You will find yourself flying with a local SIA F/O who will be paid higher than you as a cargo commander, and will fly First class when he is positioned to a point in the network, while you will sit with bend knees in a very full economy seat. If that is what you want, and you are able to live on 12000 Sin dollar a month all included go right ahead and join the cargo division. Don't forget though that you have to pay international schooling fees, housing fees and shopping fees, which will put one hell of a dent in your budget.
