Staff can use the low fares on any of Aer Lingus’ routes but must go stand-by.
A spokesperson said that the reduction was part of the airline’s policy of lowering all fares.
He added that the move meant that Aer Lingus was now a low-fare airline.
The spokesperson denied that staff were being used to fill seats.
Flights to the UK and Europe will now cost staff between euro 13 and euro 18, plus tax and charges of euro 20. Flights to the east coast of the U.S. will cost euro 29, plus euro 50 in taxes and charges. Flights to Los Angeles will cost euro 41, plus euro 50 in taxes and charges.
Chief executive Willie Walsh announced a major new U.S. promotion to stimulate the north Atlantic route this summer.
“In Aer Lingus we have not stood idly by as the crisis in Iraq developed,” Walsh said. “In the United States, for example, we have initiated a campaign to harness the entire industry in a major promotion to stimulate travel entitled Aer Lingus 1,000 Welcomes Program.”
