You guys are constantly complaining about EVERYTHING at AA. Just so you know, the fleet managers are the ones who dictate the procedures and checklists, not the training department. Training simply, uh, trains.
Fyi, the AA Airbus checklist from beginning to end is a total of ONE page (two sides if you fold it). Additionally, the cockpit philosophy is of FLOWS. Yes, even at big, bad AA (where you guys think we can do no right).
The 737 checklist is a bit longer, but most of it is the Before Start and Shutdown, none of which have anything inane like "seatbelts - on" or "seats - adjusted".
Jeez guys. Chill out about AA.
