I'm a Netjets Pilot,
I flew on Pinnacle today home from MSP to CVG. I wasn't in uniform, but I still stuck my head in the cockpit and said hi. Mostly to let them know a CRJ typed pilot was in the back, but I also wanted to see how things were going there (I'm former Comair as well).
I can say that I usually will stick my head up front on Comair, sometimes on other "regional" airlines because I usually get bombed with questions. However I never do it while flying on a major. I don't know why, I just don't.
However, every time I deplane I thank the pilot for a safe flight. ALWAYS!
That's all
