Ground staff of several Lufthansa companies will go on warning strike. Frankfurt and Munich will be hit hardest by the strike planned for 27 hours.

As a precautionary measure, the airline canceled between 80 and 90 percent of its approximately 1,000 scheduled flights for Wednesday. The strike is scheduled to end on Thursday at 7:10 a.m. Operations should have completely returned to normal by Friday. If flights within Germany are canceled, customers can use their flight ticket to take the train. Under no circumstances should passengers of canceled flights come to the airport.
