Europe faces potential jet fuel shortages if the Strait of Hormuz does not reopen in three weeks, according to ACI Europe. The Gulf supplies about 50% of Europe's aviation fuel, raising concerns as summer tourism approaches. Smaller airports are particularly at risk. ACI Europe's director-general, Olivier Jankovec, warned of severe disruptions and economic impacts if the situation does not improve. The price of jet fuel has surged, and ACI Europe is urging the EU to intervene and support sustainable aviation fuel production.
