Why your summer 2026 flight could cost more...
...and what to do about it now
Oil back up near $90 a barrel, energy bills up 13% this month, and jet fuel still running well above pre-conflict levels. Five months in, here's what it actually means for the cost of your holiday, and what you can do about it.
Short on time? Let us summarise this guide for you.
Brent crude has swung wildly over five months: from around $70 before the conflict, up to a peak of $126 in late April, back down to roughly $71 in early July as ceasefire talks progressed, and back up to around $90 now that fighting has resumed. The one genuinely reassuring update is on European short-haul fares: despite fuel costs squeezing airline profits hard, easyJet and Ryanair have actually kept fares broadly flat, in Ryanair's case even lower year on year, because demand has been softer and later than expected, and both airlines chose to compete on price rather than pass costs straight through. Ryanair's boss has also said the risk of a European jet fuel supply shortage, a real worry back in the spring, has now receded. The picture is worse away from the ticket price: the energy price cap rose 13% to £1,862 a year from 1 July, inflation is running at 2.6% and the Bank of England expects it to peak nearer 3.2% later this year, and the Bank has held interest rates at 3.75% for a fifth time. Long-haul travel via Gulf hubs remains the most exposed to cost and disruption. For most UK holidaymakers heading to Spain, Greece, Portugal, Turkey or Italy, the honest read is that a holiday will cost a little more this year, mainly through the wider cost of living rather than a big jump in the flight itself, and the case for delaying a booking to avoid fare rises is weaker than it looked back in April.
Before the conflict began on 28 February 2026, Brent crude oil was trading at around $70 a barrel. It has swung enormously since. Prices surged past $100 within days of the initial strikes and the near-closure of the Strait of Hormuz, through which a substantial share of the world's oil passes, before eventually peaking at more than $126 a barrel on 30 April. As ceasefire talks progressed through June, prices fell all the way back to around $71 by early July, close to where they started. That calm didn't last: when the ceasefire collapsed and fighting resumed in early July, Brent climbed back to the high $80s and low $90s, where it remains at the time of writing, around $90 to $92 a barrel.
That matters to your holiday because jet fuel is refined from crude oil, and jet fuel typically accounts for around a fifth of an airline's operating costs. Since the conflict began, jet fuel prices have consistently risen faster and further than crude itself, roughly doubling at points versus a one third rise in crude, because refiners have added extra margin on top during periods of acute supply uncertainty. Even now, with Brent well below its April peak, jet fuel costs remain well above where they were before the conflict.
The chain from oil well to your ticket price runs roughly like this:
That last step is the genuine surprise of the past few months: several airlines have chosen to hold or even cut fares rather than pass rising costs straight through, because demand has been softer and bookings later than expected. We cover what that has actually meant for fares below.
Not all flights have been equally exposed, and the picture has turned out somewhat differently to what airlines themselves predicted back in the spring.
For the most common UK holiday flights, to Spain, Greece, Portugal, Turkey, Italy and similar destinations, the fare impact has been smaller than airlines themselves expected. easyJet and Ryanair both reported sharp falls in profit for the April to June quarter because of fuel costs, but rather than passing those costs on in full, both airlines cut or held fares to keep filling seats amid softer, later booking patterns. Ryanair's average fare actually fell slightly year on year. That's genuinely good news if you're booking a European break, though it isn't guaranteed to hold: hedging cover thins as the year goes on, and if demand picks up into late summer and autumn, some of that discipline could ease.
If your holiday involves flying through Dubai, Doha or Abu Dhabi, as a large share of UK long-haul travel does, you continue to face a double problem: route disruption from the airline suspensions covered in our safety guide, and higher fuel costs on the routes that are operating. Long-haul fares on Gulf-routed journeys have remained noticeably higher than before the conflict, and that's likely to persist for as long as European and Asian carriers keep their own suspensions in place into the autumn.
Routes to the Americas, West Africa, and destinations served by routings that avoid the Gulf continue to face fuel cost pressure from the still-elevated price of jet fuel, but without the compounding effect of route disruption. Expect some upward pressure on fares here, though nothing close to the scale seen on Gulf-routed long-haul.
Fuel hedging is the airline industry's key defence against oil price spikes. Airlines use financial contracts to lock in future fuel prices months, sometimes years, in advance. When oil jumps suddenly, a well-hedged airline barely feels it in the short term. An unhedged one is immediately exposed. Five months in, here's where the major UK-relevant airlines currently stand, based on their most recent quarterly results.
The practical read-through: easyJet and Ryanair have both absorbed a real profit hit rather than pass the full cost on to passengers, at least for now. That's a genuinely different outcome to the one predicted back in the spring, when fare rises of several percent were widely expected on European short-haul. British Airways and its IAG siblings face more upward pressure as hedge cover falls further into the year, and airlines with thinner protection, such as Wizz Air and SAS, remain the most exposed if oil prices climb again.
