I flew on JAL in F in 1977 from Tokyo to Los Angeles. No sleeper seats in those days. They gave us a JAL robe and I stupidly chose the Japanese meal which I had to eat with chopsticks. For my tastebuds it was awful and I remember the desert tasted of plain sugar. I was too shy in those days to ask for a western meal.
The continental breakfast consisted of some stale croissants. It was really bad.
