European authorities moved swiftly this week to address mounting pressure on the continent's aviation fuel supply by authorizing the use of American Jet A fuel under controlled conditions.
The European Union Aviation Safety Agency issued Safety Information Bulletin 2026-04 on May 8, outlining how airlines, airports and fuel handlers can safely introduce Jet A into systems primarily designed for Jet A-1. The bulletin emphasizes that while the fuel grades are compatible, differences in specifications particularly the higher maximum freezing point of Jet A necessitate careful management to prevent operational issues on long-haul or high-altitude flights.
This development comes against the backdrop of the ongoing closure of the Strait of Hormuz, a critical chokepoint for oil and energy shipments. The blockage, linked to the conflict involving Iran, has sharply reduced maritime exports from the Middle East, driving up costs and raising fears of shortages during Europe's busy summer travel period. European producers supply 60 to 70 percent of the region's jet fuel needs, with a significant portion of imports historically routed through the strait.
According to multiple reports, the European Commission published clarifying guidance confirming there are no legal obstacles to importing and burning Jet A, provided users of shared fuel systems agree and risks are properly controlled. EASA explicitly stated that introducing the fuel type would not create safety concerns when appropriate procedures for air operators, ground handling and communications are reviewed and implemented.
Jet A is already standard in North America and has been used on transatlantic return flights to Europe. Its slightly lower cold-weather performance compared with Jet A-1 has historically limited broader adoption in the EU for technical reasons.
EU Transport Commissioner Apostolos Tzitzikostas reaffirmed that existing passenger rights legislation remains fully in force. Carriers facing higher fuel expenses cannot cite the situation as an extraordinary circumstance to avoid paying compensation for canceled flights, he said. Some airlines, including Lufthansa, have already reduced schedules in response to the economic pressures, with reports of thousands of flights cut in recent weeks.
The crisis has also sparked debate in European political circles over fuel allocation. Lawmakers from the Greens have called for temporary restrictions on non-essential private jet operations to preserve supplies for commercial and essential services, citing social equity concerns. Business aviation representatives counter that the sector consumes only a small fraction of total aviation fuel and warn against measures that could harm a vital industry segment.
While officials maintain that widespread travel disruptions are not yet occurring, the combination of elevated prices and supply uncertainty has increased ticket costs significantly on both short-haul and long-haul routes. Transatlantic operators in particular face added challenges. Increased U.S. exports of jet fuel to Europe have helped offset some losses, but overall supply remains constrained.
Industry groups such as Airlines for Europe had requested regulatory flexibility to tap into greater volumes of U.S. product. The coordinated response from the Commission and EASA appears to provide that pathway while maintaining rigorous safety standards.
Aviation stakeholders will now focus on updating fuel management protocols and supply chain agreements to incorporate the new fuel grade smoothly. The situation remains fluid as diplomatic efforts continue regarding the strait, with any reopening likely to ease pressure on both prices and availability across the region.
