Earn 700 American Airlines Miles in Five Minutes

You can earn 700 AAdvantage miles by entering American Airlines' Miles for Milestones giveaway, a celebration of the 35th anniversary of the American Airlines AAdvantage® program. 35 winners will be chosen for the grand prize of 350,000 AAdvantage miles.                                                           _

Getting approximately $12 worth of miles for about five minutes of work is a great deal for me, especially since it resets the expiration clock in your American Airlines account, extending your entire mileage balance's expiration for 18 months.
