Fuel Squeeze Puts Ryanair and easyJet Summer Schedules at Risk

European low cost carriers are entering the peak booking season facing mounting risks from jet fuel shortages, as fresh warnings from airports and airline disclosures suggest that supply constraints could disrupt Ryanair and easyJet operations within weeks.

Middle East Conflict Triggers a New Jet Fuel Shock

Publicly available energy and aviation data indicate that the ongoing conflict involving Iran and the closure of the Strait of Hormuz since early March 2026 have removed a substantial share of global jet fuel exports from the market. Industry analysis suggests that Europe, which relies heavily on refined products shipped from the Gulf, is among the most exposed regions to this disruption.

Reports from market commentators show that attacks on refinery and export infrastructure in Saudi Arabia and Iran have further constrained supplies, pushing jet fuel prices in Northwest Europe to record levels. Pricing assessments cited by specialist energy outlets describe a doubling of European jet fuel prices within weeks, with costs now far above levels seen earlier this year.

The International Air Transport Association and other aviation bodies have highlighted that fuel typically accounts for close to 40 percent of an airline’s operating costs. With prices surging at the same time as physical supplies tighten, analysts argue that European carriers face a dual challenge of securing sufficient fuel and absorbing sharply higher costs as the busy summer season approaches.

Economic research on the broader impact of the 2026 Iran war notes that Europe is already dealing with a significant energy shock. The emerging jet fuel crunch is being described by sector observers as a new front in that crisis, with aviation now directly exposed to the same supply risks affecting other transport and industrial users.

Airports Warn of ‘Systemic’ Shortages From Late April

The pressure on the aviation system became more visible in early April, when airport operators in Europe raised the alarm about potential fuel shortages. According to coverage of a letter dated 9 April from ACI Europe, the association representing European airports, officials warned that systemic jet fuel shortages could begin affecting operations from late April if shipping through the Strait of Hormuz is not restored.

Reports on the contents of the letter state that ACI Europe highlighted the risk of an EU wide fuel crunch within roughly three weeks, with particular concern for large hub airports that depend on steady deliveries of imported jet fuel. Some Italian airports are already reported to have started emergency rationing measures, prioritising fuel for certain flights and encouraging airlines to tanker additional fuel from less affected locations.

Published coverage also indicates that ACI Europe is urging the European Commission to explore coordinated responses, including joint purchasing of fuel and requirements for European refineries to increase jet output. While such steps would take time to implement, the call underscores how quickly the situation has escalated from a pricing issue to one of physical availability.

Airport and industry briefings suggest that if the Strait of Hormuz remains largely closed through May, on the ground impacts could include tight refuelling windows, aircraft being forced to operate with shorter range payloads, and rising numbers of schedule adjustments as airlines reallocate scarce fuel to their most profitable routes.

Ryanair Flags Capacity Cuts if Supplies Fall Short

Ryanair, Europe’s largest budget airline by passenger numbers, has emerged as one of the most vocal carriers on the growing fuel risk. In recent televised comments summarised by European media outlets, the airline’s leadership warned that if the Middle East war and associated supply chain disruption continue, between 10 percent and 25 percent of its fuel supplies could be at risk during May and June.

Reports indicate that Ryanair has not yet cancelled flights specifically due to fuel supply and continues to operate its full schedule, supported by significant fuel hedging that locks in prices for a large share of its needs. However, multiple news summaries note that the airline has begun to consider contingency plans, including reducing frequencies or cancelling selected flights from June if deliveries to key airports become unreliable.

Regional coverage from Spain and Ireland suggests that Ryanair is particularly concerned about bases in southern Europe, where airports rely heavily on imported fuel arriving by sea. If deliveries are interrupted or rationing intensifies, the airline could be forced to trim capacity on popular summer routes linking northern Europe with Mediterranean destinations.

Analysts following Ryanair state that the carrier’s strong balance sheet and hedging strategy may help it withstand price spikes better than some rivals, but they also underline that no hedge can fully protect against a true physical shortage. If refuelling is not available at specific airports, even well financed airlines may have limited options beyond adjusting schedules.

easyJet Faces Tight Delivery Window and Cost Squeeze

UK based low cost carrier easyJet is also confronting the consequences of the fuel squeeze. Financial news services report that the airline recently warned investors it can only be certain of guaranteed fuel deliveries for the next few weeks, highlighting the short term nature of its supply contracts amid rapidly changing market conditions.

According to these reports, easyJet has been hit hard by the doubling of jet fuel prices linked to the Middle East conflict, contributing to a sharp drop in the market value of major global airlines. Commentators note that easyJet’s asset light model, which relies on leased aircraft and tight cost control across a dispersed European network, now faces significant headwinds as fuel bills jump and operational risks multiply.

Coverage from UK and European outlets underlines that easyJet has a large presence at airports across the EU and the UK, including major hubs such as London Gatwick, Milan and Vienna. Many of these airports feature in ACI Europe’s warnings about potential systemic shortages, suggesting that easyJet’s core network is directly exposed to any disruption.

Market analysts quoted in recent briefings argue that if fuel deliveries become constrained at multiple bases at once, easyJet may be forced to consolidate operations on a smaller set of routes and airports, prioritising flights with the strongest revenue potential. That could mean reduced frequencies or temporary suspensions on thinner leisure routes, particularly in late spring and early summer.

Passengers Face Higher Fares, Tighter Schedules and Uncertainty

For travellers, the emerging fuel crisis adds another layer of uncertainty to European air travel. Industry commentary suggests that airlines across the region are already pushing through fare increases to offset higher fuel costs, with additional surcharges and reduced promotional activity likely if prices remain elevated.

Travel advice published in consumer focused outlets indicates that passengers planning trips for May through August may see fewer ultra low fares and less choice on some routes served by Ryanair, easyJet and their competitors. Where schedules are trimmed to conserve fuel, popular leisure destinations could experience reduced capacity, potentially driving prices higher on remaining flights.

Regulatory frameworks in the UK and the EU require airlines to provide refunds or rebooking options if flights are cancelled, but passenger groups note that last minute changes can still cause significant disruption to holiday plans. As a result, some travel commentators are recommending that customers monitor airline communications closely and allow extra flexibility in their itineraries during the early summer period.

While there is still time for conditions to stabilise if energy flows through the Strait of Hormuz improve, publicly available assessments from airports, airlines and energy analysts indicate that European aviation is heading into an unusually fragile season. For Ryanair and easyJet, whose business models depend on dense, reliable schedules, the coming weeks will be critical in determining how deep the fuel related disruption ultimately runs.
