US Airways is always very active at selling Dividend Miles. Their previous offer was also a 100% and those that participated to it just had the remaining 25% bonus deposited to their accounts couple of days ago.
This time, however, the bonus is instantaneous. US Airways will instantly double time number of miles purchases up to 50K Dividend Miles. The maximum number of miles you can buy through this offer is 100K at $1881.25. The Price of a miles is bit more than 1.8 cents. This offer is valid for purchases made from June 1st to June 30th, 2012. There is no need to register for this offer. The double miles will automatically show, when you go to do the purchase. The only requirement is that your Dividend Miles account has been open for 12 days before making the purchase.
This is a very good offer, if you have firm plans in mind how you would use the miles. Redeeming for international first and business class tickets on Star Alliance is the best option.
