Jet Fuel Shortage 2026: Will Flights Be Cancelled This Summer? Honest Answer for Travellers

Your summer trip is unlikely to be canceled outright — but risks have crept up, and fares are climbing.

Here’s which routes are exposed, what your ticket will really cost, and what to do if things go wrong.

What’s Driving the Crisis Right Now

• UK airlines have been given the green light to cancel or consolidate flights to conserve jet fuel under new rules announced on 3 May 2026
• The Strait of Hormuz remains effectively closed, with shipping traffic down roughly 95 percent since Iran declared the strait closed on 4 March 2026
• Jet fuel prices have more than doubled since February, with the global average above US$181 per barrel and European spot prices reaching US$187 or higher
• The Middle East supplies about 75 percent of Europe’s net jet fuel imports, much of it routed through the now-closed Strait of Hormuz
• European jet fuel stocks are projected to fall below the critical 23-day threshold in June if the strait stays shut

Which Summer Trips Are Actually at Risk

The shortage is geographic, not global. Where your flight takes off from matters more than which airline you fly. A Dublin-to-Malaga hop sits on a very different fuel supply than a Dubai-to-Mumbai service, even if both happen on the same Tuesday.

High Risk: UK and Northern European Short-Haul

UK departures are the most exposed because Britain imports most of its jet fuel and has little domestic refining capacity. Intra-European short-haul is next because these routes are the cheapest for airlines to drop when fuel is tight.

UK airlines have now been formally cleared to cancel or consolidate flights to conserve jet fuel, with at least two weeks’ notice required. Cancellation rates have stayed within normal ranges so far, but that could change quickly.

Recent confirmed cuts:

• Lufthansa Group — 20,000 cancellations from April through October, mainly short-haul from Frankfurt, Munich, Zurich, Vienna, Brussels, and Rome
• KLM — 160 intra-European flights to and from Schiphol cut in May
• Transavia (Air France-KLM group) — around 400 flights canceled across May and June
• Turkish Airlines — 18 international destinations suspended from May and June, including Hurghada, Havana, Aqaba, Kirkuk, Najaf, Leipzig/Halle, and multiple African destinations
• SAS — roughly 1,000 services canceled in April

If you’re flying this summer with one of these carriers, Wego has airline-specific guides:

• Ryanair fuel shortage impact — well hedged, no cancellations yet, but 5 to 10 percent summer cuts flagged if the crisis continues
• easyJet fuel shortage impact — UK departures most exposed
• Jet2 fuel shortage impact — currently operating as scheduled
• KLM flight status 2026 — intra-European frequency cuts
• Lufthansa flight status 2026 — 20,000-flight cancellation list

Practical steps before you fly:

• Book a flexible or refundable fare, not the cheapest basic economy
• Avoid tight connections of under two hours
• Have a backup carrier in mind, ideally one routing through a Gulf or Middle Eastern hub

Medium Risk: Europe Long-Haul and Secondary Leisure Routes

Full-service European carriers like British Airways, Lufthansa, and Air France are more protected on long-haul because those routes earn more per seat.

Secondary leisure routes, smaller Greek islands, regional French airports, and smaller Italian destinations may see quiet frequency cuts. Italian airports have already begun jet fuel rationing at smaller fields.

If this is your trip, expect the flight to operate but don’t be surprised by schedule changes. Build in a buffer day at the start of your trip if you’re connecting to a cruise, tour, or event.

Lower Risk: GCC and Middle East Hubs

Flights out of Dubai, Doha, Abu Dhabi, and Riyadh are running reduced but stable schedules.

These hubs sit close to production, so outright cancellations are less likely than in Europe. Emirates, Qatar Airways, and Etihad have added fuel surcharges but kept their networks largely intact.

If this is your trip, book with confidence but expect to pay more. Wego tracks live status for Emirates and Qatar Airways.

Mixed Risk: Asia-Pacific

Carriers routing through Singapore, Kuala Lumpur, and Bangkok have diversified fuel supply and are less exposed to the Strait of Hormuz disruption. Singapore Airlines and similar operators are running full summer schedules.

