Ryanair and easyJet have warned of possible flight disruptions starting May 1, 2024, due to anticipated jet fuel shortages resulting from the ongoing conflict in the Middle East, particularly around the Strait of Hormuz. The situation has escalated as US Vice President JD Vance recently concluded 21 hours of negotiations in Islamabad with Iran without reaching a deal regarding a ceasefire. A letter to the Financial Times highlighted the airport industry's growing concerns about jet fuel availability, stating that without significant improvements in the situation within the next three weeks, a systemic shortage could become a reality for the European Union. Ryanair's CEO, Michael O'Leary, indicated that if the conflict persists, there could be a 10% to 25% risk to fuel supplies in May and June. Meanwhile, EasyJet's CEO, Kenton Jarvis, noted that while pricing is volatile, the airline is well positioned in terms of fuel supply management.
