Lufthansa says some 113,000 passengers will be affected by 929 domestic and international flight cancellations due to all-day walkouts at three German airports staged by a union representing cabin crew.

The UFO union has called on all members to walk out Monday from 4.30 a.m. to 11 p.m. (0330 GMT to 2200 GMT) in Frankfurt and Duesseldorf and until midnight (2300 GMT) in Munich.

UFO embarked Friday on walkouts expected to continue for a week, rotating around different airports, though it took a break Sunday.

The union wants to secure transition payments for its 19,000 members if they retire early as part of its contract dispute with Lufthansa, which is trying to cut costs.

The strikes don't affect Lufthansa subsidiaries such as Eurowings, Germanwings, Swiss and Austrian Airlines.
