They requested a copy of my AAdvantage Platinum card (which shows my number and the expiration date) and a current printout of My AAdvantage account. Then I wrote up an email that included my reservation info for an upcoming 7200 mile roundtrip, explained how American made me fly many more miles for the same destination, and listed a few more planned trips. I think I'll earn the 50,000 miles next year and I said so.

I got an email back from a "OnePass Partner Liaison Representative" telling me "it is my pleasure to inform you that your request for Elite status has been granted", and when I logged in to CO my account said Gold.
