It’s still not for me, but promos for buying US Airways and American miles have returned. With US Airways, buy 50,000 and get 33,000 bonus miles. And from American, buy 80,000 and get 28,000 free. These miles will obviously combine at some point, so I consider this to be a valuable currency right now. What about the price? Around 100,000 miles for around $2,000 isn’t a terrible deal in this case. But if you hesitated getting the 100,000-mile American credit card because of the $450 annual fee, you should be kicking yourself right now.
