Ryanair has condemned the "selfish actions" of the French aviation unions responsible for this week's industrial action, which has caused lengthy delays and cancellations for flights between France and other European destinations.

Hundreds of passengers flying with easyJet, Ryanair and British Airways will continue to face flight cancellations up until tomorrow, due to prolonged strikes being carried out by air traffic control in France.

Ryanair has cancelled around 200 flights today, including a number of routes between Dublin Airport and the French cities of Nantes, Nice, and Paris-Beauvais.

In response, Ryanair has called on the French Government and the European Commission to intervene in order to prevent passengers being "held to ransom" by "tiny numbers" of French workers.

Ryanair also pointed out that the strikes were also affecting flights overflying France, meaning that travellers whose whose flights neither take-off from or land in a French airport are also suffering.

The airline is now urging its customers to sign a petition to the European Commission, which it hopes will bring to an end the "repeated blackmail and disruption by ATC unions".

Head of Communications at Ryanair Robin Kiely said the strikes were "unwarranted" and "grossly unfair".

"Due to yet another French ATC strike - the 41st such strike since 2009 - we regret that we were forced to cancel a number of flights on Sunday, with further flights cancelled on Monday, and delays likely," he added.

A spokesman for easyJet confirmed that 82 flights had been cancelled, including 32 arriving and departing from the UK.

British Airways refused to disclose how many flights would be affected by the strikes, but said that it was doing "all we can to minimise disruption to customers affected."

A spokeswoman added that larger aircraft were now being used and some flights were being re-routed.
