Contacting AA and US will be less useful than flaming them in every public forum imaginable. Make it into a media firestorm if you really think it will help.
Or, better yet, vote with your wallet. Fly B6, fly VX, buy F and connect on another legacy (DL has recently been undercutting AA's first class fares in many domestic markets).
And, most importantly, remember that you are not hub captive. Every AA hub has plenty of service on non-AA airlines.
I'm happy to buy a first class ticket and connect through ATL on DL (the bourbon's better anyway) if I can save money and send an economic F-you to AA.
