AAdvantage is American Airlines' loyalty program. Participants earn miles for every flight they take on American or one of its partner airlines, as well as for money spent with more than 1,000 other businesses associated with the company. The miles can be used for future flights, hotel stays, car rentals or even gift cards. American has partnered with Points.com to handle the redeeming of miles for gift cards.
