Landing Page for Buy/Share/Gift US Miles Share: 75% bonus on shared miles. Sharing max 50K at 1cpm with 7.5% tax and $30 fee comes to $567.50 and nets 37.5K miles for a cost of 1.5cpm. Not horrible but not great at all in comparison to the 100% bonuses of old. Those worked out to 1.1cpm. The terms of the share page say this is valid now through May 15th at 11:59pm Pacific. This conflicts with the landing page for Buy/Share/Gift that says now through May 31st. Par for the course with US Promotions. Buy/Gift: If you have the US Airways branded credit card (Either the Mastercard or Visa is applicable), you can buy OR gift up to 50K miles at 50% off. Charges must go on the US Airways card, you're restricted to those two choices if you are deemed worthy. 50K at 2.75cpm costs $739.06 after taxes, or 1.47cpm. Same cost as previous 100% bonuses. Just limited to 50K now, unfortunately. Terms for Buy/Gift indicate this is valid now through May 14th at 11:59pm Pacific - Note this is a day earlier than the Share promotion.
