Air France faces four more days of strikes from next week as three unions announced fresh walkouts.

The latest industrial action is planned for May 3, 4, 7 and 8 as part of a long-running pay dispute with the French flag carrier.

The new strikes called by unions representing employees from pilots and cabin crew to ground staff, come ahead of a consultation the airline on management salary proposals.

Air France has suffered 11 days of strikes since February 22 at a cost of more than €220 million, which chief executive Jean-Marc Janaillac admitted was jeopardising the airline’s future.

The staff consultation on a 7% pay rise over four years starts today and runs until May 4.
