Even as they cut domestic capacity, U.S. airlines are looking to international routes to shore up flagging demand. "We're not solely focused on reducing capacity," says an executive at United Airlines, which just launched service from Washington to Dubai. "There are opportunities. Dubai is one we identified, and we're taking advantage of others, as well." Other carriers are following a similar strategy. Delta Air Lines has begun service to Mumbai and announced a new route to Monrovia, Liberia. European destinations are getting a boost as well, with US Airways set to offer seasonal service to Paris from both Charlotte, N.C., and Pittsburgh.
