US Airways Grand Slam promotion, which I’ve already detailed some of the pluses and minuses of, is now open for registration.
Activities don’t begin to count for the promotion, which offers the potential to earn up to 110,000 bonus miles, until September 14th. But best to register so that you don’t forget, more than once I’ve thought enough about a promotion that I’ve assumed I had registered, when I had not. And of course there is no downside to registering.
