Things is Asia in general are not all that they seem these days. Have a look at an airline in the Fragrant Harbor. Once known as the premier airline pilot job in the world, most are clamoring to move on. Flying a B747 around the world in a foreign land is phenomenal when you are out of work at home, but once home calls again, there is nothing better than a job at a US legacy.
Having your schedule dictated to you and being gone 7-10+ days at a time is a grand adventure in the beginning, but it can where on you mentally and definitely physically as time goes by.
