As stated in the SPG Forum by the Lurker it was Amex decision to drop SPG Plat, stated by my Amex Callcenter team was that it was Starwoods fault. It looks like the Lurker was right and any company may buy SPG Plat from Starwood as a benefit for its top customers. Amex just is not willing to pay as much as AA. Disgruntling.
