US Airways' CEO is trying to assure customers that the company's in no immediate danger of shutting down. Bruce Lakefield says the nation's seventh-largest airline filed for bankruptcy protection after it was unable to get 800 million dollars in annual cost cuts from its workers' unions. He says he believes employees will end up making "sacrifices" that will "keep the airline flying." Meanwhile, skittish customers are wary of booking the airline. One man says he'll wait "till things stabilize." He says he "can't afford to be canceled" out of a flight. It's the second time US Airways has filed for Chapter Eleven.
