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.
