Lufthansa is set to face another round of strikes after cabin crew union UFO said it would take more action from Thursday.
The union staged eight days of industrial action earlier this month forcing the cancellation of around 4,700 Lufthansa flights.
The union is now calling for its members to walk out again on Thursday and Friday (November 26-27) and the action could continue into next Monday (November 30).
UFO leader Nicoley Baublies said the action would continue into Monday if Lufthansa did not agree to the union’s demands for more “wide-ranging” talks over pay and conditions for cabin crew.
The long-running dispute, which has been going on for nearly two years, is over pay and early retirement benefits.
Details of which flights will be affected by the latest strike have yet to be announced.
Lufthansa said in a statement: "Lufthansa is trying to keep the effect of the strike on its customers as low as possible.
"At the moment, no concrete strike actions are announced, hence the effect of these strike actions on flight operations cannot be estimated at this point in time.
"As soon as these effects are known, Lufthansa will set up a goodwill policy for all booked passengers. Passengers booked on a flight which has to be canceled due to strike actions, always have the opportunity to rebook once or cancel their flight free of charge."
