Airlines are warning of potential disruptions this summer due to escalating conflicts in the Middle East and rising jet fuel prices. Ryanair's chief executive, Michael O'Leary, indicated that the ongoing tension over the Strait of Hormuz could lead to jet fuel shortages, which may result in flight cancellations affecting 5-10% of scheduled flights.
He explained that the extent of cancellations would depend on fuel availability at different airports and that airlines will attempt to minimize inconvenience by grounding only a few aircraft. Most flights, however, are expected to operate as usual despite these challenges.
Impact on summer travel and fuel costs
O'Leary advised travelers to book their summer flights early to avoid rising fares, which have surged due to disrupted oil supply and refinery operations. Major airports, including Chicago, Houston, Los Angeles, and New York, are experiencing jet fuel prices nearly double prewar levels.
“It’s going to be difficult. It’s going to be challenging,” said O'Leary, highlighting the uncertainty surrounding summer flights.
He cautioned that passengers affected by cancellations might not be eligible for refunds, citing exceptional circumstances. Nonetheless, he reassured European travelers that airlines like Ryanair are prepared to re-accommodate affected passengers and that within Europe, the likelihood of flight operation remains high, despite potential disruptions from air traffic control strikes.
In summary, O’Leary estimated the risk of cancellations in June and July to be around 5-10%, emphasizing that most flights will still serve travelers. He urged early booking to prevent paying higher prices amidst ongoing geopolitical tensions and fuel shortages.
