Spirit Airlines Won't Be The Last: IATA Chief Warns More Carriers Could Fail As Iran War Drives Up Fuel Costs

IATA's Director General Willie Walsh warned that rising jet fuel prices driven by the Iran war could trigger more airline bankruptcies and consolidation, particularly among budget carriers lacking premium revenue streams. Spirit Airlines' recent collapse exemplifies the trend, though Walsh noted Ryanair's strong performance proves the budget model remains viable. Major U.S. carriers are squeezing out low-cost rivals, while manufacturing delivery backlogs and slower sustainable aviation fuel development add further pressure to the industry.
