Aer Lingus management and IALPA are waiting for a Labour Court recommendation to resolve their pay dispute.
Industrial action by pilots has led to the cancellation of 548 flights up until July 14.
The decision from the Labour Court will not be binding and will be put to a ballot of IALPA members.
IALPA is seeking a pay rise of up to 24pc to account for inflation, while Aer Lingus is looking for productivity and flexibility in return for any pay increases beyond 12.25pc.
