A union representing Lufthansa flight attendants escalated a bitter pay dispute on Tuesday, calling members out on strike at three German airports _ including the two biggest, Frankfurt and Munich _ in a showdown with an airline determined to bring down costs in the face of increasingly tough competition. Lufthansa scrapped many short- and medium-haul flights and said it also had to cancel about a third of intercontinental flights at Frankfurt _ among them services to and from destinations including Los Angeles, Houston, Chicago, Beijing and Mexico City. It listed around 200 flights as canceled Tuesday morning, most of them to and from Frankfurt.   (AP Photo/Michael Probst)
