Lufthansa faces a renewed threat of strike action this week with a possible walk out by cabin crew.
Week-long industrial action could run from Friday if the German carrier refuses to meet cabin crew union demands on retirement and pension benefits.
Flight attendants’ union UFO on Monday said it would call for a strike on November 6-13 if the airline did not respond to its demands with a serious offer.
The head of the union, Nicoley Baublies, said he did not expect Lufthansa to come around after two years of negotiations.
“All passengers are advised to assume that their flights will not take off,” Reuters reported him as saying.
Lufthansa said it regretted the strike threat and said retirement benefits for its flight attendants were already industry-leading in Germany.
The cabin crew union threatened strikes over the summer but relented after management made some compromises.
The carrier is also in talks with its pilots, who have staged over a dozen strikes in 18 months. Strikes this year have so far cost Lufthansa €130 million, it said last week.
