The state labor court in Hesse, which includes Lufthansa's main Frankfurt hub, said today it rejected the airline's suit and found no grounds to declare the strike illegal.
The Vereinigung Cockpit union started a 35-hour walkout at Lufthansa's short-haul fleet mid-yesterday and extended it early today to the company's long-haul services.
The two sides have been fighting for months over the pilots' demand that Lufthansa keep paying a transition payment for those wanting to retire early.
