European airlines should use US-made jet fuel to ease potential shortages caused by the US-Israel war with Iran, two major international airline bodies have suggested.

The International Air Transport Association (IATA) has suggested that wider international acceptance of US-grade jet fuel could help to head off any supply problems.

Meanwhile, the European Aviation Safety Agency (EASA) has drawn up safety guidance, setting out how US supplies could be introduced into the European market, as well as information on the risks involved.

The price of jet fuel most European airlines currently use has jumped by half since the start of the war.

In a blog post, IATA's director of flight and technical operations, Stuart Fox warned that if the conflict in the Middle East continues "it won't be long before we see fuel shortages in some parts of the world".
