I can assure you it isn't just the Americans who haven't returned. Australians, Kiwis, Brits and the list goes on. You will be treated like a second class citizen, spend 19 nights of the month in a Japanese hotel. The per diem's won't cover your meals. The constant yo-yo between Narita and Haneda hotels. Not to mention that business class commute that you pay $2k for is a duty travel ticket (treated like again a second class citizen). Some have even been told at check in that there isn't a business seat for them. Before covid nobody left for EK. The fact that 90 hours a month living in Dubai is a better option than this place surely says something.
