Spain’s summer flight outlook is tight

Spain’s main refiners say jet fuel supplies are secure through the end of May, but officials are warning that summer shortages could still hit June through August if the global fuel squeeze deepens. The pressure comes as the Iran conflict and a possible Strait of Hormuz blockage push up oil and jet fuel prices.

Industry Minister Jordi Hereu said airlines are flying on cheaper fuel they bought earlier, but fare increases are likely once those stocks run out. Aena, Spain’s airport operator, said it's monitoring supply closely and hasn't reported immediate shortages.

Travelers face higher fares and possible cuts

The sharpest risk is for travelers moving through major hubs like Madrid, Barcelona and Malaga, plus busy UK-Spain routes. Sources cited fare jumps of 24% on some economy tickets, with fuel surcharges already appearing on some airlines.

Digital nomads and expats who book late could feel the squeeze on peninsula trips, island hops and return flights. Lufthansa has already cut 20,000 short-haul flights through October to save fuel, a sign airlines are trimming schedules where costs bite hardest.

Book early and watch airline rules

Spanish officials are urging travelers to book now to lock in lower prices and refiners Repsol, Moeve and BP say current supplies should hold through May. After that, airlines may pass on higher fuel costs through surcharges such as €14 ($15) per passenger on Volotea and €50 ($54) round-trip on Air France-KLM.

Check rebooking and refund rules before buying, especially if your itinerary depends on summer connections. Read our full Spain guide for the complete picture.
