People travelling abroad face delays and cancellations as French air traffic controllers (ATC) go on strike again.

Airlines have already been forced to cancel three flights from Manchester Airport this morning (September 15) due to the 14th French ATC strike to take place this year.

The strike action launched on Wednesday evening (September 14) and is expected to continue until Friday (September 16).

A Ryanair flight travelling from Manchester to Barcelona this morning has been cancelled, while Flybe have been forced to cancel their 5.10pm flight to Paris Charles De Gaulle Airport today.

An EasyJet flight heading to Bilbao from Manchester Airport this evening has also been cancelled.

A warning on the website for Liverpool John Lennon Airport reads: "Strike action by French ATC services on 14th-16th September 2016 may affect flights to or from France, as well as those over French airspace.

"If you're due to fly, please contact your airline directly for further information."

A spokeswoman for Manchester Airport said it is unknown at this stage if any more flights will be disrupted.

More than 100 flights have been cancelled altogether across the UK due to the strike.

British Airways has offered customers due to fly to or from France on Thursday the opportunity to rebook.

The carrier will use larger aircraft where possible to enable passengers whose flights are cancelled to reach their destination.

A British Airways spokeswoman said: “Yet again the French air traffic control trade unions are causing unnecessary frustration and disruption for customers.

“We continue to urge the French government and the trade unions to resolve their issues so that customers can go on their holidays and business trips without these frequent threats of strike action hanging over them.”

Robin Kiely, head of communications at Ryanair, said: “It’s reprehensible that Europe’s consumers repeatedly have their holiday and travel plans disrupted or cancelled by the selfish actions of ATC unions, who use strikes as a first weapon rather than a last resort.

“This French ATC strike will impact hundreds of thousands of European consumers and throw their travel plans into chaos once more.

“It’s high time that the European Commission takes action to prevent these repeated ATC strikes from continuously disrupting the travel plans of millions of Europe’s citizens and their families.”

A spokesman for easyJet said: “EasyJet is disappointed at this unnecessary strike action causing further disruption for passengers and airlines across Europe.”
