Aer Lingus has moved part of its customer service operation to the Philippines.
The development follows a decision by the airline in August not to renew a contract with Kerry-based Fexco, which had been dealing with a portion of queries from customers in Ireland and Europe.
However, the Irish carrier says it will move many of the functions back to another leading European customer service provider early next year.
After that, the call centre in the Philippines will revert to providing web chat and out-of-hours customer support, with the new European based provider managing the majority of customer queries from Ireland and Europe.
Fexco will continue to provide services in the area of group bookings.
A spokesperson for the Killorglin headquartered firm said it would not comment on its agreements with commercial partners or on the possible implications for employees who had been working on the contract.
The airline says the changes were prompted by a continuous process of review that it carries out on its third party contracts, as part of its value carrier model.
Aer Lingus said it continues to operate its US-based call centre and its specialist team based in Dublin.
"Aer Lingus remains committed to providing our guests across the globe with the very best level of service and care at all stages of their journey, offering 24/7 assistance to best meet the needs of our guests," it said in a statement to RTE News.
