stay at home and become a captain....
wanna see the world?
stay at home and become a captain, after 1500PIC on a 737 you can easily join as a DEC on 777/787 anywhere in S.E.A region.
Home + PIC 737 = Happiness.
Expat + DEC on 777/787 after your PIC 737 = Happiness .
FO 4 years(that's if you're lucky maybe much longer) + another 2-4 years as NB captain ... = ....?
