Asked about the impact of the war on demand to fly to and around eastern Europe, O'Leary told reporters: "I think you will not have a dramatic impact on bookings as long as the period of war doesn't escalate and spread elsewhere."

O'Leary said that industry short-haul capacity would be down around 10% this summer, driving higher fares, adding that Ryanair would not introduce fuel charges for the summer.
