In mid-November American offered a purchase miles bonus that I thought was a bit disingenuous to tie to ‘Cyber Monday’. It was still a good deal as far as purchase miles bonuses go, just not credible to call a “second half of November sale” a Cyber Monday deal. And indeed they extended the offer through January 4.
Now US Airways Dividend Miles American AAdvantage is back selling miles at a discount, and again with a bit of a confusing offer — this time offering a stackable bonus and a discount, which I suspect just makes things more confusing, but does allow you to buy 142,500 miles at 2 cents apiece.
