Flew on a plane with the 'preferred' seat selection options (vs published e+). It still has the old AA seats, so it would follow that the first four rows of economy are the AA 'Main Cabin Extra' and there aren't any true e+ seats.

I got a CPU and noted that the window alignment is inaccurate on Aerolopa. Row 1 you have to lean a bit forward for the window, Row 2 has very limited window, Row 3 is ideal, and Row 4 is acceptable.
