I booked an Emirates A380 service recently.
I actually chose the flights on the basis that it was A380.
That gives me 18.5 inches of seat width.
Very unhappy when the B777 was waiting at the gate.
My backside was not happy squeezing into 17 inches.
My shoulders were not happy either being bumped by everybody walking past either.
I find that seat width more important to me than pitch provided my 6'2" frame fits.
