SAPMAN,
How do you know you're qualified Platinum already for 2002? I'm curious, did the Aviators Service Center tell you that? The reason I ask is because it is obviously much easier to get Platinum on TWA as opposed to American (American require 150,000 miles on discount tickets).
If you've found out that you are already Platinum on TWA through 2002 (ie till Feb 2003) then I might seriously consider making a run for Platinum on TWA, I'm currently Elite 1.
