Aviation fuel disruption expected in May - O'Leary
The aviation industry is bracing for a potential supply shock as Ryanair CEO Michael O'Leary warns that significant jet fuel shortages could hit the European market as early as May 2026. This warning comes amidst escalating geopolitical tensions in the Middle East, specifically the ongoing conflict involving Iran and the effective blockade of the Strait of Hormuz, a critical maritime artery for global oil and refined product shipments. While airlines have managed to maintain operations through the early months of the year, the depletion of regional reserves and the continued disruption of tanker traffic are creating a countdown toward a period of high volatility for travelers and carriers alike.
According to Ryanair CEO Michael O'Leary, aviation fuel disruption is expected in May 2026 if the conflict in Iran persists and the Strait of Hormuz remains closed. O'Leary indicates that while current supplies are stable through April, approximately 10% to 25% of the airline's fuel supply could be at risk during May and June. This supply shock is driven by the fact that over 20% of the world's oil passes through the Strait, and European refineries are heavily dependent on these Gulf imports for jet fuel production.
Geopolitical Tensions and the Strait of Hormuz
The primary driver behind the looming fuel crisis is the strategic importance of the Strait of Hormuz. In the wake of the Iran war, shipping traffic through this narrow waterway has seen a dramatic collapse. For the aviation sector, this is a catastrophic development because refined products, particularly Jet A-1 fuel, are not easily substituted at scale. The blockade prevents tankers from reaching European ports, forcing a reliance on dwindling local reserves that were only intended to cover about thirty days of normal demand.
Michael O'Leary's assessment aligns with broader industry concerns voiced by the International Air Transport Association (IATA). The association has noted that while crude oil prices are a major factor, the physical availability of refined jet fuel is the more immediate threat. Unlike gasoline or diesel, which have more diversified refining bases, a significant portion of Europe's high-grade aviation fuel originates from or relies on crude passing through the Persian Gulf.
Ryanair's Hedging Strategy and Exposure
Despite the dire warnings, O'Leary has pointed out that Ryanair is in a stronger position than many of its competitors. The airline has successfully hedged approximately 80% of its fuel requirements through March 2027 at a rate of roughly $67 per barrel. This financial maneuver protects the company from the full weight of skyrocketing market prices, which have seen jet fuel surge toward $200 a barrel in some regions.
However, hedging against price is not the same as hedging against a physical absence of fuel. The remaining 20% of Ryanair's needs is currently exposed to spot market prices, which have nearly doubled in recent weeks. More importantly, if the fuel literally does not arrive at the airports, no amount of financial hedging can keep the planes in the air. This is why O'Leary has emphasized that the "supply risk" is now a more pressing concern than the "price risk."
Impact on European Aviation and Flight Cancellations
The potential for flight cancellations is a reality that passengers must face as the May deadline approaches. If fuel companies cannot guarantee delivery into June and July, airlines across the continent will be forced to "thin out" their schedules. This means fewer daily frequencies on popular routes and the potential cancellation of less profitable regional flights to preserve fuel for core operations.
The UK is cited as being particularly vulnerable. Because the UK market relies on Kuwait for approximately 25% of its jet fuel supply, any prolonged closure of the shipping lanes in the Middle East hits British airports harder than their counterparts in Southern Europe. Travelers planning summer holidays are being advised to monitor their flight statuses closely, as the industry enters an era where geopolitical stability is no longer a given.
The Role of EU and Government Intervention
Governments are not sitting idly by as the crisis unfolds. Ireland's Transport Minister, Darragh O'Brien, has confirmed that the issue of aviation fuel resilience is now a top priority at the EU Energy Council. Discussions are underway regarding the activation of strategic reserves and the potential for collective purchasing to stabilize the market. There is also pressure on the European Commission to unveil a package of energy measures that would specifically address the vulnerabilities in the aviation supply chain.
| Risk Factor | Estimated Impact (May-June 2026) |
|---|---|
| Supply Shortfall | 10% to 25% of total volume at risk |
| Price Volatility | Jet fuel prices potentially exceeding $195/barrel |
| Operational Change | Potential for widespread schedule reductions |
| Regional Vulnerability | UK and Northern Europe most exposed to Gulf disruptions |
Sustainable Aviation Fuel (SAF) as a Long-term Solution
While the current crisis is a result of immediate geopolitical conflict, it has highlighted the dangerous dependency of the aviation sector on a single, geographically concentrated fuel source. Industry experts argue that this should serve as a catalyst for accelerating the transition to Sustainable Aviation Fuel (SAF). SAF can be produced locally from waste oils, agricultural residues, or even captured carbon and green hydrogen.
