EasyJet has cancelled 233 flights ahead of the French strike on Thursday, December 5. The carrier is the second most important airline in France in terms of passenger numbers, and the cancelled flights are both internal and pan-European.

The airline also warned of significant delays as a result of air traffic controllers joining the protest against pension reform, and urged passengers to check with the airline before travelling to the airport. Its pilots had not notified the airline that they would join the action, easyJet said.

Ryanair said it would also cancel some flights, but was unable to give French news agency AFP any numbers. Meanwhile Air France said on Tuesday that it would cancel 30 percent of its internal flights and 15 percent of its medium-haul flights. No long-haul flights would be affected, the airline said.
