$100 American Airlines Flight Discount

Earn a $100 American Airlines Flight Discount when you spend $30,000 or more in purchases on your
Citi® / AAdvantage® credit card during your cardmembership year (each 12 month period prior to your anniversary date) and your account remains open for at least 45 days after your anniversary. The Flight Discount expires one year from date of issue. The Flight Discount is redeemable toward the initial electronic ticket purchase of air travel wholly on flights operated by American Airlines, American Eagle or the AmericanConnection® carrier for itineraries sold and originating in the U.S., Puerto Rico and U.S. Virgin Islands. The Flight Discount is also redeemable for air travel on any oneworld® partner or American Airlines codeshare flight. The Flight Discount is redeemable online at www.aa.com. The Flight Discount is redeemable only toward the purchase of the base air fare and directly associated taxes, fees and charges that are collected as part of the fare calculation for travel on American Airlines, American Eagle or the AmericanConnection® carrier. The Flight Discount may not be used for flight products and/or services that are sold separately or non-flight products and/or services sold by American Airlines. If the ticket price is greater than the value of the Flight Discount, the difference must be paid only with a credit, debit or charge card, or with American Airlines Gift Cards. If travel booked with the Flight Discount is cancelled or changed by the cardmember, the Flight Discount will be forfeited and the cardmember will be responsible for any applicable fare difference and the applicable change fee. The Flight Discount will not be replaced for any reason. The Flight Discount is non-refundable, may not be sold and has no cash redemption value. If the $30,000 purchase requirement was met during your cardmembership year and your account remains open for at least 45 days after your anniversary, please allow 8-12 weeks for the Flight Discount delivery.
