I need help!

I am an avid TWA FF. I have elite one status on TW (50K per year). My travel is so spread out that I can only accumulate about 50K on one airline and partners. AA has already sent me the package for platinum status. I need your advice. 1) Do I stick with AA? 2) Ask other airlines to match my status and what would be the best airline to do so.(most of my 50K mileage is domestic transcons LAX-DCA). I love to upgrade and nobody beats TWA for free and coupon upgrades! (I have not flown in coach on TW for over 12 years!) I just took a trip to MAD on DL in Business Elite and it was fantastic! Let me know your thoughts.
