Airlines are monitoring fuel supply risks as tensions affecting oil routes raise concerns about possible disruption later this spring. Ryanair’s chief executive Michael O’Leary said that jet fuel availability could be affected in May if the conflict linked to Iran continues to limit tanker traffic through the Strait of Hormuz. The shipping route is a key global energy corridor, and any continued restrictions may influence fuel costs and supply stability.

O’Leary stated that Ryanair has secured most of its fuel needs in advance, though the remaining share is currently being purchased at significantly higher prices. While the airline expects to operate its planned schedule, uncertainty remains about fuel availability across Europe if market conditions remain unstable. Industry observers note that fuel access, not only price increases, could influence airline operations during the early summer travel period.

“Fuel suppliers are constantly looking at the market. We don’t expect any disruption until early May, but if the war continues, we do run the risk of supply disruptions in Europe in May and June, and we hope the war will finish sooner than that and the risk to supply will be eliminated."
Michael O’Leary, CEO of Ryanair

Several airlines have warned that rising fuel costs may lead to higher ticket prices in the coming months as older fuel contracts expire and new supplies are purchased at current market rates. Some carriers have already reduced flight frequencies to limit expenses, affecting thousands of passengers as airlines respond to changing conditions in the global energy market.

Summer flight schedules are planned months ahead, with fuel costs playing a major role in these decisions. Instead of cutting destinations, airlines may reduce the number of weekly departures or adjust aircraft size on certain routes. Connections between major cities and holiday destinations generally remain, even as airlines face higher fuel costs.

As a result, some routes may offer fewer departure times, especially during the busiest summer weeks. Certain flights may disappear from booking systems, and seats on remaining departures can be booked faster than usual on popular holiday routes. Looking at a few different travel dates and checking flight times again closer to departure gives a better idea of what options are still available if airlines change schedules.
