PARIS — Air France has warned fliers of travel delays and disruptions on Thursday due to a pay-related employee strike.

According to the airline, half of its long-haul flights departing Paris will be cancelled, 25% of medium-haul flights to and from Paris-Charles de Gaulle will be grounded, while approximately 15% of shorter flights will also be impacted. A number of U.S.-bound flights are expected to be cancelled as well, reports USA Today.

In total, the strike will impact a quarter of all Air France flights. Air France flights operated by the aircraft of any other airline, including HOP!, will not be affected by the strike.

Flights on KLM, part of the Air France-KLM group, will also not be affected.

Worker unions representing Air France pilots, cabin crew and ground staff called for a strike after their demands for a 6% pay rise were not met.

Air France is offering rebooking options at no extra cost, no matter the fare. As written on airfrance.ca., customers whose bookings are cancelled will be informed via SMA or email the day before their departure.

If a passenger has a valid Air France ticket issued on or before Feb. 19 for a flight operated by Air France or Joon on Feb. 22, they can move their trip to another date between Feb. 20-21, 2018, or postpone their trip between Feb. 23-27, 2018.

They may also choose to postpone their flight to sometime after Feb. 27, 2018, change their country of destination or origin, or cancel their trip. In these cases, Air France will provide them with a non-refundable voucher valid for one year, which can be used on Air France, Joon, KLM or HOP! flights.
