Lufthansa pilots represented by the Vereinigung Cockpit union have extended today’s industrial action until 24 November.
The airline has cancelled 876 short- and long-haul flights today.
It says the union extended the 24-hour walkout until the end of 24 November "for incomprehensible reasons… before Wednesday's strike even begun".
It adds: "They are inflicting extensive damage on our company.".
Both sides have argued before court. But the union says that two courts have ruled the walkout – which covers pay – is legal.
Union board member Jorg Handwerg blames management for the dispute's escalation. In spite of the court rulings, he states: "The employer's representatives were unable to propose improved offers."
Lufthansa says it wants to start mediation in the long-running labour dispute, which included previous arbitration efforts and covers a range of work and pension terms.
But earlier this year, the union requested limiting talks to pay negotiations and that other topics be left aside for the time being.
