to reset my credit limit and earn more AA miles? For example, let's assume I have a 25k credit limit. Can I charge 20k, then transfer 20k from my checking account, and then charge another 20k on the card, and earn 40k points during that period? Or similarly, can I transfer 25k to the card (when I have a 0 balance) and then charge 50k, to earn 50k points for that month? Ideally I'd like to be able to do this multiple times per billing cycle. Thanks for any help.
