Be advised that the seat map posted by Sabena332 is the NEW
cabin version, which does not yet exist on the 772s.
The version of the 772s is 12P 56J 202Y.
The bulkhead row is row 21. The "wall" is perfect because there is an indentation that allows for extra leg room.
The emergency exit row is row 35, with no "wall" infront.
All seats recline and the configuration is 3-3-3 across.
