As of early 2026, there is no direct, official way to transfer American Airlines AAdvantage miles to the Hilton Honors loyalty program. Frequent flyer miles and hotel points are generally not interchangeable between these two specific partners. While you can sometimes use AAdvantage miles to book Hilton hotel stays directly through the American Airlines "Hotels" portal, this typically offers a much lower "cent-per-point" value compared to flight redemptions. If you are looking to move points into Hilton, the most common route is through American Express Membership Rewards or Bilt Rewards, which both maintain 1:1 or better transfer ratios with Hilton. Occasionally, third-party "points exchange" platforms like Points.com may facilitate such trades, but these often involve hefty transaction fees or poor exchange rates that can devalue your miles by more than 50%. Most travel experts recommend keeping your AAdvantage miles for high-value flights and using a co-branded Hilton credit card to build your hotel point balance instead.
