Ryanair chief executive Michael O'Leary warned in July that a downward trend in airfares could exceed 10% in the quarter but has since told Reuters that the risk now "looks like it has disappeared".

"While fares were kind of softening during April, May and June, that has levelled out," he said.

Elsewhere, Ryanair announced it will slash 20% of its traffic at Berlin's Brandenburg airport, resulting in a loss of 750,000 seats, after the German government and airport refused to meet the Irish airline's demands, including reversing an aviation tax increase and lowering air traffic control charges.

Ryanair's Berlin-based aircraft will be cut to seven from nine as six routes will be trimmed.
