Why does Willie Walsh say air fares will rise this summer, and what is the main cause?

Willie Walsh says air fares in Europe will rise this summer because of the high cost of jet fuel, which has surged due to the US-Israeli war on Iran and Iran’s effective closure of the Strait of Hormuz—a critical shipping route. He states that while airlines cannot absorb these extra costs indefinitely, widespread flight cancellations can be avoided and there is no need to panic—yet shortages remain a real risk during the peak summer period when fuel demand normally increases by 25% compared to March.

What measures are European authorities taking to address potential jet fuel shortages?

European authorities are pursuing several measures: the EU confirmed there is no regulatory barrier to using US-grade jet fuel if introduced carefully; EU Energy Commissioner Dan Jørgensen acknowledged no immediate threat but warned of longer-term shortages; the UK government has imported more fuel from the US, increased domestic refinery output, and introduced a temporary rule allowing airlines to consolidate passengers from multiple flights onto fewer planes to conserve fuel.
