This isn't a new issue. In October 2019, my spouse and I
​​​​​​couldn't buy gift cards during Earn Your Wings but then our minor child could. Tried numerous cards across both our CC billing addresses. At last 20 preauths went through. But 2 or 24 hours later we got cancellation emails.

​​​​​​Escalating repeatedly and offering to have even the AC Concierge office help verify us as higher than average spend elite customers did not help.

Then a week later, after they essentially told me to stop trying I could never buy-- I tried again and $2000 went through

One of the replies "Rita" wrote me back in Oct 2019:
"Upon secondary review of your purchase attempt, our system was unable to complete your recent online gift card order and therefore your order has been cancelled.

Our system uses a combination of internal and external tools, including information from your financial institution. With the information provided, our system was unable to verify"
