You can now use your miles to book any Economy Class seat for travel within the U.S.* for fewer miles than what's required for an AAnytimeŽ award. The number of miles required for Dynamic Air awards is based on published fares and will vary as fares vary.
American Airlines is pleased to offer this product in celebration of the 30th anniversary of the AAdvantage program. Dynamic Air awards are available to you in addition to MileSAAverŽ and AAnytime awards, so you now have more options and flexibility when redeeming miles for air travel
