On the seat map, Their are only 40 rows with 4 twin seats., The closest that i can find is the
Boeing 777-200 (772) Three Class Layout 2 but doesn't have any twin seats
Can you point me in the right direction, Which aircraft class type i am flying, Has it had a refit and is the layout on the BA Website correct since i might select the twin seats going out
40 rows and 4 sets of twin seats

It doesn't tell you to variant, but you can find out by trial and error. Many of the 200s have these dual seats.

I don't know if they are any good or not.
