Half of Air France long-haul flights from Paris will be grounded today due to strike action, the airline warned.

The dispute will also affect other services with only three quarters of medium-haul flights operating and 85% of short-haul departures.

“Furthermore, in order to ensure the maximum number of flights with our reduced crew, we may have to limit the number of passengers on board some of our flights, meaning that we will not be able to honour all bookings,” the airline said.

“Air France flights operated by an aircraft other than that of Air France or Joon will not be affected by this strike.”

The disruption is being caused by a walk out by members of several Air France unions in a dispute over pay.

The airline estimates 28% of its staff will participate in the industrial action with employees demanding a six per cent pay rise across-the-board.

Management is offering a basic increase of one per cent, to be paid in two instalments and a range of incentives, which trade unions have dismissed as “small change” according to French reports.

The Foreign and Commonwealth Office updated its travel advice for France today and said: “Strike action by Air France on February 22 may cause delays. If you’re travelling during this period, you should check details with your airline.”

Air France said: “If you have a valid Air France ticket, issued on or before February 19, for a flight operated by Air France or Joon on February 22, you can postpone your trip between February 23 and 27, 2018.

“If your reservation is cancelled, we recommend that you do not travel to the airport. Our staff will do their utmost to offer you an alternative solution.

“If your flight is cancelled or delayed by more than five hours and you decide not to travel, you can obtain a refund for your ticket by contacting a point of sale directly.”
