The Irish Air Line Pilots' Association has voted to recommend acceptance of a Labour Court recommendation around pay at Aer Lingus.
The pilots union says it will "move immediately to suspend ongoing work-to-rule action, in place since 26th June, pending the outcome of a ballot".
IALPA met and passed a motion late on Wednesday to recommend acceptance of the Labour Court's recommendation following further clarification from the airline.
The union says it will hold a series of engagements with members before a ballot on the terms of the Labour Court recommendation "in the coming week".
IALPA President Mark Tighe described the pay increase provided for in the recommendation as "a significant win for pilots".
Aer Lingus says it welcomes the recommendation of acceptance of the Labour Court recommendation and its decision to discontinue the industrial action.
"We look forward to IALPA completing the balloting process as soon as possible," it adds.
The Labour Court is recommending a 17.75% pay increase which has already been accepted by Aer Lingus.
The non-binding recommendation covers a four-year period from January 2023 to the end of December 2026.
It also recommends a 10% increase to overnight allowances and a further 5% from October next year.
'Really positive development'
Taoiseach Simon Harris has welcomed the breakthrough in the pilots' dispute at Aer Lingus.
"I very much welcome the decesion by IALPA to suspend their industrial action and to recommend acceptance of the Labour Court proposal," he said.
"This is a really positive development for many people who've been worried about the impact that this will have on their summer holiday - or indeed many businesses in Ireland who've been worried about the impact it's going to have on the tourism sector.
"I hope that the ballot will take place quickly and that this matter can be resolved once and for all," he added.
Over the course of the dispute hundreds of flights have been cancelled.
