Jet fuel prices are rising again as industry leaders warn it will take months to restore Mideast flows through the Strait of Hormuz once it reopens, with disruptions likely to be felt well into next year. The outgoing head of the International Air Transport Association, Willie Walsh, has warned that higher fuel bills will push up airfares in Europe this summer even if widespread flight cancellations caused by fuel shortages can be avoided. Walsh’s former company, IAG, said this week that higher fuel prices would add €2 billion ($2.3 billion) to the airline group’s costs this year. Only one jet tanker has managed to pass through the strait since war broke out, keeping roughly 375,000 barrels per day of jet from global markets.
