Hello there 767-300ER,
I've flown on this plane only 3 times... On American from SFO-MIA, and on United from SFO-CDG and ZRH-IAD. I think that the plane is very comfy, and it was great on American cause I got to sit in the bulkhead seat! On United, the planes were the same except I thought the seats were better, but today all the United 767-300ERs have the new seats and seatback videos, the best in the business baby! However, I don't think that any 767 can be as good as the 777 or 747!
