Aer Lingus cabin crew at Shannon Airport have voted to accept proposals drawn up at the Labour Relations Commission (LRC) to resolve a dispute over staffing new transatlantic services.
The trade union IMPACT says crews have voted 83% to in favour of new proposals.
It is understood transatlantic flights will still be staffed by Aer Lingus crew rather than being out-sourced.
The dispute relates to staffing arrangements for new Aer Lingus transatlantic services that are set to begin in 2014 and will be using a smaller Boeing 757 aircraft.
Management at the airline had previously said it would have to outsource cabin crew on the new routes from Shannon, after IMPACT refused to operate the flights with fewer crew members.
Aer Lingus staff had earlier voted for industrial action and that remains on the table as other issues have not been resolved.
But Niall Shanahan from IMPACT says the LRC deal should mean the imminent threat to Shannon is over.
