American Airlines has a new offer for buying AAdvantage miles. You can get up to 30% bonus through July 31, 2014.
The number of bonus miles that you earn is dependent of the purchase amount. You should buy 55,000 miles to maximize the bonus (16,500 miles) at the lowest per mile price.
This offer is valid for purchases made until July 31, 2014, and you can access it here.
The price of a mile purchased under this offer is 2.32 cents each when you purchase 55,000 that comes with 16,500 bonus miles for a total of 71,500 miles.
American was selling AAdvantage miles at 2 cents each back in February. US Airways tend to sell their Dividend Miles cheaper without yearly purchase cap. US miles will eventually turn to AAdvantage miles sometime in the early 2015.
