Sydney to Tokyo then on to Vancouver and Mexico City. The economy seats are not made for people over 6 feet and I would never fly JAL again. The bulkhead seat has neither room to stretch your legs out, nor put them under your seat. Absolute agony. The bulkhead seats are so narrow that for fatter people it would be impossible to fit into them.

Seat pitch is on the tight side for anyone over 5'8" tall, about 31". Anything over 4-5 hours in this it will become uncomfortable. Seat comfort and width itself is otherwise ok and comparable to typical economy class seat. Being a 767 the layout is 2x3x2 means anyone is never more than 1 seat away from the aisle.

Tokyo Narita to Bangkok operated by Jalways Airline, a subsidiary of Japan Airlines. Seats were relatively new, but cramped both in pitch (about 30"-31") and width. Seatback video.

I felt uncomfortable with this seat. Seat is made of hard material. And seat pitch is only 31 inches. Quite lucky that an economy class seat in B767-300 has a headrest and a footrest. JAL improving their IFE. However, I hope they focus more on improving their seat comfort, especially seat pitch.
