We love our Blue Sky AMEX card. We really use it more than the Disney Visa and there so many more options to spend the rewards. The advantage over US Air is that you can use the money on any travel. The rewards can be used in $100 intervals. As long as you have a qualifying purchase on your card, you just apply it directly to your statement on the website. Super easy to use. We have used it for hotel stays (doesn't matter which hotel), Carnival cruise statements, Disney World dining plan purchase, etc. We have really enjoyed the flexibility. This may not be the exact amount, but I think we get $100 for every $7500 of regular charges. I think if you book travel through the site that there may be a better exchange. There is also no yearly fee and the card is super cool and always catches the cashier off guard.
