Don’t forget, through November 30, 2012, you can purchase US Airways Dividend Miles and receive a 100 percent bonus on your purchase. US Airways will sell you miles in 1,000 mile increments, up to 50,000 miles. Buy 50,000 miles and receive a 50,000 mile bonus. I don’t recommend buying miles just for sake of buying them, but if you have an award in mind, this can be a pretty decent way to top off your account.
