How can AAdvantage members earn miles through hotel stays?

AAdvantage members can earn miles through hotel stays primarily by booking accommodations with partner hotels and providing their AAdvantage number at the time of check-in or reservation. This partnership allows members to accumulate miles that can be redeemed for flights, upgrades, and other travel-related benefits, ensuring that their stays contribute to their overall mileage balance.

This system incentivizes members to choose specific hotel partners, fostering loyalty not only to American Airlines but also to the hotels within their network. Members can take advantage of this by simply ensuring they enroll their AAdvantage number in their reservation, which triggers the automatic credit of miles after the stay is completed. This process is straightforward and provides a substantial benefit to frequent travelers who utilize both airline services and hotel accommodations.

The other choices present scenarios that do not accurately reflect the AAdvantage program's earning structure. For instance, staying at any hotel without a partnership would not yield AAdvantage miles, promotions may provide opportunities for bonus miles but do not represent the standard earning method, and using an American Airlines credit card alone does not pertain specifically to earning miles through hotel accommodations.
