I think EVERY passenger should acknowledge the work the flight crew member who made the effort to get off his rump to thank his passengers as they exit. I know I make an effort to do that - and feel like the "hired help" when our passengers don't look up as they walk off the plane.
I don't stop for conversation at that point because I know there are dozens of people behind me wanting to get off to make their connecting flight. I try to be respectful of them as well.
I've had a couple of instances where I was mistaken for a jumpseater. I quickly explain my status as a paying customer, and have never gotten anything from appreciation from the flight crew. Back when we were hiring, I also got my share of resumes!
I must also say, I have had more than my fair share of conversations with NetJet pilots all over the country. If there are jerks who work there, I haven't met them yet.
See you all in Teterboro!