Cathay Pacific is canceling around 2 percent of scheduled passenger flights from mid-May through end-June, and HK Express is cutting around 6 percent. All Cathay flights to and from Dubai and Riyadh are also canceled through 30 June, with Tel Aviv services suspended.

Air India is also pulling roughly 100 flights from its long-haul schedule through July, cutting services to London, New York, Paris, Sydney, and other major cities as fuel costs push routes into loss-making territory.

Wego has a dedicated list of airlines not raising fares despite the crisis, which still leans heavily Asian, plus a Cathay Pacific fuel surcharge breakdown and a Singapore Airlines fuel surcharge guide.

High Risk: Ultra-Low-Cost US Carriers

Spirit Airlines began a “wind-down” on 2 May 2026 and has canceled all remaining flights, citing the doubling of jet fuel prices during the Iran war. Fuel costs hit roughly US$4.51 per gallon by late April — well above the US$2.24 per gallon assumed in Spirit’s restructuring plan.

If you have a Spirit booking, the airline says it will automatically issue refunds to passengers who paid by credit or debit card. You can also contact your card issuer or travel insurer. United, Delta, JetBlue, and Southwest have capped fares for displaced Spirit passengers at around US$200 one way.

What Your Ticket Will Really Cost

Even if your flight operates perfectly, it will almost certainly cost more than you budgeted. Fuel surcharges are layered on top of base fares, and most travelers don’t see them until checkout.

IATA estimates fares could rise 8 to 9 percent on average across affected markets, with sharper spikes on long-haul. United Airlines is reportedly weighing 15 to 20 percent hikes on transatlantic routes, and European jet fuel prices are now more than double last year’s levels.

Surcharges to Budget For

Here is roughly how much extra to expect per ticket, based on announced surcharges:

When to Book

Waiting for fares to drop is not a winning strategy this summer. Cathay Pacific is reviewing surcharges every two weeks, and most carriers have flagged more increases ahead.

The general industry guidance, including from Ryanair, is to book now and lock in today’s fare. Surprise fuel fees added after booking are not normally allowed, so a confirmed ticket is your best hedge.

If Your Flight Does Get Canceled

If your flight is canceled, you almost always get your money back. Whether you get extra cash compensation on top depends entirely on where you’re flying from. Wego has airline-specific cancellation guides for Ryanair, KLM, easyJet, Cathay Pacific, and Qantas.

EU and UK Departures

Under EU Regulation 261/2004 and the UK’s UK261, you are entitled to a full refund within seven days, free rebooking on the next available flight, or rebooking at a later date that suits you.

You may also be owed cash compensation of €250 to €600 depending on flight distance, but airlines will almost certainly cite the war-driven fuel shortage as an “extraordinary circumstance” that exempts them from paying it.

The new UK rule that lets airlines cancel flights to conserve fuel requires at least two weeks’ notice, which means cash compensation under UK261 is unlikely to apply for those specific cuts. Expect the refund. Don’t count on the cash bonus.

Departures From Other Regions

Outside the EU and UK, your rights come from the airline’s own contract of carriage and the local aviation regulator. Gulf carriers including Emirates and Qatar Airways typically offer full refunds or free rebooking when they initiate a cancellation. Check the airline’s website for the specific policy before calling.

Travel Insurance and What to Do at the Airport

Check your travel insurance policy now, not after the cancellation. Many standard policies exclude “acts of war,” which is how the Iran conflict is classified — so verify your policy explicitly covers conflict-related flight cancellations before relying on it. Premium credit cards often include trip interruption cover that can fill gaps.

If you find out about a cancellation at the airport, head to the airline’s rebooking desk and call the airline at the same time — take whichever option comes through first. Keep every receipt for food, transport, and hotel: these are often reimbursable under EU261 or your insurance.

How to Book Smart for Summer 2026

The right summer booking strategy is not to delay and hope. Book now with protection built in: pick a mid-tier fare with free changes rather than the cheapest basic economy.

Route through a Gulf hub (Dubai, Doha, Abu Dhabi) or a Southeast Asian hub (Singapore, Bangkok) rather than fuel-constrained UK or Northern European airports. Know your next two alternative flights to the destination before departure day.

Recheck your flight status seven days before travel, reconfirm 48 hours out, and check again the morning of your flight.
