The flight from Tokyo to NYC was operated by American Airlines. The airplane had the least amount of legroom I have experienced on a long-haul flight. My knees pushed into the seat in front of me. The cabin was freezing cold, and despite several passengers mentioning this to the crew, they didn’t do anything about it
