As above 2-4-2 excpet at the very back were it's 2-4-2 as the fuselage narrows.
The rows of 2 seats are very nice.
Surely you mean 3-4-3 except at the back where it's 2-4-2?
The pairs at the back of the plane are indeed very nice. You get a little bit room around you.
brs - why not have a look at
SeatGuru at the seating configs? I know there's 4 versions, but you can get yourself an idea of what to expect. And if you go to
V-Flyer you can find your flight and get a good guess at which version you'll have and the IFE onboard.
