Yes, you can use your American Airlines AAdvantage miles to book hotels through the AAdvantage Hotels platform. In 2026, this system allows members to redeem miles for stays at thousands of properties worldwide, ranging from boutique hotels to major chains. While you can pay entirely with miles, you often get better value by using a "Miles + Cash" combination. Additionally, holding a Citi or Barclays AAdvantage credit card can sometimes unlock "member-only" rates or bonus miles on the cash portion of your booking. However, travel experts generally note that the "cent-per-mile" value for hotels is often lower (around 0.6 to 0.9 cents) than for flight redemptions (1.3 to 1.5 cents), so it is best used if you have a surplus of miles and want to reduce out-of-pocket travel costs.
