Flights to and from France and those passing through French airspace face disruption by the latest round of strikes due to take place tomorrow (Thursday).
A general strike has been called for by French Unions in protest to changes to the country’s labour laws.
Unions which represent French air traffic controllers, the USAC-CGT and CGT, have announced that they will support the strikes which are expected to run from 6pm tonight until to 5am on Friday.
Ryanair announced flight cancellations due to the action.
Some British Airways flights may also have to be cancelled with others facing disruption.
EasyJet said it planned to run its flights from France during the dispute but warned of potential delays and disruption to public transport serving French airports.
BA said: “We are expecting further periods of industrial action by the main Air Traffic Control trade unions as part of a national strike in France on the evening of Wednesday 15 November and all day on Thursday 16 November.
“Yet again this will unfortunately bring another wave of unnecessary disruption for some customers travelling in Europe.”
BA added: “Unfortunately, if the threatened strikes go ahead, we will have to cancel some flights as a result of the strike action and other short haul flights may also experience some disruption, given how many flights would normally use French airspace each day.
“We will be using larger aircraft, where possible, to help affected customers and are doing all we can to reduce the levels of disruption.”
Ryanair said: “We regret to advise customers that due to an air traffic control strike in France on 16th November, we have been forced to cancel a small number of flights.
“Ryanair sincerely apologises for any inconvenience caused by these unjustified ATC disruptions which are entirely outside of our control.”
EasyJet said: “Like all airlines, our flights to and from French airports, as well as those flying in French airspace, could be affected.
“We plan to operate our full flying programme to and from France on all days, however there is the potential of delays due to the industrial action, therefore we advise all customers to check the status of their flight on our flight tracker either on our mobile app or website.
“Please also be aware that public transport services may be affected by the strike.
“We recommend all customers allow plenty of extra time to get to the airport and consider alternative transport options where possible.”
