Amex AU backdating question

[Stiga9]

Sorry, yet ANOTHER Amex backdating question. I couldn't find the answer to this:

I have one Amex card: Member since 2011. My sister's current Amex says Member Since 2004. If she adds me as an AU, can I get my member since date back to 2004? I would love to be like Marty McFly and go back in time.

I don't know the answer to this but I think the chicken has to come before the egg. I think you have to be an AU first then get your own account to go back. I don't think you can open a new account (first relationship with AMEX) then get added as an AU and have your account go back to 2004.

That's definately my guess. However, i'm hoping someone in this MyFICO world gave it a shot and see if it worked!

Thanks for your input.
