BERLIN—A union representing cabin crew at Lufthansa is expanding a strike campaign, announcing that it will stage all-day walkouts at Frankfurt, Munich and Duesseldorf airports on Monday.
The UFO union called Sunday on all members to walk out 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.
Lufthansa said it was canceling 929 flights to and from the three airports. It said that around 113,000 passengers would be affected by the cancelations.
UFO embarked Friday on walkouts expected to continue for a week, rotating around different airports, though it took a break Sunday. On Saturday, it called out members on the airline’s short- and medium-haul fleet in Frankfurt and crews in Duesseldorf.
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.
