A warning of Easter travel disruption has been issued due to planned strikes at Air France on Good Friday.
The industrial action is expected to impact the airline and its subsidiaries on March 30.
The Foreign and Commonwealth Office updated its travel advice to recommend that people check with their airline before travelling.
More walk-outs are planned for April 3 and April 7 in an ongoing row over pay.
The latest industrial action follows strikes by Air France staff on February 22 and last Friday, when a quarter of all flights were cancelled.
Negotiations are due to continue between unions and Air France management today (Tuesday) in an effort to resolve the dispute.
