I didnt flt at Centurion however since no one from there has sounded off:
I ran into the Centurion guys in South America and in a few bars in Miami a lot. They where nice guys and some seemed happy since they where based where they are based where they lived. However the money was abysmal and they dont seem that secure with a lot of rumors going around about huge cut backs one week and the next huge expansions. I think its fairly typical of Miami base carriers.
My thoughts are if you dont need a career place, and certainly dont need the money its a good place.
Best of Luck!
PS: also look at AmeriJets they do all day trips on 72's
