Passengers using Dublin airport have been warned that at least ten flights will be disrupted overnight due to ongoing action by air traffic controllers.
Air traffic controllers are refusing to work overtime in a dispute with the Irish Aviation Authority (IAA) over "chronic staff shortages". Airlines affected include Aer Lingus, Aer Arann and Ryanair.
The dispute has also affected flights at Shannon and Cork airports.
The Irish Aviation Authority said eight inbound and two outbound flights at Dublin airport will be affected between 11.30pm tonight and 6.30am tomorrow. It said passengers should contact their airline for further information.
The IAA said in a statement it "regrets the inconvenience to the travelling public and to airlines".
The air traffic controllers are seeking enhanced overtime and changes to their roster.
Further talks are scheduled to take place at the Labour Relations Commission next Tuesday between the IAA and the Impact union, which represents the air traffic controllers.
