Economy on this aircraft is configured 2-4-2 (A,C - D,E,F,G - H,K), except where the cabin narrows at the back when it is 2-3-2 and seat E is missing.
The first row of economy does not offer any extra space, but the first row in the second section does. We can only say this for certain for seats 35 C and H, as the middle row faces a bulkhead and seats A and K have the door extending into their space.
The pitch for the majority of seats is 32 inches, but rows 26-30 and 42-51 offer only 31 inches. The centre rows 18-30 offer 33 inches, but those in the rear cabin are the standard 32 inches.
Power points (110 volts) are at seats A, D, F and H.
