Like others said, you basically go back to the terminal entrance, go through security (I've had success getting into the Fast Track lanes by showing an elite card, even when flying Economy). After security, you also might have to stop at the AA desk to get an AA boarding pass and answer some of those stupid security questions. After that, it's a bit of a hike to the gate, so allow time for that.
Things have changed, although not sure how recently. There is now a room/set of counters prior to security where one must get a BP to be able to go through security (used to be that no BP was required for this and one could go to the desk after to get it). If one has a valid BP, of course, no need to stop in the room.
If getting the BP there, they also ask the questions.
The new area has moved and now lets out much closer to the lounges and gates than previously. The hike is quite a bit shorter and does not involve going through the shops.

The connections counter that used to be after security often had a short line and we would stop there to avoid doing it at the gate. Failing that, we pop into the AC to answer the questions there. This way we can go to the gate just to board and not be shunted aside.
