US Airways and American Airlines, whose proposed merger has been stalled by U.S. government opposition, urged a court on Friday to require the Justice Department to turn over documents relating to its approval of four previous airline mergers, Reuters reported on Friday. The Justice Department filed a lawsuit on Aug. 13 to stop the planned merger of US Airways and American's parent, AMR Corp., arguing that the deal would lead to higher air fares and other fees. A judge will hear the case without a jury in November and decide whether the deal can go forward. The airlines have said that the merger is needed to help them compete in a rapidly consolidating industry.
