That's been going on for sometime now. The only viable economic aircraft for the near future in the seat range AA wants is the Embraer 195. My guess is an acquisition/merger with Jet Blue and an E-195 order by AMR.

Whether the 195's would go to AA mainline or JB is the wildcard. Those aircraft (in whomever's hands) would take a lot of the former AA flying that Eagle is now doing with the smaller (and economically dead) Embraer's. If AMR and the APA are really as cozy as the claims, then I'd think those aircraft would go to AA and the Jet Blue operation would either be folded into AA or operated as a single pilot seniority list (AKA "airline within an airline").

Let's see if the very near future has any bombshells.
