They start around $50k, usually get a big bump around the fourth year when they get "captain qualified" (which is at company's discretion) to about $90k, and can top out after 18 years around $130k.

Of course, this being swa, there is significant opportunity for flexing your pay up depending on how much you want to work. If you work your butt off, you could probably make 50% more than whatever your longevity would otherwise get you.
