Hamburg is canceling all departures on Thursday. All 126 planned departures at Hamburg Airport this Thursday will be “canceled or will take place without passengers” The airport company announced this on Tuesday after the Verdi union called for a warning strike for the aviation security forces.

Because of the strike, the central security checkpoint had to remain closed all day on Thursday, the airport said. The last time there were warning strikes in aviation security was in March last year. At that time it was about the working conditions of the employees, who had achieved significant wage increases.
