Lufthansa planes stand on the tarmac at Munich's international airport August 30, 2012. Passengers face widespread flight disruption from Friday after Lufthansa cabin crew representatives said they would start a series of strikes over pay and cost-cutting measures at Germany's largest airline. The UFO union, which represents around two thirds of Lufthansa's 19,000 cabin crew, would not say on Thursday which locations will be targeted or give the exact timing of strikes, saying only it would give six hours' notice.
