UK Jet Fuel Shortage — Live Status & Travel Impact

The UK is now Day +15 past the early-May cliff edge that Ryanair CEO Michael O'Leary publicly flagged. As of May 19, 2026, no UK airport — Heathrow (LHR), Gatwick (LGW), Stansted (STN), Luton (LTN), Manchester (MAN) — has issued a formal fuel NOTAM. The Department for Transport's analysis of flight schedules confirms operational impact is contained: roughly 1,200 UK departures have been cancelled across the May 3 – June 14 window, well under 1% of planned flights.

The supply position is tight rather than broken. UK Transport Secretary Heidi Alexander has told media there are "no immediate supply issues" while acknowledging the government is "preparing now to give families long-term certainty and avoid unnecessary disruption at the departure gate this summer." On May 4 the government formally loosened slot-allocation rules so that airlines cancelling due to fuel shortages will not lose their slots — a quiet but significant change that allows up to 10–25% schedule pruning without Brussels-style slot-loss penalties. Heathrow, Gatwick, Manchester and Birmingham are operating under a collective slot-relief regime managed via Airport Coordination Limited.

The reason it has not become a visible shortage is hedging discipline. Jet2 reported on April 29 that it is approximately 87% hedged for summer 2026 at $707 per tonne — versus spot Northwest European jet fuel at roughly $1,840 per tonne, more than 2.6× the locked price. easyJet sits at approximately 70% summer hedging at $706 per tonne. Both carriers have publicly committed to no fuel surcharges on existing summer bookings. Ryanair, BA/IAG and Virgin Atlantic hold the same commitment. The hedges are the firewall.

The proximate cause is the closure of the Strait of Hormuz, the narrow waterway between Iran and Oman through which approximately 20% of global oil and a similarly material share of refined-product trade historically transits. The strait has been effectively closed since February 28, 2026. Per the International Energy Agency's May 2026 Oil Market Report, cumulative global supply losses since February now exceed one billion barrels — the largest oil-supply disruption in the IEA's recorded history.

The UK is exposed because it imports approximately 90% of its jet fuel and historically sourced around 40% of European jet fuel from cargoes that transited Hormuz. With those flows blocked, the UK and other European countries are relying on re-routed cargoes from the United States and West Africa — at roughly six times the normal rate per IEA estimates. The cost of that re-routing is what has pushed Northwest European spot jet fuel to roughly $1,840 per tonne, more than double the pre-conflict baseline of $750 per tonne.

The reason UK passengers have not yet felt this on the ground is twofold: (1) hedging by major UK carriers locked in summer 2026 fuel at pre-crisis prices, and (2) UK airlines hold 5–6 weeks of network supply, with major airports drawing from bunkered reserves that buffer short-term supply interruptions. The Goldman Sachs base case is that those buffers thin through June and July if Hormuz stays closed, with the inventory-low point projected for August.

If you have an existing summer booking, the most important question is whether your airline is hedged. Jet2, easyJet, Ryanair, BA/IAG and Virgin Atlantic all hold public no-surcharge commitments on existing bookings, so your fare price will not rise even if spot fuel costs do. Long-haul flights with smaller wet-lease operators are more exposed; if your trip uses a less well-known carrier as a sub-contracted leg, check their hedging position or consider re-booking with a primary carrier.

If you are planning to book, route choice matters more than carrier choice. Mediterranean leisure routes (Spain, France, Italy, Greece) are first to be cut if airlines need to reduce capacity, because they are leisure-elastic — cancelling these protects business and trunk routes. Trunk routes to North America and major business destinations are last to be cut. The school summer holiday window (late July through August) is when capacity pressure is highest in the Goldman Sachs scenarios.

If your flight is cancelled, UK261 rules apply for UK departures: you are entitled to re-routing on the next available flight at no charge, or a full refund. Compensation for cancellations attributable to "extraordinary circumstances" (which a fuel shortage would likely qualify as) is not normally payable, but the re-routing and refund rights still apply. Document everything in writing and submit any claim through your airline's official channels rather than third-party claim sites.

Travel insurance typically does not cover cancellations from fuel-supply disruption by default — this is a known gap in most off-the-shelf policies. If you are concerned, check your policy wording carefully or ask your provider whether their cancellation cover includes "industry-wide supply disruption" specifically.
