What is the AA.com Lowest Fare Guarantee?
If you make a qualifying airfare purchase on AA.com and then find a lower American Airlines fare for the exact same itinerary on another Web site with a difference of $5 or greater, American will refund the difference in fare and give you a $50 Promotion Code to be used toward a future flight purchase. The lower fare may not be available on AA.com, and the claim form must be submitted by midnight Central Time on the same calendar day that the ticket was purchased on AA.com. The itinerary must also originate in the domestic 50 United States and be on American, American Eagle and AmericanConnection flights only, with purchase through the AA.com Web site.
