A strike by French air traffic controllers has led to the cancellation of hundreds of flights, leaving thousands of people stranded.
Widespread cancellations and disruptions have affected both inbound and outbound flights in France and other European flights passing through French airspace.
The strike has been organised by France's largest SNCTA union in a dispute over working conditions, including the plan to raise the retirement age for air traffic controllers from 57 to 59.
According to the BBC, the DGAC civil aviation authority had asked airlines to cut down their schedules for flights leaving and entering France on Wednesday by 40%.
Ryanair has cancelled approximately 250 flights from Birmingham, Luton, Leeds Bradford, Stansted, East Midlands and Dublin. EasyJet and British Airways have also cancelled flights.
The Civil Aviation Authority has asked passengers due to fly out in the next few days to check with their respective airline before going to the airport.
A statement released by Ryanair read:"It's grossly unfair that thousands of European travellers will once again have their travel plans disrupted by the selfish actions of a tiny number of French ATC workers. All affected customers have been contacted by email and text message and advised of their options."