One important nuance remains true regardless of any single airline's choices: jet fuel prices have consistently moved further than crude oil prices throughout this conflict. Even a period of calmer oil prices, like the one seen in late June and early July, doesn't fully unwind the higher cost airlines are paying for fuel itself.
If you have an existing booking, here is the most important thing to know: your price is fixed. Airlines cannot retrospectively add fuel surcharges to tickets you have already bought. Whatever you paid when you booked is what you pay. easyJet has publicly and repeatedly confirmed it will not add surcharges to existing bookings, a commitment it has maintained throughout the conflict.
This applies whether you booked in March or last week, and regardless of what has happened to oil prices since. Your booking is a contract at the price agreed.
What can change after booking is optional extras. Car hire companies or hotels may adjust their pricing independently, and some third party "fuel surcharge" fees on package bookings can occasionally be subject to revision under contract terms. Read your booking conditions carefully if you're concerned about any of these.
The conflict's financial impact on UK households extends well beyond the price of a plane ticket, and this is where the squeeze has actually been felt most, rather than in flight prices themselves.
Ofgem's energy price cap rose by 13% on 1 July 2026, from £1,641 to £1,862 for a typical dual-fuel household paying by direct debit. Ofgem has been explicit that the increase reflects higher wholesale gas prices caused by the conflict. The next cap, covering October to December, will be announced by 26 August 2026; early industry predictions vary, with some suggesting a modest fall if wholesale prices stay where they are, but nothing is confirmed and the situation remains sensitive to further escalation.
UK forecourt prices rose sharply through the spring and remained elevated through the summer as the conflict has dragged on. Fuel industry experts continue to note that supermarkets typically hold out longer before passing on wholesale price rises than independent dealers, so filling up at a supermarket forecourt may still save a few pence per litre.
CPI inflation stood at 2.6% in June 2026, above the Bank of England's 2% target. On 30 July, the Bank's Monetary Policy Committee voted to hold interest rates at 3.75% for the fifth time this year, with three of the nine committee members actually voting for a rate rise. The Bank's own projections now show inflation peaking at around 3.2% in the final quarter of 2026, a slight improvement on the sharper peak feared back in the spring, but still well above target. The Bank has separately warned that around 5.2 million UK households face higher mortgage costs by the end of 2028 as a result of the shock, up from 3.9 million expected before the conflict, though it describes the scale of those increases as likely to remain modest.
The Food and Drink Federation has warned that grocery costs could rise by as much as 10% across 2026, driven mainly by higher energy costs and fertiliser prices, both of which are pushed up by the same oil and gas dynamics affecting your fuel bill. Analysts studying past shocks note that once food prices rise, they tend to come down only slowly, so this is one area where the effects of the conflict may be felt for some time even if the situation in the Gulf stabilises.
The cumulative effect: higher energy bills, elevated petrol prices, above-target inflation, and rising grocery costs all compete with the holiday budget, even where the flight itself hasn't got materially more expensive. This is a genuinely different story to the one we told back in the spring, when the flight price itself looked like the main risk. Five months on, it's the wider cost of living, not the ticket, doing most of the damage to household budgets.
This is the question every undecided holidaymaker is asking, and the honest answer has shifted since our last update.
For European short-haul holidays, Spain, Greece, Portugal, Italy, Turkey, the fare-driven case for booking immediately is weaker than it looked in the spring, since easyJet and Ryanair have both chosen to hold fares rather than raise them. That said, booking now still gets you a fixed price and strong legal protection, at no real cost, so there's little reason to delay just for the sake of it.
For long-haul holidays via Gulf routes, the picture hasn't improved in the way it has for short-haul. Fares and disruption both remain elevated, and several major carriers have suspensions running into October. Waiting for more clarity on your specific airline's schedule remains a reasonable call here.
Either way, use flexible fares where available, and make sure you have package holiday protection or comprehensive travel insurance in place before you commit.
Five months into the Iran conflict, the honest picture is more reassuring on flights than it is on the wider cost of living. European short-haul fares, the ones that matter to the vast majority of UK holidaymakers, have held up far better than airlines themselves predicted back in the spring, because easyJet and Ryanair chose to compete on price rather than pass rising fuel costs straight through. Long-haul travel via Gulf hubs remains the exception, with real cost and disruption that's likely to persist into the autumn.
Where the squeeze is real is everywhere else: a 13% jump in energy bills this month, inflation running above target, interest rates held at a level that keeps mortgage costs elevated, and grocery prices still climbing. None of that is about your flight, but all of it competes with your holiday budget.
The best thing you can do for your holiday budget right now is make decisions rather than postpone them. Book the holiday you want, lock in today's price, make sure you have the right cover in place, and look forward to going.
