US Airways Dividend Miles members may remember last year’s Grand Slam promotion where members earned miles for using partner services. This year’s Grand Slam will run from Sept. 1 through Nov. 15, 2009 and members will earn one “hit” for completing a qualifying partner activity. For every four hits, members will earn bonus miles. Advance registration is required at http://www.usairways.com/grandslam or by calling (800) 428-4322. Members can earn up to 50,000 bonus miles, 4,000 of which are Preferred-qualifying.
