Earn 50X AAdvantage Miles on Cancer Donations
Loading article…
American Airlines is running one of its most generous earning promotions of the year, and it has nothing to do with flying. Through September 30, 2026, you can earn 50X AAdvantage miles per dollar donated to Stand Up To Cancer when you pay with an eligible AAdvantage Mastercard. A $100 donation therefore returns 5,000 miles.
In this article, we explain how the offer works, which cards qualify, and how the math compares with buying miles outright. We also list the limits you should check before you donate. If you want a card that qualifies, start with our guide to the best credit cards.
How the 50X AAdvantage Miles Offer Works
American runs this promotion with Stand Up To Cancer every year, but the 2026 edition pays far more than usual. You donate through the dedicated AAdvantage promotion page, enter your AAdvantage number, and pay with a qualifying card. The earning rate then depends on how you pay.
| How you donate | Miles per dollar | Minimum donation |
|---|---|---|
| Eligible AAdvantage Mastercard, via the promotion page | 50X | $25 |
| Any payment method, AAdvantage member | 25X | $25 |
| Standard rate outside this promotion | 10X | None published |
The promotion started on August 13, 2026 and runs through September 30, 2026. However, the 50X tier can end early: American caps it once qualifying Mastercard donations reach $5 million in total. Consequently, the sooner you donate, the safer your rate.
What the Miles Actually Cost
At 50 miles per dollar, each mile costs 2 cents. For comparison, American’s current buy miles promotion prices miles at 2.26 cents each, so the donation route comes out slightly ahead. You can see every current offer in our guide to buying points and miles.
Still, be honest about the math. We value AAdvantage miles at roughly 1.55 cents each, which sits below the 2 cents you pay here. In other words, this is not a clever way to stock up on miles at a discount. Instead, treat the donation as the point and the miles as a rebate on money you were already prepared to give.
Which Cards Earn 50X
Six U.S.-issued AAdvantage Mastercard products qualify for the top tier, provided the account stays open and in good standing. Both Citi and Barclays issue eligible cards, so most AAdvantage cardholders can take part.
Business and no-annual-fee AAdvantage Mastercards also appear on American’s eligible list. Therefore, check the promotion terms against your specific card before you assume the 50X rate applies. Visa and American Express cards earn the 25X rate instead.
Limits and Fine Print
The terms are short, but a few of them matter. Review these points before you enter an amount.
- Donation minimum and maximum: You must give at least $25, and each transaction caps at $10,000.
- The 50X tier can end early: American stops it once qualifying Mastercard donations reach $5 million, or at 11:59 p.m. PT on September 30, 2026, whichever comes first.
- Miles arrive slowly: American credits the miles by December 1, 2026, so do not count on them for a booking this fall.
- No elite status progress: These are bonus miles, not Loyalty Points, so they do not move you toward AAdvantage status.
- Donations are final: A charitable gift cannot be reversed if you change your mind about the miles.
Bottom Line
Earning 50X AAdvantage miles on a donation is the strongest version of this annual promotion we have seen. At 2 cents per mile, it undercuts American’s own buy miles pricing, and it turns a charitable gift into a meaningful pile of miles. A $500 donation, for example, returns 25,000 miles.
That said, the rate still sits above what we think an AAdvantage mile is worth, so give because you want to support the cause rather than to speculate on miles. If you plan to donate, use an eligible Mastercard and do it early, before the $5 million cap closes the 50X tier. To catch offers like this as they launch, subscribe to our newsletter.

50X AAdvantage Miles — Frequently Asked Questions
How do I earn 50X AAdvantage miles on a donation?
Donate at least $25 through American’s dedicated Stand Up To Cancer promotion page, enter your AAdvantage number, and pay with an eligible U.S.-issued AAdvantage Mastercard. Every other payment method earns 25X instead. The offer runs through September 30, 2026.
When does the AAdvantage donation offer end?
The promotion ends at 11:59 p.m. PT on September 30, 2026. However, the 50X tier stops earlier if qualifying Mastercard donations reach $5 million before that date, so the effective deadline may arrive sooner.
How much does each mile cost with this offer?
At 50 miles per dollar, each mile costs 2 cents. American’s current buy miles promotion prices miles at 2.26 cents, so the donation route is cheaper. Even so, we value AAdvantage miles at about 1.55 cents, which means you are paying a premium.
Do the bonus miles count toward AAdvantage elite status?
No. American treats them as bonus miles rather than Loyalty Points, so they do not help you reach Gold, Platinum, Platinum Pro, or Executive Platinum. They only add to your spendable balance.
When will the miles post to my account?
American credits the miles by December 1, 2026. Because that timeline stretches past the promotion itself, avoid donating with a specific fall trip in mind. Plan any award booking around a spring departure instead.
Which AAdvantage credit card should I use?
Any of the six eligible U.S.-issued AAdvantage Mastercard products works, including the Citi® / AAdvantage® Platinum Select® World Elite Mastercard® and the AAdvantage® Aviator® Red World Elite Mastercard®. Compare them in our best American AAdvantage credit cards guide.
