IBD note: You can exchange sign-up 25000 Dividend Miles miles (15K sign-up miles + 10K balance transfer miles) for a Mileage Saver round trip air ticket for US Airways. The card has $79 annual fee. My understanding is that the $99 certificate for two guests allows you to pay only $99 two have up-to 2 accompanying people with you. Please correct me if I am wrong.
