Michael O’Leary, the CEO of Ryanair, has issued a warning regarding the potential impact of the ongoing conflict in Iran on air travel. If the Strait of Hormuz remains closed for an extended period, airlines could face jet fuel shortages, leading to a 5-10% cancellation of scheduled flights for May, June, and July. O’Leary emphasized that airlines might not have the ability to choose which flights to cancel, as it will depend on the available jet fuel at each airport. He strongly advises travelers planning summer trips to book their tickets early to avoid significantly higher fares. Jet fuel prices have surged to an average of $4.88 per gallon in major U.S. cities, nearly double prewar levels. Furthermore, passengers affected by cancellations may not be eligible for refunds, as airlines can cite extraordinary circumstances. However, O’Leary assured that Ryanair would work to re-accommodate passengers within Europe, despite potential disruptions from factors such as French air traffic controller strikes.
