Quick summary
Global jet fuel prices have more than doubled to $195 per barrel since the Iran war began, with oil hitting $109 per barrel as the Strait of Hormuz remains militarily closed. UK travelers face immediate 20–50% fare increases on European routes and surcharges up to £360 on long-haul business class, with airlines passing costs directly to passengers as fuel hedging expires.
Europe’s jet fuel stockpiles — typically holding several months’ supply — are depleting daily with no imports flowing through the Strait, which previously supplied 40% of the continent’s jet fuel. The International Energy Agency reports a critical inventory update due April 25 that will determine whether widespread capacity cuts follow.
Fuel crisis forces immediate fare hikes across UK carriers
The closure of the Strait of Hormuz has severed 40% of Europe’s jet fuel supply, triggering the sharpest fare increases UK travelers have seen outside pandemic-era disruption. Virgin Atlantic imposed a £50 surcharge on economy tickets last week, with premium economy climbing £180 and business class £360. Air France and KLM followed with €50 increases, bringing total fuel surcharges to €100 on European routes.
Jet fuel accounts for roughly 30% of airline operating costs — the single largest expense. With prices doubling in six weeks, carriers have exhausted fuel hedging contracts that locked in lower rates through March.
Oil barrel prices rose over 40% in the past two weeks from the Middle East conflict, impacting summer travel costs immediately. The US jet fuel index hit over $4.60 per gallon, up from $2.50 before the Iran war, leading to airline fare increases and surcharges across transatlantic routes.
Passengers with existing bookings are protected from retrospective fare increases — once paid, airlines cannot demand additional ticket costs. However, industry analysis shows carriers are finding alternative revenue streams through baggage fee increases and ancillary charges applied at check-in.
| Carrier | Economy surcharge | Premium economy | Business class |
|---|---|---|---|
| Virgin Atlantic | £50 | £180 | £360 |
| Air France/KLM | €100 (£87) | €100 (£87) | €100 (£87) |
| British Airways | Data pending | Data pending | Data pending |
Europe’s jet fuel buffer shrinks as Strait remains closed
European countries typically maintain several months of jet fuel inventory, but daily depletion without resupply is pushing the continent toward critical shortages. The International Energy Agency’s director warned last week that Europe has “maybe six weeks” of remaining jet fuel supplies — a timeline that would place potential shortages in late May or early June, peak summer travel season.
No jet fuel has passed through the Strait since the war outbreak, according to energy market analysts. This represents an unprecedented supply disruption — the 2019 Stena Impero tanker seizure briefly halted 20% of global oil transit and caused 15% jet fuel price increases in Europe within days, but the Strait never fully closed.
Airlines are already responding with capacity cuts. Swedish carrier SAS cancelled 1,000 flights in April following several hundred March cancellations. United Airlines announced 5% flight reductions for the second and third quarters of 2026, while KLM cut 160 flights for the coming month. British Airways suspended multiple Middle East routes, and Virgin Atlantic permanently scrapped its London–Riyadh service earlier this month.
The situation mirrors broader fuel supply pressures affecting European carriers — Aer Lingus and Ryanair face potential summer flight cancellations as Ireland’s jet fuel buffer shrinks alongside continental Europe’s stockpiles.

Package holiday surcharges hit existing bookings
A clause in UK Package Travel Regulations allows tour operators to impose surcharges up to 8% of total holiday cost without offering free cancellation — and fuel price increases qualify as a trigger. Travelers who booked package holidays months ago at lower prices now face potential hundreds of pounds in additional charges as operators invoke this provision.
The regulation covers three scenarios: destination taxes, currency fluctuations, and fuel cost increases. With jet fuel doubling since late February, package operators have clear grounds to apply the maximum 8% levy. A £3,000 family holiday to Spain could see a £240 surcharge added weeks before departure.
Passengers holding ATOL-protected bookings have recourse if surcharges exceed the 8% threshold — contact the Civil Aviation Authority’s ATOL hotline at 020 7955 6978 to dispute excessive charges. The CAA’s passenger rights framework requires operators to justify surcharges with documented cost increases and limits total price adjustments to 8% of the original booking value.
For travelers without package protection, airlines cannot retrospectively increase paid ticket prices. However, ancillary fees remain vulnerable — American carriers have raised checked baggage fees by $10 for first and second bags, with third bag fees jumping $150. These increases affect passengers who add luggage close to departure, a common practice that now carries significantly higher costs.
Understanding why flight prices are rising across multiple regions helps travelers anticipate similar patterns on Asia-Pacific routes, where fuel represents an even larger cost share due to longer distances.
What to do
The IEA’s April 25 inventory report will determine whether airlines implement emergency capacity cuts — travelers with summer bookings must act before that data triggers further reductions.
- Existing summer bookings: Verify ATOL protection at atol.org.uk/check-an-atol and contact your tour operator within 24 hours if fuel surcharges appear. Demand written justification for any charge exceeding 8% of original cost — operators must provide documentation under Package Travel Regulations.
- Planning new trips: Book European routes immediately through airline direct channels to lock current fares before the April 25 IEA report. London–Barcelona economy returns currently range £180–250, up from typical £120 pre-crisis. Avoid Middle East connection points — Gulf hub routings add 15% fuel burn through reroutes.
- Long-haul travelers: Monitor Foreign Office travel advisories at gov.uk/foreign-travel-advice for Middle East airspace updates. If your routing transits Dubai or Doha, contact your carrier’s rebooking line to explore European hub alternatives — British Airways and Virgin Atlantic are offering vouchers for voluntary route changes on affected bookings.
- Package holiday holders: Request fuel surcharge waivers in writing from operators like TUI (0203 451 2688) or Jet2holidays — some are absorbing costs on bookings made before March 1. If refused, file complaints with ABTA at abta.com/consumer-complaints before accepting charges.
Watch: The IEA’s European jet fuel inventory update on April 25 will reveal whether stockpiles have fallen below 50 days — if confirmed, expect mandatory surcharges and 15–20% long-haul capacity cuts from UK carriers through summer.
Questions? Answers.
Can airlines charge me more for a ticket I already bought?
No. Once you’ve paid for a flight ticket, the airline cannot retrospectively increase the fare or add fuel surcharges to that specific booking. However, package holiday operators can add surcharges up to 8% of total cost under UK Package Travel Regulations if fuel costs rise significantly after booking.
What happens if my flight gets cancelled due to fuel shortages?
If your flight is cancelled more than 14 days before departure, you’re entitled to a full refund or alternative flight under UK law, but not compensation. Given current elevated fares, accepting an alternative flight may be more economical than rebooking at today’s prices. Airlines must offer you the choice of flying as soon as possible or at a later date that suits you.
How long will these fuel price increases last?
Duration depends on Strait of Hormuz reopening and Middle East conflict resolution. The IEA reports Europe has approximately six weeks of jet fuel reserves as of mid-April 2026. If the Strait remains closed beyond late May, expect sustained high prices and potential capacity cuts through summer. Historical precedent from 2019 showed prices normalized within 8–12 weeks after supply resumed.
Should I cancel my summer holiday and rebook later?
Cancelling now means rebooking at current elevated prices with no guarantee of future decreases. If you hold an ATOL-protected package with surcharges below 8%, keeping the booking is typically more economical. For flight-only bookings, monitor the April 25 IEA inventory report — if stockpiles remain above 60 days, prices may stabilize rather than climb further.
