AA is projected to hire very little off the street for the foreseeable future. If your hope is AA you'll be waiting a while. I would honestly focus your efforts more on UAL or DAL if you can get a check airman slot. Otherwise I would personally leave for another major like SWA, jetBlue or Spirit after you get some TPIC if there is no hope of a check airman position opening up.

It's not completely bleak but the few off the street hires AA will have are mostly going to go to the ex-mil crowd.

The good news is, if you want to leave for jetBlue, 500 TPIC is pretty competitive. They want guys that have a demonstrated ability to upgrade and not screw up but aren't top heavy with hours. That's pretty much their sweet spot.
