Europe's Summer Travel in Crisis: Over 13,000 Flights Axed as Fuel Costs Hit Record Highs

Millions of British holidaymakers face summer travel uncertainty as the jet fuel crisis forces airlines to cancel flights, cut routes, and raise fares just weeks before peak season.

The crisis traces back to the outbreak of the Iran war in early 2026 and the subsequent disruption to the Strait of Hormuz, a vital waterway through which roughly 20% of the world's oil supply flows. The blockade has drastically reduced jet fuel supplies reaching European airlines, sending prices to record highs almost overnight.

Jet fuel accounts for around 30% of an airline's total operating costs. With prices more than doubling in a matter of weeks, airlines have been left with little choice but to ground aircraft, cut routes, and pass the costs on to passengers.

Passengers booking today are already paying considerably more. Across UK and European airlines, fuel-related charges have risen by between 15% and 30% since early March, with long-haul routes seeing the steepest increases. Virgin Atlantic has introduced fuel surcharges across its network, and British Airways has warned of further pricing adjustments ahead. Budget carriers flying from UK airports, including popular routes to Spain, Greece, and Portugal, are also seeing fewer cheap seats available as airlines prioritise profitability over low fares. Industry analysts forecast average airfares could rise a further 5% to 10% through the summer months, meaning British travellers who delay booking are likely to pay significantly more than those who act now.

Britain is in a particularly vulnerable position. The UK imports around 65% of its jet fuel, much of it historically sourced through Middle Eastern supply chains now under severe pressure. Industry research has identified the UK as Europe's most structurally exposed market, with domestic airline fuel reserves potentially running low just as the school summer holiday season gets underway in late June and July. Travellers departing from major airports, including London Gatwick, Manchester, and regional hubs, face the highest risk of cancellations and last-minute disruption.

If your flight is cancelled, UK law entitles you to a full refund or a suitable alternative flight under UK261 regulations. Crucially, airlines cannot legally add surcharges to tickets already purchased — your price is locked in at the point of booking. Do not cancel your booking voluntarily, as doing so forfeits your legal protections. Always wait for the airline to act first.

The best advice right now is to book early to secure today's fares, choose ATOL-protected for added financial security, and monitor your airline's updates closely in the weeks ahead. The Crystal Travel team is on hand to help you plan with confidence.
