2/3 of my department are ex 121 pilots including myself. It may be true in some places that 121 guys are blackballed, but I know for a fact there are flight departments (including my current) that have ex-airline guys and would prefer hiring ex-airline guys in the future. My personal opinion is I'd rather find a 121 guy with the right work ethic and personality. The corporate side of the business can be easily learned and if they have done any real 121 flying, they can fly an airplane. I've seen guys with purely 91 backgrounds who fly like crap and don't have any real training because they've never been through a 121 program. Say what you want about FSI and CAE Simuflite but anybody who has done both knows that airline training is FAR superior.
