A member of German air carrier Lufthansa cabin crew union "UFO" stands at a strike post outside a Lufthansa office building at the Fraport airport in Frankfurt, September 4, 2012. Lufthansa passengers face widespread flight disruption after cabin crew representatives said they continue 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 0400 GMT to 1500 GMT on Tuesday in Frankfurt and Berlin's Tegel airport from 0300-1100 GMT.
