Air France has suggested that Ryanair unfairly gave the media details about the claim, in which the low-cost airline accused the national flag carrier of increasing fares to compensate for fuel surcharges.
However, Ryanair the budget airline has staunchly denied this and said that it was fully within its rights to issue a press release regarding the matter on October 11 and is now looking forward to debating the matter in court.
Peter Sherrard, the airline's head of communications, said: "Ryanair looks forward to seeing Air France in yet another French court, on yet another silly claim by Air France.
"Air France has repeatedly raised its unjustified fuel surcharges within hours of many other high fares airlines and no amount of court cases can hide the fact that Air France is using unjustified fuel surcharges to increase fares for consumers.
"Ryanair didn't 'leak' this EU complaint to the press as Air France falsely claims.
"Ryanair issued a press release on Thursday, October 11 in order to provide the press with the full details of its EU price fixing complaint. It appears that Air France are not content with trying to limit competition and choice for air travel in France, now it seems they want to limit free speech as well."
