Citi/AAdvantage credit card members can earn 10% miles back when redeeming AAdvantage miles through November 1, 2011. The bonus miles is maxed at 2,500 miles which is not too much, but still better than nothing. There is no registration needed for this promotion and the T&C state that bonus miles will post 6-8 weeks after the promotion end date. The one good thing is that since this is not a discount when redeeming miles, but instead a bonus back, these 2,500 miles should count towards lifetime status as long as they post in time by December 1. Since the promotion ends 1 month prior to the lifetime mileage program change for American, hopefully the miles will take less than 4 weeks to post. In my experience, American is usually very quick with posting miles, so I have high hopes.
UPDATE: I called American and they informed me that the promotion started August 20, 2011. The representative also thought this was targeted, but she did not seem confident in this. To see if you qualify, I would recommend calling American Airline customer service and inquiring.
Similar to the BankDirect Checking earning potential, I will continue to post new ways to earn miles to count towards lifetime status prior to the rules changing. And as always, if you have any tips, feel free to let others know in the comments section.
