On average first officers take home about 6'500 MYR per month after Tax... It is not much, but Air Asia picks up the type rating bill... which is nice!!!
As for the FAA licence... Malaysian DCA are in line with the British CAA, other words JAR. FAA licenses aren't favoured without hours of experience!!! You still gotta try, or you will never really know.
A bit of a tip from my days of job hunting... Ain't gonna hurt to ask!!!
GOOD LUCK and keep plugging away!
