To all who get worked up about who gets off the plane first, I recommend taking domestic flights in China.
IME, as soon as the wheels touch the ground, regardless of whether or not the seat belt sign is still on, the Chinese passengers will bounce up from their seats, retrieve their bags and stand in the aisle - even while the plane is still rolling at speed. Nobody gets off any sooner, because it still takes the same amount of time for the plane to arrive, be parked and get connected to the air bridge.
On these flights, I just sat still until the mad rush was over.
After several of these flights, any system of disembarking in the US or other parts of the world seems very orderly!
When I am in a middle or window seat, I appreciate the courtesy of the aisle passengers who stand up and then stand back a little, so that I can also get up when it is the turn of my row to disembark.
