British tour operator First Choice Holidays, which employs 200 people in Ireland, is cutting 1,100 jobs - around 10% of its workforce - in the wake of the terrorist attacks on the US.
A statement from the Irish operations confirmed that all elements of its business were under review and that this might results in some job losses. It said the numbers were being assessed but it hoped to keep them to a minimum.
First Choice owns Falcon/JWT Holidays and First Choice Travel Shops in Ireland. It has 24 stores and one call centre.
The British company said the cuts would help it respond to the changes in the market, where it has dramatically scaled back its winter programme.
Capacity for the first half of winter 2001, November to January, in the UK and Ireland has been cut by 15% and more reductions to the programme may be made.
First Choice said summer 2002 had been less affected by recent events but that it had adopted a cautious approach and reduced capacity by a fifth.
Up until September 11, First Choice said that its performance had been in line with the market's expectations.
The immediate cost of the disruption caused by the attack on the US and the subsequent effects across the business would be around £10m sterling.
First Choice's transatlantic business represents 5% of its full-year programme and 3% of its winter programme.
Meanwhile, Internet travel agency eBookers is cutting 140 jobs or one fifth of its staff because it says the US attacks will have substantial short term impact on its sales.
EBookers employs between 70 and 80 staff in Dublin, and a company spokesman said the operation was likely to be affected, but it was unclear yet what the level of cuts would be.
Ebookers has a call centre operation here, and also runs an Irish version of its service, eBookers.ie. Ebookers employs 700 full time staff in 11 countries.
