Lufthansa did not specify how many flights would be cancelled but said it expects extensive disruptions. The airline's cargo division and regional subsidiary CityLine are also affected.

Lufthansa cancelled hundreds of flights across Germany on Thursday as pilots and cabin crew staged a coordinated 24-hour strike in disputes over pensions and job security.

The walkout began at 12:01 am and runs until 11:59 pm, affecting all departures from German airports including major hubs in Frankfurt, Munich and Berlin.

The strike involves approximately 4,800 pilots represented by Vereinigung Cockpit union and around 20,000 cabin crew members organised by the Unabhängige Flugbegleiter Organisation, who are conducting parallel actions over separate disputes.

Lufthansa did not specify how many flights would be cancelled but said it expects extensive disruptions. The airline's cargo division and regional subsidiary CityLine are also affected.

Airlines outside the Lufthansa Group, including Ryanair, Easyjet and Condor, continue operating normally. Within the group, Swiss, Austrian Airlines, Brussels Airlines, ITA Airways, Eurowings and Discover are not part of the strike call and will fly as scheduled.

Lufthansa said it expects to resume normal flight operations from Friday.
