TUIfly, part of London-listed holiday group TUI, was forced to cancel all of its 108 flights on Friday as many pilots and crew members called in sick, the German airliner said in a statement.
Germany’s third-largest airline company, which wants to merge with parts of struggling rival Air Berlin, canceled around half of its flights on Thursday under similar circumstances. Around two dozens of Air Berlin’s flights were also canceled on Thursday and Friday due to TUIfly’s staffing problems. TUIfly operates 14 planes for Air Berlin.
The labor action casts doubts about the feasibility of the airline’s plan to merge TUIfly with parts of Air Berlin as employees fear job losses and a deterioration of working conditions.
