its April 23 statement. The German carrier will cancel less profitable routes and concentrate operations at its Frankfurt and Munich hubs, a shift expected to conserve roughly 40,000 tonnes of fuel. Its CityLine subsidiary is also grounding 27 planes earlier than planned. American Airlines similarly revised its earnings guidance downward, citing sustained high fuel prices with no quick relief in sight. Other international carriers have followed with route trims, fuel surcharges and higher baggage fees.

The trigger sits 50 kilometers wide between Iran and Oman. One-fifth of global oil and LNG shipments normally pass through the strait. After strikes and counterstrikes beginning in late February 2026, commercial traffic halted. Both sides have used access to the waterway as a bargaining chip. Saudi Arabia and the United Arab Emirates maintain limited bypass pipelines—the East-West line and Habshan-Fujairah route—that together offer an estimated 3.5 to 5.5 million barrels per day of capacity, according to the International Energy Agency. That is far below the roughly 20 million barrels that moved through Hormuz daily before the war. Even those alternatives have faced attacks; Iranian strikes in March and April reduced throughput on the Saudi pipeline by about 700,000 barrels per day.

Iraq plans to reopen a 600-mile pipeline to Turkey at an initial 250,000 barrels per day. Iran has a Jask terminal on the Gulf of Oman that could theoretically bypass the strait, yet the IEA describes it as effectively non-operational after limited testing in 2024. New pipelines to Oman, Jordan or Egypt remain years from completion and require political agreements currently in short supply. Fatih Birol, the IEA's executive director, has repeatedly urged countries to diversify energy routes, calling the current vulnerability "a broken record" that now holds a $110 trillion global economy hostage to events in a narrow channel.

Price effects are clear even if exact multiples differ by market and source. Jet fuel costs rose sharply after the closure, prompting Lufthansa to stress that many short-haul routes simply became unprofitable. The airline has secured supplies "for the coming weeks" and is actively procuring additional volumes. European carriers, which import significant Middle East volumes, feel the pressure most acutely. Yet claims of Europe having only "six weeks" of jet fuel or daily economic losses of 500 million euros could not be independently verified across reporting from AP, Reuters or the IEA itself.

Stock prices for airlines and oil-service firms reacted immediately. Broader economic surveys registered declining consumer confidence tied to gasoline prices; one CNBC poll showed President Trump's net approval falling to -18 overall and -21 on the economy, the lowest of his two terms, with majorities saying the Iran conflict is not worth the financial and fuel-cost burden. Independent voters and certain Republican subgroups showed the steepest drops. Still, core support among MAGA respondents remained above 90 percent on both overall performance and the economy.

The central tension remains unresolved: whether this shock represents a short-term price spike that airlines can manage through efficiency or the start of a prolonged supply crunch if Hormuz stays blocked and bypass infrastructure cannot scale. Peace talks continue without a clear timetable. Until tankers move freely again or new corridors are built, carriers will keep trimming schedules. Travelers are already adjusting—postponing trips, paying surcharges, rethinking summer plans. The war that closed a 50-kilometer strait has reminded the world how narrow the margin for energy resilience actually is.
