If you're short on AAdvantage Miles, you can top off your account by transferring rewards earned with American Airlines transfer partners directly into your AAdvantage account.
American Airlines is not a major transfer partner of any of the major travel rewards programs (AMEX, Chase, Citi, or Capital One), so your best bet when it comes to earning AAdvantage Miles will be Marriott Bonvoy and using AA's own co-branded credit cards.
AAdvantage Miles can be earned using several partners meaning that you can earn points with these programs and transfer those earned points directly to your AAdvantage account.
Out of these programs, Marriott Bonvoy is the best option for those based on the United States.
Marriott Bonvoy Points can be transferred to American Airlines AAdvantage at a 3:1 ratio which means that 3,000 Marriott Bonvoy Points can be converted to 1,000 AAdvantage Miles.
In addition to that, Marriott throws in a 15,000-point bonus for every 60,000 Marriott Bonvoy Points you transfer to an airline partners. When transferring to American Airlines AAdvantage, this gives you an additional 5,000 AAdvantage Miles.
So a 60,000-point transfer would give you a total of 20,000 AAdvantage Miles which is not too shabby if you don't plan on redeeming Marriott Points for free nights at Marriott brand hotels.
Marriott offers several credit cards that can net you a decent amounts of AAdvantage Miles once transferred, but you'll still want to consider American Airlines AAdvantage credit cards if you're looking to earn points faster.
