Unstable job environment? I've been a corporate pilot 20+ years. 3 jobs. Flying the Global Express now. Depends who/what you know for sure. I laugh at these guys thinking the can easily "step down" to corporate.
It IS who you know but don't listen to these guys saying corporate is a bad idea. Most likely they are out of work airline pilots thinking they could parlay into corporate. Clearly they can not.
In my experience airline and military pilots have trouble making the transition to corporate.
Corporate jobs are awesome if you have the right attitude and yes, the right connections.
