I have just finished the sim/med/interview.
330 FO are paid 7000 US a month and that is after your insurance.
777 FO are paid 8000 and 747 are paid 9000. 737get 6200 or so.
You get 9 days off at home and you can add 2 vacation days to that.
I agree that if you just make a effort with the culture you will do fine.
