Схема салона Boeing 777-300ER (77W) v4 Saudi Arabian Airlines

Excellent seat. There is a large protrusion from the exit door, but it is far enough in front that it causes no issues. I am 6'3 and could fully stretch my legs. There is a window at this seat as well. You can get up whenever you want without disturbing your neighbours. The toilet is nearby, but it is facing away from these seats, so not a problem. Saudia's seats are a little bit larger and more comfortable than most, and the service and food is a bit better as well.

Avoid 47 c & j - these seats are significantly narrower than others in row 47 (and the rest of the plane) due to the toilets

I had no problems with noise from the galley or the lavatories, but the seat was not all that comfortable for sleeping (it was excellent for sitting and reclining). I think the discomfort came from a dip where the seat curves to match a person's back in seated position. The service on the flight was excellent, as was the food.

I sat in 55A and I must say I went in expecting the worst flying CDG to RUH but the seats were nice with decent recline and plenty of foot space. Plenty of movies (women legs were blurred), and food served with actual silverware. Of course after flying AF on a 773 with 10 abreast then flying a 773 with 9 abreast you enjoy the extra inch, plus the aircraft was only about 70% filled so there was an empty seat next to me. Only issue i had was that i was not able to really capitalize on the extra space like i wanted to because you cant lift the arm rest.
