re: #386 Alouette
I have flown on international flights in the far far rear of a jumbo jet, the next to last row. It may be the safest seat but it is sure not a smooth ride.
In a 777, the extra room can make up for it. Found the seats are wider in the last row, and there is extra leg room. It was too small to put 3 seats on the window sides, or to squeeze in another row, so there is some extra room.
