Debit card users can start racking up air miles on the nation's largest airline and also take a stab at winning one million miles. Citibank, American Airlines, and MasterCard have teamed to launch the 'Citibank AAdvantage Debit Card' this week. The card enables users to earn American Airlines 'AAdvantage' miles for all off-line or signature-only debit card purchases. The 'Basic Citibank AAdvantage Debit Card' has an annual fee of $25, earns one 'AAdvantage' mile for each $2 spent on qualified purchases and allows users to earn up to 60,000 'AAdvantage' miles per calendar year. The 'Premium Citibank AAdvantage Debit Card' has an annual fee of $65, earns one 'AAdvantage' mile for every $1 spent and affords users the ability to earn up to 100,000 'AAdvantage' miles per calendar year. New customers will receive up to 10,000 miles for opening a Citibank checking account and existing customers can receive either 2,000 or 4,000 bonus 'AAdvantage' miles respectively for converting. To launch the new card, the partners are launching a promotion with a 'One Million AAdvantage Miles' award to the 'Grand Prize' winner in an online sweepstakes. The contest gets underway Feb 1st, with sweepstakes information available at: www.sweepstakes.citi.com.
