Middle seat is more private...
Yup.
747, though it's the same seat.
Get 1A/K.
Ended up the automatic seats chosen for my friend and I were 1A and 1k so i left it as is.
I think it's best because its the furthest away from the galley and no one in front of you unlike the couple seats.
Then since cabin was half empty FA made us beds in the couple suites which were empty. So we had 4 seats to ourselfs/half a cabin.
On a side note, FCT ducks changed to black from yellow.
