AAdvantage Transfer Calculator
The AAdvantage Transfer Calculator will calculate the conversion of rewards from other programs to AAdvantage Miles. You can enter any amount of AAdvantage Miles in the table below. It will output the total amount of points needed in the partnering program(s) to equal the amount of AAdvantage Miles you specified.
Earning With Partner Credit Cards
All of the credit cards listed in the table below allow you to earn rewards and transfer them directly to your American Airlines AAdvantage Account. This gives you alternative ways to earn rewards through spend and sign up bonuses. The earning rates listed are based on the transfer ratio when converting rewards to AAdvantage Miles. You can use the Search By Transfer Partners tool to get a list of credit cards that earn rewards with a specific program.
Summary
Most of AA's transfer partners are good for topping off your account, but none of them will really earn you a great return on AAdvantage Miles on day to day spend. Since American Airlines is not partnered with any of the major rewards programs that allow you transfer points, you're best bet for earning AAdvantage Miles will come from using AAdvantage credit cards.
