Having these cards can get you 7,500 miles off your flight. You can even book one way awards. Thus a roundtrip economy flight will only cost you 17,500 AA miles and a one way will cost you 8,750 AA miles.
The website has a listing of city destinations that these reduced mileage awards will count for. In addition, you have to make sure that there is MileSAAver availability for your trip by first going to AA website.
For example, say I wanted to go to West Palm Beach, FL which is on the list for May. Only those dates in green for 12.5k each way will be available for reduced mileage awards.
In order to book these awards you must call this number 1-800-882-88801-800-882-8880. After you tell them your flights, you then must give them the award code listed on the website.
I’ve used these awards many time to save me money and miles. Also remember that having the AACiti card will also give you 10% back when you make award redemptions so this is even more in mileage savings.
