Rob got this offer with his Citi/AAdvantage Gold World Elite MasterCard.
Upon enrollment, you can earn 3X AAdvantage miles on purchases ONLINE through 06/30/17. You can earn up to 2,500 AAdvantage bonus miles.
As usual, for me, due to this 2,500 bonus mile limit, I will likely not even entertain this offer. I really can’t do anything with 2,500 miles and I do not want to forgo using my other main cards like my Chase Freedom Unlmited card for a mere 2500 miles. But if you are trying to accumulate American AAdvantage miles, then you should take “advantage” of this offer if it is available to you.
