French pilots are threatening a six-day strike next month that would impact the flights of easyJet, Air France and other airlines.
The main French pilots union, SNPL, is planning industrial action in protest against reforms by the French government which would no longer allow pilots to have their own separate representation in negotiations for collective working agreements.
Pilots are also concerned about cuts to their pensions.
If it goes ahead, the strike will take place on May 6-11.
EasyJet said it was aware of potential strike action which could affect all airlines operating to France but assured customers it would do everything possible to minimise any disruption.
