With mileage junkies constantly searching for ways to earn even more miles, American Airlines has developed an interactive tool to help customers uncover additional earning opportunities, providing a faster route to free travel. Available on AA.com, the AAdvantage Mileage Maximizer ( http://www.aa.com/max ), includes a brief questionnaire that shows customers how simple changes to routine activities can earn them a lot more miles.

Anyone with an AAdvantage account can give it a try, and between now and Sept. 30, members can enter the “Max to Relax” promotion for a chance to win prizes, including an all-inclusive vacation to the Caribbean.
