Ryanair says there is "high possibility" of further disruption
Ryanair says it is to cancel scores of flights for a second day on Tuesday due to an air traffic control strike in France.
In a statement, the Irish carrier says: "We regret to advise customers that due to a strike by French air traffic control unions we have been forced to cancel a number of flights."
It says customers will be updated on their flight status through e-mail and/or a mobile phone number, if they provided one at the time of booking.
Passengers are being advised to check the status of their flight before travelling to the airport.
Ryanair alo says there is a "high possibility" of further disruption and/or cancellations as French unions are planning further action.
The industrial action in France is set to continue until Friday evening.
Reports say the action is over a dispute about working hours and conditions.
The Airlines for Europe group has warned the strikes could result in more than 1,000 flight cancellations across Europe, as well as severe delays.
The French Civil Aviation Authority (DGAC) has asked airlines to reduce their flight schedule between west and south of France, the Iberian Peninsula, Italy and North Africa.
