European aviation faces critical fuel crisis within weeks

Europe faces a critical aviation fuel shortage over the next three weeks unless the Strait of Hormuz reopens, according to a urgent alert from the airport industry across Europe. The Airports Council International (ACI) Europe has warned European commissioners that systemic jet fuel shortages will become reality if the Persian Gulf passage continues to be blocked, as the region delivers roughly 50% of Europe’s fuel imports. The alert arrives as airlines worldwide have already started reducing flights and boosting fares amid fuel supply concerns, whilst key fuel price indicators have soared to an unprecedented level of $1,838 per tonne—more than double pre-war levels. Smaller airports across Europe are viewed as especially at risk to service interruption during the approaching summer tourism season.

The three-week countdown

In a message to EU energy and tourism commissioners dated 9 April, ACI Europe’s chief executive Olivier Jankovec presented a detailed schedule for possible crisis. If the Strait of Hormuz does not resume significant and stable passage within 21 days, the continent will encounter widespread aviation fuel deficits that will significantly impact aviation services and flight links across the European Union. The warning emphasises the vulnerable standing of Europe’s aviation sector, which depends substantially on Gulf supplies and has already seen fuel costs increase twofold since the conflict began.

The timing could barely be worse. Summer constitutes the busiest period for European tourism and aviation, when airports typically operate at maximum capacity and passenger demand reaches its highest point. Olivier Jankovec stressed that “relying purely on market forces and adaptation is not viable,” calling instead for direct EU intervention through collective fuel purchasing and temporary relaxation of import restrictions. He emphasised that smaller aviation hubs, already grappling with viability issues, could face existential threats if shortages materialise during the critical summer period.

• Strait of Hormuz closure jeopardises 50 per cent of UK and European jet fuel supplies
• Airlines worldwide already reducing flights and increasing passenger charges preemptively
• Benchmark jet fuel prices reached peak $1,838 per tonne, up from $831
• Summer tourism season approaching, heightening urgency of fuel supply crisis

Regional airports carry the weight

Europe’s compact airports face heightened vulnerability from the impending fuel crisis, with facilities handling fewer than one million passengers annually already maintaining unstable financial conditions. These regional centres, which serve crucial connectivity across the continent and support local economies, lack the purchasing power and fuel reserves of major aviation centres. Jankovec warned that the current crisis risks making these already precarious facilities even more vulnerable, potentially leading to closures that would severely impact communities relying on air connectivity and the jobs that aviation supports.

The financial stakes go well past individual airports. Aviation contributes €851 billion annually to economies across Europe and supports 14 million jobs throughout Europe. A systemic fuel shortage would ripple across supply networks, the tourism sector, and regional development. Smaller airports, especially those in outlying areas, would face the most severe impacts, as they do not have alternative facilities and revenue streams to withstand prolonged disruption. The crisis therefore jeopardises not only aviation operations but broader European cohesion and economic stability.

Exposure across Europe

Regional airports operate with minimal fuel stockpiles and limited financial resilience compared to major hubs. Many do not have established connections with fuel suppliers, instead turning to intermediaries and spot market buying. During periods of supply constraint, these regional operations would struggle to secure adequate fuel at any price, forcing flight cancellations and operational shutdowns. The consequent disruption would disproportionately impact outlying European areas, where aviation offers vital economic connections and access to wider markets and employment prospects.

Market forces and price increases

The aviation sector is facing extraordinary fuel cost pressures, with jet fuel costs across Europe reaching an record peak of $1,838 per tonne the previous week—more than doubling from $831 before the conflict began. This significant 121 per cent increase demonstrates the unstable supply conditions and has already led airlines worldwide to implement cost-cutting measures. A number of airlines have reduced flight frequencies and introduced passenger fees to offset mounting fuel expenses, essentially transferring expenses to travellers during a period when demand for air travel typically peaks.

Jankovec stressed that current price levels are improbable to stabilise rapidly, warning that conventional jet fuel costs will probably remain elevated in the medium to long term. This systemic shift in fuel economics jeopardises airline profitability and operational sustainability, particularly for smaller carriers and regional operators with constrained financial reserves. The crisis demonstrates the urgent need for alternative solutions, including increased investment in sustainable aviation fuel production and European Union intervention to stabilise pricing and prevent additional price rises that could fundamentally transform European aviation’s competitive landscape.

Calls for unified EU-wide action

Olivier Jankovec, director-general of ACI Europe, has issued an urgent call for decisive intervention from European Union leaders, contending that market forces alone cannot resolve the looming fuel shortage. In a letter addressed to EU officials for energy and travel, he emphasised that depending exclusively on adjustments and spot purchasing would prove insufficient to avert widespread supply gaps. Jankovec’s statement underscores a critical governance gap: the European Union presently has no comprehensive mechanisms for assessing and monitoring aviation fuel supply and distribution across EU countries, rendering the region vulnerable to fuel supply interruptions.

ACI Europe has introduced tangible measures to mitigate the crisis, seeking EU backing for collective fuel purchasing arrangements that would leverage the continent’s pooled bargaining power. The organisation has also pushed for short-term relief of import restrictions and regulations that presently limit jet fuel availability. These recommendations demonstrate a fundamental shift in thinking—away from market-only approaches towards planned, collaborative action. Such measures would permit regional airports and smaller airlines to obtain fuel supplies at steadier costs, stopping the chain-reaction cancellations that threaten Europe’s peak holiday period and wider economic stability.

• Implement across the EU joint procurement of jet fuel to strengthen bargaining power
• Temporarily lift import controls constraining fuel availability
• Establish comprehensive monitoring systems for jet fuel production across member states

Eco-friendly aircraft fuel opportunity

The current crisis presents an opportune moment to increase investment in sustainable aviation fuel production and render it cost-effective, Jankovec argues. Whilst traditional aviation fuel prices are projected to stay high long-term, SAF provides a long-term route to price certainty and environmental sustainability. Supporting SAF expansion through direct financial support, policy measures, and infrastructure investment could shield European aviation from future supply shocks whilst advancing climate commitments. This dual-benefit approach transforms an pressing challenge into a driver for structural change within the aviation sector.

Economic stakes for Europe

The possible fuel crisis arrives at a especially vulnerable period for European aviation, which already faces mounting pressure from elevated operating costs and changing consumer behaviour. Air travel provides an estimated €851 billion each year to European economies and sustains 14 million jobs throughout the continent. A systemic jet fuel shortage would ripple through this integrated ecosystem, disrupting not only airlines and airports but also the tourism, hospitality, and hospitality sectors that depend on steady passenger flows. The summer tourism season—typically the industry’s most profitable period—would be severely compromised, threatening revenue streams for communities reliant on seasonal travel.

Smaller airports and regional carriers encounter disproportionate vulnerability to this crisis. Facilities handling fewer than one million passengers annually already contend with economic sustainability without accounting for fuel supply disruptions, according to Jankovec. A extended deficit could render some uneconomical to operate, potentially fracturing Europe’s aviation network and exacerbating regional disparities. The economic consequences reach past the aviation sector itself; reduced connectivity threatens commercial investment, trade flows, and the community bonds that cross-border travel facilitates. For outlying and remote communities, closure of airports could trigger broader economic decline and accelerate emigration of residents.
