Fly wherever you want to fly but make sure you make your decision NOT based on what the upgrade time is but how long the commute (hopefully none), and how great the work rules are.
If you live in STL, ORD, or RDU and love working for a company that literally doesn't care if you live or die....a career at TSH is for you.
Otherwise seek employment elsewhere.
Also don't let people on a forum do your decision making for you...you're a big boy.
EDIT: Also don't be one of those guys who says they work for "United Express" or are too shame to put where you work on Facebook. Have some damn pride in your job....if you work for GoJet it shows that you're a professional when you don't have to mask where you work. Jesus.
