Aer Lingus passengers on most flights from Dublin Airport faced delays of up to two hours today following a stoppage by clerical staff this morning.
At 6am, 100 clerical staff were instructed by their SIPTU shop stewards to leave their posts and attend a one-hour meeting.
It is understood the dispute centres on staff being asked to work both on check-in and boarding flights. Aer Lingus said the stoppage was held without notice or authorisation by the airline.
Transatantic schedules were not affected, except this evening's 5pm flight to New York. All other Aer Lingus flights were delayed for between one and a half and two hours.
The union said there will not be any further disruption this weekend pending a meeting with management on Monday.
