Both BA's and Seatguru's (know to take the latter with a pinch of salt) seatmaps are showing the exit row as row 9 but on MMB's seatmap it's showing the exit row as being row 10 (which I'm currently in)

Anyone know which is correct? Flight is LGW-AMS on 11/3 if that helps

Also - is there any chance of getting a blocked off middle seat in the front rows of ET? ET currently has row 4 as the front row but 4 B&E are currently free

thanks
