Though workers from SNPNC-FO and UNAC unions said their strike is to start on Christmas, there are no flights scheduled that day, so the walkout will only impact travellers flying on December 26th.
EasyJet said it doesn't know exactly how many workers are to down tools, but anticipates fewer than half of flights will be impacted.
The British airline will know the extent of the strike Tuesday because aviation workers are legally obligated to announce strikes 48 hours in advance.
The workers are upset over the number of changes made to their schedules and have demanded a larger share of the company'sm profits.
EasyJet employs some 600 flight attendants among its roughly 1,000 workers in France.
