You can scratch HMY off the list, they're already gone. CanJet, very, very unstable. Zoom, again, a private owner and seems to be regressing with any expansion plans. SkyService, very strange hiring policy and actually laid off a few crews recently. SunWing, I'm hearing good things, but still young and unproven. TransAt, great airline, but you have to be bilingual.
Basically, you got AC and WestJet, if you're looking for stability. Neither company makes it easy for you during the first two years of service.
WestJet: year 1 - $40,000 CAD
year 2 - $45,000 CAD
year 3 - $75,000 CAD
Air Canada: year 1 - $38,000 CAD
year 2 - $43,000 CAD
year 3 - formula pay
Of course, these are approximate numbers, I don't work for either one of them and know these numbers through hearsay. The way I see it, AC will eventually pay out bigger in the long run but WestJet will give you a better lifestyle, especially when the port system works out (my opinion, of course).
The pay is fustrating which is why the original thread caused such a stir with Canadian expats. Overseas work is a small sacrifice to make for the pay and benefits to be made.
What ever you decide hope it works out for you.
Good Luck!
