Sorry, that was confusing. You do not become Premier with an "American" amex Platinum, but you do become Premier with a Fairmont credit card. If I could become Platinum with my "American" amex Platinum, I surely would.
I sent an email to the manager of the Georgetown Fairmont, but I will send a letter (hard copy even) to Fairmont Corporate. I am a lawyer, so I do have nice stationary with letterhead-maybe that will get the ee more of a bonus!
