Unions for Aer Lingus cabin crew have not ruled out further strike action depending on the outcome of talks scheduled for later this week.
A 24-hour stoppage hit over 200 flights on Friday and around 800 staff staged a protest at Dublin airport.
Staff are unhappy with changes to their rosters which they claim are having a detrimental effect on cabin crew.
Aer Lingus issued a statement calling the strike "unwarranted and unnecessary".
The disruption was worsened as hundreds of strike-bound passengers on an Aer Lingus flight to Boston were refused pre-flight immigration clearance in Dublin.
According to the Irish Times, the flight had been laid on specially to accommodate passengers who had intended to travel to the US but were forced to change their plans because of the one-day strike.
Passengers arrived at Dublin hours ahead of the Boston flight expecting to clear immigration, but had to join the normal immigration queues.
Aer Lingus admitted it had failed to communicate with passengers that the flight was not pre-cleared.
