Now and through the end of March, you will receive a 30% bonus (up to 12,000 miles) when you buy AA miles. The actual cost comes down to about 2 cents per mile which is not great for domestic coach awards, but not too bad if you are redeeming for international premium cabin awards.
And of course, all miles earned count towards lifetime status on American. There is a 40K cap per year on purchased or gifted miles.
Here is the link.
Terms and Conditions:
Members must purchase miles from the buyAAmiles® or giftAAmilesSM program between February 1 – March 31, 2009 to be eligible for the 1,500 mile bonus per 5,000 mile purchased offer.
Bonus is awarded to the purchaser of the miles. Please allow 72 hours for purchased miles to post to your AAdvantage account.
