European Airlines Ground Capacity as Gulf Fuel Crunch Forces Schedule Cuts

European carriers are pulling flights from summer schedules and scrambling for alternative jet fuel supplies as the Strait of Hormuz paralysis drags into its second month, with spot prices for Jet A-1 at major European hubs trading well above pre-crisis levels and exposing the continent's lingering dependence on Middle Eastern crude.

KLM this week confirmed the cancellation of 160 services, becoming the largest European flag carrier to formalise schedule cuts since the conflict erupted in late February. Speaking from Dublin, Ryanair chief executive Michael O'Leary said planning beyond the next month had become difficult due to fuel supply challenges within Europe, and warned the low-cost model cannot easily absorb sustained bunker volatility.

JPMorgan analysts have characterised the resulting split as a widening divide across the global airline sector, with premium, well-hedged carriers emerging as relative winners while low-cost and unhedged operators come under pressure, exposing premium-heavy groups such as Lufthansa, IAG and Air France-KLM in a different category to Ryanair, Wizz Air and easyJet. Lufthansa Group has initiated several measures to navigate soaring fuel costs, including the closure of subsidiary carrier Lufthansa CityLine.

European airlines and officials are now turning to the US for replacement jet fuel, with Gulf Coast cargoes arriving at Rotterdam and Hamburg at a premium. The European Commission is understood to be reviewing contingency stockpiling rules that predate the sector's current geopolitical exposure.

Not all the news is grim. Airbus secured 331 firm aircraft orders in March, significantly outpacing Boeing, while EASA this month certified Pratt & Whitney's GTF Advantage engine for the A320neo family, clearing the way for European deliveries later this year, and CFM International signed a LEAP Premier MRO licence with IAG covering both the LEAP-1A and LEAP-1B.

For operators, the summer 2026 question is now binary: fuel markets stabilise by June and schedules hold, or Hormuz remains contested and Europe's aviation map is redrawn around a second shock in two years.
