"The maximum number of AAdvantageŽ bonus miles that can be earned annually from this benefit is 10,000 AAdvantageŽ bonus miles per calendar year and per AAdvantageŽ account, regardless of how many AAdvantageŽ miles you redeem in that calendar year, and regardless of how many AAdvantageŽ co-branded credit cards you have."
