The Independent Flight Attendants’ Organisation (UFO) announced the strike late Wednesday, a day after its members staged eight-hour walkouts at three key German airports in a dispute over pay and conditions.

The strike Friday will hit Frankfurt, Berlin, Hamburg, Munich, Düsseldorf and Stuttgart, said a statement on the union’s website.

Lufthansa spokesman Michael Lamberty told news agency AFP, “We still hope that it’s possible to avoid a strike and return to the negotiating table.

“We are cancelling two-thirds of flights so that our customers can find alternatives. It is important that we inform them early enough.”
