Cabin crew at Lufthansa staged a second day of walkouts on Saturday, but the German airline was expecting a strike-free day on Sunday.
On the second day of a planned week of protests over failed pension talks, Lufthansa cancelled 520 short-haul flights, affecting 50,000 passengers, virtually all of the flights operated by its main Lufthansa brand out of Frankfurt.
Lufthansa spokesman Andreas Bartels told Reuters TV that long-haul flights were operating as planned.
