Ryanair today announced it was selling one million seats at £9.99 in an effort to combat the effects of the terrorist attacks in the US.
The company pledged it would not make any staff redundant and would take delivery of eight new aircraft - as well as opening new routes and adding flights to existing routes.
The offer of one million seats at £9.99 one way would be sold for travel during September, October and November, the company said and are only available through its website Ryanair.com.
The Ryanair announcement has come as travel operators Airtours warned job losses could not be ruled out in following the terrorist attacks in the US.
Chief executive Mr Tim Byrne said Airtours, which employs 29,000 people worldwide, was not planning any immediate cuts but said: "I don't think you can rule out job losses - we will do what we have to in these difficult circumstances to tighten our belt".
Aer Lingus announced a cost-cutting package last week that may mean the loss of up to 1,700 jobs.
British Airways has already announced 5,200 job cuts and grounded 20 aircraft because of a drop in demand. On Friday, its share price plunged to 114p - on the day before the attacks it closed at 264p.
The stock rallied, however, towards the end of the day after the Treasury said it had reached an agreement with insurers over third-party cover.
Virgin Atlantic cut 1,200 jobs last week and cut services in the US and Canada ahead of expected reductions in demand for flights.