However, SAF production is currently in its infancy and cannot meet more than a tiny fraction of global demand. The current fuel shock demonstrates that energy security is now a matter of national security for aviation-dependent nations like Ireland and the UK. Moving forward, the "News Trending Update" for the industry will likely focus on how quickly carriers can diversify their fuel types to avoid being held hostage by the closing of a single maritime strait.
Traveler Advice and Market Sentiment
Despite the warnings from O'Leary, travel agents suggest that there hasn't been a massive wave of surcharges—yet. Airlines are currently focused on filling seats and maintaining consumer confidence for the Easter and early summer periods. However, the sentiment is shifting. If the war in Iran does not find a diplomatic resolution by mid-April, the "risk to supply" that O'Leary speaks of will become a physical reality at airport fuel depots.
Passengers are encouraged to book early and consider travel insurance that covers "travel disruption" specifically related to fuel shortages, though such clauses can be difficult to find. The industry's fate rests on the reopening of the Strait of Hormuz. If tankers resume their normal routes by late April, the crisis may pass as a mere "warning shot." If not, May 2026 could mark the beginning of one of the most challenging summers in the history of commercial flight.
Infrastructure and the Hydrogen Alternative
In the background of the liquid fuel crisis, the discussion around hydrogen-powered aviation is gaining momentum. While large-scale commercial hydrogen flight is not expected until the 2030s, the current supply chain vulnerabilities of fossil-based jet fuel are making the massive capital investment required for hydrogen infrastructure look more attractive to policymakers. Developing a domestic green hydrogen supply chain would provide a level of energy sovereignty that the current petroleum-based system cannot offer.
The "Hydrogen Supply Chain" involves production through electrolysis, storage in cryogenic tanks, and distribution via specialized pipelines or trucks. While complex, it removes the "Strait of Hormuz" variable from the equation. For an airline like Ryanair, which operates a massive fleet across a concentrated geographic area, the long-term move away from imported Gulf oil is becoming a strategic necessity rather than just an environmental goal.
Conclusion
The warning from Michael O'Leary is clear: the aviation industry is operating on a razor-thin margin of error regarding its fuel supply. The expected disruption in May is not a certainty, but a "reasonable risk" that hinges entirely on the de-escalation of conflict in the Middle East. As refined fuel reserves in Europe reach critical levels, the next few weeks will determine whether the summer of 2026 is defined by the freedom of flight or the frustration of grounded fleets. Stakeholders from government ministers to holidaymakers must now wait and see if the vital shipping lanes of the Gulf will reopen in time to prevent a continent-wide aviation standstill.
Frequently Asked Questions
Q1: Why does Michael O'Leary expect fuel disruption in May?
A1: The expectation is based on the continued closure of the Strait of Hormuz due to the Iran war, which prevents jet fuel and crude oil from reaching European refineries, leading to a depletion of local stocks by early May.
Q2: Will flight prices increase because of this?
A2: While Ryanair has hedged 80% of its fuel, the remaining 20% is subject to high market prices. Furthermore, if supply is limited, the resulting reduction in flight capacity usually leads to higher fares across all airlines.
Q3: Which countries are most at risk?
A3: The UK is considered highly vulnerable because it relies on Kuwait for about 25% of its jet fuel supply. Other Northern European countries with low domestic refining capacity are also at higher risk.
Q4: What happens if I have a flight booked in May or June?
A4: At this stage, flights are scheduled to proceed. However, O'Leary has warned that if supply risks reach 10-25%, airlines may have to start cancelling flights to manage limited fuel availability.
Q5: Can airlines use other types of fuel?
A5: Commercial jets require specific Jet A-1 fuel. While Sustainable Aviation Fuel (SAF) is an alternative, it is currently produced in quantities far too small to replace traditional jet fuel in the event of a major supply disruption.
