Remember, just before you close out one card start another and don't close the card until the air miles have hit your AA account. The miles reside with AA, not the credit card... you just have to wait for them to be posted to your AA account. Then close that old card and run with the other - when yuo sign up for the next one they will ask you if you have an existing AA Awards account - you give them you AA account # and those new miles then hit your account about a month after you've reached the $ volume of purchases in the required time frame. You generally need to switch from one bank's AA card to another as the offering bank won't let you cancel one and then apply for another inside of 2 years but who cares? There's no shortage of banks out there offering air miles cards.
