American Airlines has launched a Centennial Sweepstakes to celebrate its 100th anniversary in a special way: the airline is giving away 100,000 AAdvantage miles to 100 very lucky winners.

To enter the sweepstake for a chance to be one of the 100 AAdvantage members to benefit from the 100,000 free miles, do one of the following:

Enter the sweepstake every day using your AAdvantage number. There is no need to make a new purchase, but being an AAdvantage member is a must.
