Two members of German air carrier Lufthansa, wearing their cabin crew union (UFO) strike vests, walk through the Lufthansa terminal at the Fraport airport in Frankfurt, August 31, 2012. Lufthansa passengers face widespread flight disruption from Friday after 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, late on Thursday called on its members to strike from 0300 GMT to 1100 GMT on Friday in Frankfurt.
