All fair and well Luke! That flying does seem like fun. The reality is that the likes of Vietnam Airlines will never look at an expat FO without experience. And to get that experience you'll probably have to "go airline" anyway beforehand.
The days of getting an ATR/A320 job by doing 2000 hours of Caravan flying and then a season or two of twin turbine time are history. ie the natural progression.
These days it's "must have Type Rating with hours on type or there's the door"!
PS: No doubt a particular person from a Certain Training Company
will be on here soon telling us in a two page essay, how good his organization is at placing cadets etc, but that's a whole different debate now. All in my humble opinion of course.
