The Strait of Hormuz crisis is rewriting the economics of air travel in real time — and if you’re a budget traveler, the math is no longer working in your favor.
Since the US-Israel military campaign against Iran triggered an effective closure of the Strait of Hormuz in late February 2026, global jet fuel prices have gone vertical. Jet fuel averaged $195 a barrel last week according to the International Air Transport Association — more than double the average from a year earlier. For legacy carriers with diversified revenue streams, fuel hedges, and business-class margins to absorb shocks, this is painful. For low-cost and ultra-low-cost carriers, it is potentially fatal.
The reason is structural. Budget airlines built their entire business model on a single premise: keep base fares below the psychological threshold, make margins on ancillary fees, and rely on low and predictable fuel costs to hold the floor. Spirit Airlines, for example, drafted its post-bankruptcy recovery plan in February 2026 modeling financial viability on a projected fuel cost of $2.24 per gallon. The geopolitical shock in the Strait of Hormuz obliterated that projection. There is no version of the budget airline playbook that accounts for fuel costs doubling in a matter of weeks.
The two names most exposed in the European budget market are Wizz Air and easyJet — and both are already showing the strain. Wizz Air’s CEO warned in March that the airline expected a 50 million euro hit to its 2026 net profit. That is a significant blow for a carrier whose entire competitive position depends on cost discipline. EasyJet, meanwhile, said it expects to post a pretax loss of £540 million to £560 million for the first half of the year — a figure that reflects how brutally fast the fuel shock has moved through low-margin balance sheets.
Publicly, both carriers are managing the messaging carefully. An easyJet spokesperson told CNBC that the airline would not add surcharges to any pre-booked flights or package holidays, or to any future bookings for this summer. easyJet also said it wasn’t currently experiencing fuel shortages — a reassurance that lands differently when the IEA is simultaneously warning that Europe may have only weeks of jet fuel reserves left. Wizz Air has not publicly committed to the same no-surcharge position.
Europe is the most exposed aviation market structurally. The Strait of Hormuz accounts for around 40% of Europe’s jet fuel imports, and no jet fuel has passed the strait since the war broke out, according to Argus Media’s head of European jet fuel pricing. Around 75 percent of Europe’s jet fuel imports come from the Middle East overall, which means the alternative supply pipeline — US exports, Nigerian cargoes — cannot come close to filling the gap at speed. Before the conflict, approximately 360,000 barrels of jet fuel moved through the Strait of Hormuz every day, representing about 20% of shipped global flows.
The airport-level effects are already visible on the ground. Airports in Bologna, Milan, Treviso, and Venice have placed restrictions on jet fuel, with refueling services for certain operators subject to limitations due to constrained supply from Air BP Italia. Experts warn the situation could become systemic within weeks, with potential for severe flight cuts in Europe starting as early as May and June.
Ryanair CEO Michael O’Leary predicted summer cancellations of 5 to 10 percent of flights if the strait remains closed, singling out the UK as particularly vulnerable due to its dependence on Kuwaiti fuel supply chains. Meanwhile, rules have been quietly changed so that if airlines do need to cancel flights due to the crisis, they will not forfeit their take-off and landing slots — a regulatory adjustment that essentially gives carriers a green light to consolidate and cut without long-term penalty.
Legacy carriers are better insulated. Lufthansa has hedged approximately 80% of its fuel requirements for 2026 at pre-crisis price levels, giving it a meaningful buffer that Wizz Air and easyJet simply do not have. Air France-KLM has moved to raise fares on new bookings. These carriers will survive the summer. Budget carriers are running the numbers every week.
For travelers who built summer plans around cheap Wizz Air fares to Budapest or an easyJet hop to Malaga, the message is straightforward: the floor that made those tickets affordable has cracked. Airlines with no hedge, no business class, and no cargo revenue have nowhere to hide when their primary cost doubles. They will either impose surcharges on new bookings, quietly cancel routes deemed no longer viable, or both.
The practical advice is to book with flexibility, read the force majeure clauses in your low-cost carrier’s terms and conditions, and consider whether a somewhat more expensive ticket on a legacy carrier now buys real protection against a cancelled flight in July. Even after the US and Iran announced a ceasefire on April 8, ship traffic through the Strait of Hormuz remained far below pre-war levels — meaning the structural fuel supply problem has not resolved, and neither has the threat to the budget aviation model that millions of European travelers depend on every summer.
