I think (having not seen the outside of the bird) that this was an ex-TWA 757, as while the seats had been MRTC-ized in terms of space, they were not the new blue variety, and the overheads looked to be stock 757 models. </font>
TWA and AA planes are not integrated into one fleet at this point. AA planes are still operated by AA, TWA planes are still operated by TWA planes.
Unless your flight was in the 2600-3200 range, you were on an AA aircraft.
