Verdi sees the warning strike at Lufthansa as a great success. Of the more than 1,000 flights originally planned, up to 90 percent were canceled on Wednesday.

More than 100,000 passengers had to change their plans. Negotiations are stalling with cabin crew and with the crews of the holiday flight subsidiary Discover Airlines. The Federal Association of the German Aviation Industry (BDL) tried to de-escalate the situation. “I appeal to the unions to shape the further collective bargaining rounds with a sense of proportion,” said BDL President Jost Lammers.
