Quick summary
European airfares have jumped 24% year-on-year as jet fuel prices surge following the Strait of Hormuz blockade, with Air France-KLM adding a €100 surcharge on long-haul flights and Lufthansa canceling 20,000 short-haul flights. US carriers including Delta, United, American Airlines, Southwest, and JetBlue have raised checked baggage fees to offset fuel costs, while European airlines ground aircraft on unprofitable routes.
Energy authorities warn Europe has limited jet fuel reserves remaining, with some countries holding coverage of under three weeks. Airlines are filing summer schedule cuts as the crisis enters its third month with no resolution in sight.
Fuel crisis forces airlines to cut flights and raise prices
Jet fuel prices have surged significantly, with reports of doubling due to record crack spreads, forcing European carriers to make immediate operational changes. Lufthansa has grounded aircraft on routes where ticket revenue no longer covers fuel costs, while KLM will cut 160 flights from Amsterdam and Paris next month. SAS canceled over 1,000 flights in April alone.
The €100 surcharge from Air France-KLM applies to all long-haul departures from European hubs, appearing as a separate line item at checkout. EasyJet and other low-cost carriers have announced similar capacity reductions, though specific surcharge structures vary by airline. Industry filings show fuel now represents over 30% of operating costs for European carriers, up from 20% before the crisis.
US airlines have taken a different approach, raising baggage fees rather than adding explicit fuel surcharges. United Airlines warned investors the sustained fuel price environment could add $11 billion in annual costs if conditions persist through year-end. The carrier joins Delta, American, Southwest, and JetBlue in implementing fee increases across their networks.
Regulatory filings reveal airlines are prioritizing long-haul routes where premium cabin revenue can absorb higher fuel costs. Short-haul European flights — particularly those under 90 minutes — face the highest cancellation risk as fuel expenses consume profit margins. Energy authorities monitoring the situation indicate the supply crunch will intensify before any relief arrives.

How the blockade translates to ticket prices
The aviation fuel market operates on crack spreads — the difference between crude oil and refined jet fuel prices. When refineries struggle to source crude or face capacity constraints, that spread widens dramatically. Current spreads have reached levels not seen since the 2020 supply shock, but this time the cause is geopolitical rather than pandemic-related demand collapse.
Airlines hedge fuel costs months in advance, but those contracts are expiring. Carriers now face spot market prices with no hedging protection, forcing immediate pass-through to consumers. The 24% year-on-year fare increase reflects both higher fuel costs and reduced capacity — when airlines fly fewer planes, remaining seats command premium pricing.
Historical precedent offers limited guidance. The 2019 Strait of Hormuz tensions spiked crude oil 5% when Iran seized a UK tanker, leading to temporary 3–7% fare increases on Europe–Middle East routes that resolved within two months through diplomacy. The 1980s Tanker War saw full blockades push oil prices up over 100%, triggering a global recession. The current situation sits between those extremes — more severe than 2019, but without the full economic collapse of the 1980s.
What to do if you have upcoming travel
Airlines are prioritizing long-haul and premium routes where revenue can absorb fuel costs — short-haul European flights face the highest cancellation risk.
- Check flight status daily if traveling within Europe in the next 60 days. Lufthansa, KLM, SAS, and EasyJet are filing schedule changes weekly. Airlines must notify passengers of cancellations, but proactive monitoring gives you first choice of rebooking options.
- Book directly with airlines rather than third-party sites. When schedule changes occur, airline websites and apps offer immediate rebooking tools. Third-party bookings require contacting the agency, adding delays during high-volume periods.
- Consider alternative departure points if flexibility exists. US carriers have raised baggage fees but maintain fuller schedules than European carriers. Transatlantic connections through US hubs may offer more reliable service than intra-Europe connections.
- Document all surcharges at booking. The €100 Air France-KLM charge appears as a separate line item. If the airline cancels your flight, EU261 and UK261 regulations require refund of all fees including surcharges, plus €250–600 compensation if rebooking exceeds four hours.
- Shift to basic economy or fee-free carriers for US travel. Southwest Airlines maintains its two-free-bags policy, offering cost advantage as competitors raise fees. Calculate total trip cost including baggage when comparing fares.
Watch: Energy authority stock reports in early May will reveal whether Europe’s jet fuel reserves have stabilized or continue declining — if reserves fall further, expect systemic summer schedule cuts across major carriers.
Questions? Answers.
Will fuel surcharges be refunded if my flight is canceled?
Yes. Under EU261 and UK261 regulations, airlines must refund all fees including fuel surcharges when they cancel flights. You’re also entitled to €250–600 compensation if rebooking takes more than four hours, unless the airline can prove extraordinary circumstances. US regulations require refunds for cancellations but do not mandate compensation.
Are short-haul or long-haul flights more likely to be canceled?
Short-haul European flights under 90 minutes face highest cancellation risk. Fuel costs consume a larger percentage of ticket revenue on these routes, making them unprofitable at current prices. Long-haul flights generate more premium cabin revenue, allowing airlines to absorb higher fuel costs through surcharges rather than cancellations.
How long will the fuel crisis last?
Resolution depends on Strait of Hormuz reopening, which requires diplomatic or military resolution to the Iran conflict. Energy authorities indicate Europe has limited weeks of jet fuel reserves remaining in some countries. If the blockade persists through summer, expect additional fare increases of 5–10% and expanded schedule cuts beyond current announcements.
Can I claim compensation if my flight is delayed due to fuel shortages?
EU261 and UK261 classify fuel shortages as extraordinary circumstances, which typically exempts airlines from compensation for delays. However, you retain the right to refund if delays exceed five hours. Airlines must still provide meals, accommodation, and rebooking assistance during extended delays regardless of cause.
