FRANKFURT (Germany): Up to 90 percent of Lufthansa’s flight schedule will be cancelled Wednesday due to a walkout by ground staff, the carrier warned, the latest strike-related travel chaos to hit Germany. Some 25,000 staff will take part in the walkout over pay, which will last for around 27 hours from 4:00 am (0300 GMT), the union Verdi announced this week.

The strike will affect Germany’s biggest airport in Frankfurt as well as those in Munich, Hamburg, Berlin and Duesseldorf. “Due to the strike, we currently assume that around 10 to 20 percent of the Lufthansa airline programme will be possible” on Wednesday, the carrier said in a warning to passengers online.

“Please only come to the airport if your flight has not been cancelled,” it said, adding that counters to rebook flights would also be closed due to the industrial action. The airline had previously warned up to 100,000 passengers would be affected. Lufthansa ground staff are demanding a 12.5-percent pay increase over 12 months as well as one-off bonuses to counter inflation, according to Verdi.
