I fly with
lots of former corporate guys at my airline. The main difference from others that came from a civilian background is that they tend to have been hired at a later age than their regional counterparts.
Conversely, I can't recall one leaving my current job for a corporate job. A few left for other majors over the years, for various reasons, but the voluntary attrition rate is very low, like less than 10 people in the last 20 years.
Like any job, corporate jobs can range from awesome to worse than the worst regional. The best ones, apparently, are the large ones that are run like, yep, you guessed it, an airline.
My experience in the corporate world was brief. I enjoyed what little flying I did, but, sitting around airports all day waiting for the passengers, living with a beeper, no set schedule, cleaning the airplane, arranging catering etc. etc. didn't suit my lazy pilot demeanor
, nor was I building much time for the majors. It was a good "in between" job. I know guys that love it though, so whatever floats your boat.
