I have Citibank AAdvantage Mastercard. They are out of Sioux Falls South Dakota. Citibank has a website and so does American Airlines: Http://www.aa.com. I put my entire DVC purchase on my card and then paid some college tuition on it and got enough miles for an airline ticket. As you are probably aware it takes $25000 to get a domestic ticket so this practice isn't for everyone. I think the average person would either need a business or a couple kids in college to build up milage quickly enough. I run the tuition and most bills through the card and have gained enough miles for 8 tickets over about 3 years. It can work but you need to be able to pay the balances or plan on financing your credit card debt with home equity etc. Use it carefully. My Citibank AAdvantage card cost $50 per year so you can say the first ticket cost $50. If you don't pay your balance off monthly it is not worth it. Your finance charges will probably exceed the cost of your airline tickets. Good Luck.
