Jet‑fuel squeeze warning

Europe’s airport operators are warning that the fuel problem first seen in northern Italy could spread across the continent within weeks, with the risk window landing in May just as summer schedules start to fill up. The trigger is not a refinery fire in Europe but a supply shock much farther away: disruption through the Strait of Hormuz, the narrow shipping lane that carries around one fifth of global crude exports. (aci-europe.org, euronews.com) Jet fuel works like a just-in-time supply chain for airports: planes land, refuel, and leave, while storage tanks on site only cover a limited buffer. When tanker deliveries slow down for even a few days, airports do not have many easy substitutes, because aircraft need certified aviation fuel and cannot simply switch to another product. (euronews.com, enac.gov.it) Italy is the first place where that abstract risk has turned into operating limits. Italy’s civil aviation authority said on April 5 that fuel-supply restrictions were already affecting four airports, and Euronews identified them as Bologna, Milan Linate, Treviso, and Venice, with priority given to medical, state, and long-haul flights. (enac.gov.it, euronews.com) That matters because northern Italy is not a fringe corner of the network. Assaeroporti, the Italian airport association, says Italy’s airports handled 14.2 million passengers in February 2026 alone, up 5.6% from a year earlier, so even a short fuel cap can ripple into missed rotations, aircraft swaps, and delayed departures across multiple countries. (assaeroporti.com, assaeroporti.com) Europe is especially exposed because its airport system is already running busy again. Airports Council International Europe said Europe’s airports handled a record 2.6 billion passengers in 2025, and the group represents airports facilitating more than 95% of commercial air traffic in Europe, which means a supply squeeze at a few hubs can spread fast through the wider schedule. (aci-europe.org, aci-europe.org) The price signal is already flashing red before the physical shortages become widespread. Euronews reported on April 7 that jet-fuel prices had jumped 95% since February 28, after the United States and Israel launched military attacks against Iran and the war fed into an effective closure of the Strait of Hormuz. (euronews.com) Airlines usually respond to a fuel spike in three steps, and none of them are good for travelers. First they add surcharges or raise fares, then they cut weaker routes, and then they protect the most profitable or hardest-to-replace flights, which is why Italian restrictions are already favoring long-haul and medical services over shorter trips. (euronews.com, euronews.com) One reason airport operators are sounding the alarm now, on April 10, is the calendar. May is when school breaks, holiday travel, and summer timetable ramp-ups begin in parts of Europe, so a shortage that would be painful in February becomes much harder to absorb when planes, crews, and airport slots are already tightly booked. (telegraph.co.uk, aci-europe.org) The awkward twist is that Europe has spent the past two years talking about cleaner aviation fuels while still depending on large volumes of conventional jet fuel right now. Italy’s own Sustainable Aviation Fuel roadmap says sustainable aviation fuel still covers only about 0.2% of global needs and costs three to seven times as much as conventional jet fuel, so it cannot plug a sudden supply hole in spring 2026. (enac.gov.it, aci-europe.org) If the shipping disruption eases, this story can fade as quickly as it appeared, because fuel systems recover once tankers and refineries start flowing normally again. If it does not ease, the first signs most travelers will notice are not grounded airports on television but higher ticket prices, thinner short-haul schedules, and more last-minute changes on routes that looked perfectly normal when they were booked.
