The Air France-KLM group, Europe's second-biggest airline which is 17.6 percent owned by the French state, has been plagued by strikes and labour disputes in its French operations in recent years. The action is expected to last 24 hours.
Half of Air France's long-haul flights out of Paris were cancelled Thursday due to a strike over pay by pilots, cabin crew and ground staff. The waivers permit customers to make one change to their itineraries if the rebooked flight takes place by February 27.
In a Wednesday statement, Air France said it "plans to operate 75 percent of its flights in view of an estimated 28 percent of staff planning to strike" and "is making every effort to minimize the inconvenience".More news: Netanyahu associate to testify in corruption probe

It also warned that to ensure the maximum number of flights with reduced crew, it may have to limit the number of passengers on board some flights, meaning it can not honour all bookings.
Customers whose flight is cancelled will receive a full refund.
Salaries at Air France have been frozen since 2011. To be notified personally by AF Connect, Air France invites customers to update their contact details (mobile number and/or e-mail) in their reservation file on the company's website or in their Flying Blue profile. There's also an Air France app.
