I have a friend there who is about to leave. After a reasonably happy start, things have gone steadily downhill. Hotac quality is sliding, and per diems have all but disappeared. With the slide in the US dollar added to this, the remaining package is unattractive to say the least.
I gather that a shortage of pilots renders leave difficult/impossible to get. Things are unlikely to improve, since the pending exodus will only aggravate an already bad situation.
Caveat emptor!
