There has been a breakdown in talks between Aer Lingus management and striking pilots represented by the Irish Air Line Pilots' Association.
The dispute has led to the cancellation of hundreds of Aer Lingus flights including the EI 105 and EI 104 to and out of JFK in New York.
According to RTE, in leaving the talks IALPA President Captain Mark Tighe said the IALPA executive would more than likely meet today (Thursday) or by lunchtime tomorrow to reach a formal decision about what the union goes from here.
He said the options on the table could include everything up to a complete withdrawal of service.
Tighe said that IALPA officially moved from the figure of 23.8% that it was seeking for a pay rise.
"The company has not moved from its statement that anything more than 12.25% would have to be funded by pilots' own payments through work practice changes," he said.
On his way out of the talks, and again according to RTE, chief Corporate Affairs Officer at Aer Lingus, Donal Moriarty, said the company had tried to engage constructively with the union.
He said they tried to discuss issues that would resolve the dispute, in particular productivity, flexibility and the modernisation of collective agreements.
He said these were essential to meeting a pay deal with IALPA that is over and above the 12.25% that had been agreed with other groups in Aer Lingus.
"Unfortunately, IALPA was unable to enter into discussions on those items, in fact it informed it had no mandate to do so," he said.
