Continental Airlines is switching allies in the battle to attract more international customers and keep them flying on its partner airlines. Continental will become part of the Star Alliance, which includes US Airways, United and Lufthansa. That means that eventually you will probably be able to exchange miles in one of the carrier's frequent-flier programs for flights on another airline (provided, of course, you can manage to use your miles at all). Continental had been a part of the Sky Team, but didn't think that was a good idea after fellow members Northwest and Delta decided to merge into a new Delta.
