The single best way to earn American AAdvantage Loyalty Points with credit card spending often flies under the radar, so I’d like to talk a little more about that in this post, especially since this tends to cause some confusion, and is also sort of unofficial.

In particular, I’d like to provide the update that this “limited time” opportunity has just been extended by two years, through the end of 2028.

With the American AAdvantage Loyalty Points program , you can typically earn one Loyalty Point per dollar spent on a co-branded American credit card. However, there’s one card that’s sometimes an exception and by far the best.

The Citi® / AAdvantage Business™ World Elite Mastercard® is the co-branded Citi and American Airlines business card. There’s a quirk to the card, though, when it comes to authorized user rewards . On this card, the authorized user ordinarily earns the Loyalty Points for their spending, and not the primary cardmember, which is an unusual policy for a small business card.

The catch is that there’s a limited time, targeted (at least in theory) promotion, that offers the ability to double dip. For those who are targeted (more on that in a bit), both the primary cardmember and authorized user earn Loyalty Points for spending. It basically means you earn two Loyalty Points per dollar spent, just in different accounts.

This is technically limited time — up until now, this has been valid through December 31, 2026, but this has now been extended by two years, through December 31, 2028. So that means AAdvantage members have a lot more time to qualify for status using this method.

Personally, this is how I qualified for AAdvantage elite status last year. I had a hard time justifying putting spending onto co-branded American cards compared to some other cards out there, when I was only earning one Loyalty Point per dollar. But if I can qualify for elite status for two people at once , and earn the corresponding Loyalty Point Rewards perks , the math on that spending starts to look much better.

With this double dip promotion valid through the end of 2028, I’m sure a lot more people are curious if they could apply for the Citi AAdvantage Business Card now, and still qualify for the opportunity?
