I LOVE AIR JAPAN!!!
It's great if you don't mind being literally "fatigued" the whole time you are here in Japan, with constant, never-ending schedule changes. Never mind that pass rate for the upgrade program last year was barely 50% - mostly for bogus reasons. In general, with a few exceptions of course, your outcome is already decided before you even start the process.
The conditions and schedules haven't gotten any better yet - at least for me - just worse. Maybe due to lack of manpower or other reasons; who knows? Or the schedulers just don't like me. Every company has its positives and negatives. The reason some guys leave here is, well, because the negatives outweigh the positives for them. Good on those with more positives than negatives. Can't blame on anyone who is content with this place. What suits one person definitely won't suit the next - especially here. It ain't suiting me very well at the moment though.
Just my 2 cents, for what it's worth...
