China Airlines by far. For all the horror stories you hear about China, at least you are paid well.
What used to be a great job, has fast turned into one of the worst around.
Conditions eroded, min rest turn arounds nearly everywhere, staff travel expensive (full fare cheaper on some routes).
Failure rate amongst Ex Pats over 50% on some fleets.
Oh and non ICAO state, so your licence is not recognised anywhere else in the world.
