Continuing industrial action by French air traffic controllers over labour reforms has caused European airlines, including Ryanair and Aer Lingus, to cancel flights.
Ryanair flights between Dublin and Madrid, Carcassone, Biarritz, Rodez, Nice and Nantes are affected along with flights between Cork and Bordeaux.
Aer Lingus has cancelled flights between Dublin and Barcelona, Madrid, Marseille, Perpignan, Nice and Bordeaux.
Both airlines are warning of delays to flights which need to use French airspace.
