Lufthansa pilots are striking once again, causing the airline to cancel about half of its scheduled flights from Monday until Tuesday at midnight.
About half of the flights on Germany's largest carrier were canceled as a result of the strike, which is the airline's ninth this year in the continuing dispute about retirement benefits.
About 150,000 passengers will be affected by the cancelation of 1,350 out of 2,800 scheduled flights. The strike is primarily focused on Lufthansa's inner-Europe flights on Monday, but was to be extended to long-haul flights Tuesday.
Lufthansa says the other airlines in its group -- Germanwings, Swiss, Austrian Airlines, Brussels Airlines and Air Dolomiti -- are not affected.
The strike follows failed talks with the Vereinigung Cockpit union, which is demanding Lufthansa keep paying a transition payment for those wanting to retire early. The airline wants to cut those payments, citing increasingly tough competition.
The union, which represents about 5,400 pilots, said in a statement that it regretted inconveniencing passengers. It also wants Lufthansa to reconsider raising the retirement age, which is currently set at 55, and is concerned about the pension plan changing for new hires.
