of course its a big difference from the 777, its a much different aircraft.
you'll also have 28 seats with about 38' pitch. I'd rather be able to fly knowing i'll have 38' if I'm paying full fare economy than the slight chance of being upgraded and if not staying in coach.

But i dont think you will need to worry about NYC nights flights just yet, im pretty sure they will continue to be 777 - even after 744 leave the fleet ( with a bigger premium class offering)

I wonder what the plans are for the new 777 interiors.
