US Airways Dividend Miles members can earn double miles on all US Airways, US Airways Express or US Airways Shuttle flights through June 15, 2010. And the double miles will count toward Preferred status and award travel, giving you a head start on requalifying for elite status this year in addition to earning more miles for your next award flight. Registration is required at http://insideflyerus.wpengine.com/link/?2429 before making reservations so if you already booked flights on US Airways before registering for the promotion, those flights are ineligible for the 100 percent bonus miles.
