It comes just a fortnight after the Irish budget carrier issued a profit warning, cutting its full-year forecast for the second time in the past three months.
The airline on Monday reported average fares down 6% in the three months to December 31, 2018, to less than €30 (£26) due to “excess winter capacity in Europe”.
Q3 revenue, though, grew 9% to €1.53 billion (£1.34 billion), which Ryanair said was on account of strong ancillary revenue up 26% to €557 million (£487 million), albeit offset by “higher fuel, staff and EU261 costs”.
