Lufthansa Group(BERLIN) — About 30,000 Lufthansa passengers will be affected by flight cancellations on Saturday as the pilots’ union continues to strike, according to the German airline.

Lufthansa said in a statement that although 95 percent of its flights were still on schedule, 137 were canceled because of the Vereinigung Cockpit pilots’ union’s continued strike against long-haul flights.

The 5,400 members of the union in Germany began their strike Wednesday, and are calling for an average annual pay rise of 3.7 percent over a 5-year period backdated to 2012, according to BBC. Lufthansa is offering 2.5 percent over six years to 2019.

“The status quo is that we pay our pilots significantly more than our competitors do,” Harry Hohmeister, chief officer of hub management at Deutsche Lufthansa, said in a statement. “As members of the executive board, we are responsible for more than 120,000 employees and want to keep Lufthansa viable for the future. That will not be possible with a demand for a 20 percent increase in pay.”

Hohmeister added that the German airline saw €10 million in losses per day from cancellations on the first two days of the strike.

Since Wednesday, 345,000 passengers overall have been affected by 2,755 flight cancellations, Lufthansa said.

Airlines owned by Lufthansa Group including Eurowings, Germanwings, SWISS, Austrian Airlines, Air Dolomiti and Brussels Airlines are not affected by the strike.
