The boss of budget airline Ryanair has warned that flight delays and cancellations will continue "right throughout the summer" as airports suffer amid staff shortages.
Michael O'Leary, chief executive of Ryanair, said passengers should brace for a "less than satisfactory experience", with flight delays due to last across the peak season and some airlines cancelling between 5% and 10% of flights.
He told Sky News this was "deeply regrettable".
