European airline industry groups are urging carriers to consider using jet fuel produced in the United States to ease soaring prices and potential shortages triggered by the war involving the United States, Israel and Iran. The International Air Transport Association said broader acceptance of United States grade Jet A fuel in Europe could help stabilize supplies as deliveries of Jet A-1 from the Gulf region decline.

Jet A-1, the standard fuel for most international flights, has become significantly more expensive, with prices rising by about half since the conflict began. Europe relies heavily on imports from the Gulf, and reduced shipments have tightened supply. While additional fuel is being shipped from the United States, many refineries there primarily produce Jet A rather than Jet A-1.

The European Aviation Safety Agency has issued guidance on how Jet A could be safely introduced into the European market. Although Jet A has a slightly higher freezing point than Jet A-1, it is widely used in North America, including in very cold regions, with the help of additives and careful flight planning. Regulators cautioned that any transition must be carefully managed to avoid operational risks, particularly if different fuel grades are inconsistently available across airports.
