A number of flights between Dublin Airport and France on Thursday have been cancelled due to an air traffic control strike in France.
There may also be delays to flights required to use French airspace, according to a statement from Aer Lingus.
Two Ryanair return flights to Nantes and Carcassonne in France have been cancelled so far on Thursday due to the strike, and the airline is warning of further possible disruption to other flights in and out of Ireland over the course of the day.
Passengers intending to fly either to or from France are advised to check with their airline.
Ryanair has so far had to cancel nearly 120 flights across Europe due to the dispute, which affects flights using French airspace as well as flights to and from France itself.
Aer Lingus has so far reported no disruption to any of its scheduled departures or arrivals, but has encouraged customers to check the status of their flight before departure.
Thursday’s action is the latest in a series by French air traffic controllers who are calling for better pay and conditions.
