A German court issued an injunction Wednesday ordering a halt to a strike by pilots at Lufthansa, Germany’s biggest airline, that caused the cancelation of 1,000 flights.

Lufthansa welcomed the ruling by the state labor court in Frankfurt but said that a special, reduced timetable it had drawn up for the day would remain in place. It said that largely normal services would be resumed on Thursday.

The pilots’ union, Vereinigung Cockpit, has been calling regular short-term strikes in the long-running labor dispute, which comes as Lufthansa restructures to meet increasing competition from Gulf airlines. The pilots want the airline to keep making transition payments for those seeking early retirement.

The court found that the union’s aims went beyond that demand, to exerting more influence on Lufthansa’s new low-cost operation, making the strike illegal, news agency dpa reported.

Vereinigung Cockpit began its strike on long-haul flights Tuesday, forcing the cancellation of 90 flights, and extended the walk-out to medium-and short-haul flights Wednesday.

Union spokesman Markus Wahl told n-tv television after the ruling that it had told pilots to be available for work immediately. Wednesday’s ruling overturned one by a lower court on Tuesday that went in the union’s favor.
