We have written extensively in a series of posts about the Citi AA Platinum Loophole. If you are new to this loophole, follow the links below to catch up:
We successfully applied for, and earned the bonus on, four rounds of Citi AA Platinum cards. This earned a significant amount of points for us. Amid rumors of the loophole being closed, I conducted a survey, which I described in Update #3. We decided to apply for our 5th round of cards, and I am sad to report that neither of us got a bonus tracker on our account.
Do not misunderstand me. I am not declaring that the loophole is closed completely, but I am adding our datapoint to the mix. We applied via a public 50,000 point link. Brooke had closed one of her World Elite cards, and I had product-changed mine to a Double Cash. Neither of us got a bonus tracker on our latest cards. For us, this will be the end of the line with this particular loophole. As a point of reflection, we were able to earn a total of 460,000 AA miles using only this loophole. Add that to the points we earned from our Barclays US Airways cards, Citi AA Executive Cards, and Citigold Checking accounts, and we should be ok for a little while :).
If you choose to apply for an additional round of AA Platinum cards, do so at your own risk. Good luck!
