For someone flying alone A and K seats are best. Normally I prefer the last row in the cabin (ie row 2) as being more private, but in this cabin the middle E & F seats are set back slightly behind the A & K seats.

I've now sat in all of 1A, 1K, 2A, 2K and really didn't notice a difference between them.

If flying with someone else the middle seats are best and I'd prefer 2EF.
