Talks aimed at resolving the Ryanair dispute are continuing this evening.
It is the third day of negotiations to try and prevent more strikes.
Representatives from the Forsa union and Ryanair management have been locked in talks since Monday to try and resolve the ongoing dispute.
The row over base transfers, annual leave and promotions has led to five days of industrial action by some Irish-based pilots.
Negotiations started again this morning led by mediator Kieran Mulvey - and they're expected to last until the end of the day.
He has asked both sides not to make a public comment while the deadlock continues.
If the two sides cannot reach a breakthrough by tonight, it could mean more strikes - and more disruption for passengers.
The third and final day of fresh talks aimed at resolving the dispute at Ryanair will take place this morning.
Both sides will aim to reach a deal at the discussions at Dublin Airport over base transfers and promotions to prevent more strikes.
It has already led to five days of industrial action and the cancellation of around 100 flights.
Mediator Kieran Mulvey will chair the negotiations between the airline and the Irish Airline Pilots Association.
