I'm still a rookie but I can tell you 2 big truths. Commuting and reserve sucks, so try to avoid both.
Go from there. ORD is our largest base, you can get it right out of training, no problem. And reserve should be 2 months or so.
About bonuses.... $7.5k if you have a type rating, otherwise nope. But you shouldn't make a choice based on a bonus in my opinion. Things like reputation, time to hold a line, etc.... That's what matters.
Now, if you are in your low 20's.....go to PSA!, sit and relax.
