The main issue confronting air transport right now is the fuel shortage. With the conflict in Iran and the closure of the Strait of Hormuz, the price of kerosene in Europe has reached an all-time high of roughly $1,900 per ton, up nearly $300 in a single day. Europe imports 25% to 30% of its kerosene from the Persian Gulf, and jet fuel costs were still roughly 40% higher than pre-war levels in mid-June. Airlines have responded with targeted fuel rationing cuts: Lufthansa (which includes ITA Airways, formerly Alitalia) canceled approximately 20,000 flights between May and October and is suspending flights to Abu Dhabi, Amman, Beirut, Dammam, Riyadh, Erbil, Muscat, and Tehran until October 24; Turkish Airlines has canceled over 3,000 flights on 23 routes; KLM has scheduled 160 fewer flights in Europe; and the already-fragile Spirit Airlines has ceased operations. Italian airports have also felt the pressure: Brindisi has set a 5,000-liter fuel limit per aircraft, Reggio Calabria 3,000 liters, and similar restrictions have been imposed at Linate, Venice, Treviso, and Bologna. However, airlines and institutions insist that supplies for July and August are adequate, citing increased imports from the United States, Norway, West Africa, and South America, as well as refineries such as Repsol in Spain, which have expanded kerosene production by 20-25%.
