Pros:

Rent where I am is $175/mo, no lease, not including utilities
Real world flying experience
It's fun
There's a lot of great people here (and a few not so great)

Cons:

I get paid $9/hr
I have no senority
The health benefits aren't great and are expensive...especially on FO pay
I'm not in the union
No upgrade for me for another year and a half (and then it's only more prop time)

My last day is next week. I was offered a job elsewhere. Yes I like it here, and it will be bittersweet. Definitely a great fall-back option, but at my age, I want to get paid more and get on a senority list with a jet (for career reasons).
