M20EPilot Quote: Finally, maybe because I was indoctrinated in the old school way of things -- I always check in with the crew and introduce myself, asking the captain for the ride, even if given a seat in the back and 'listed' as a nonrev.

Great advice and great courtesy.

The only time I didn't personally request permission to board and thank the captain for a ride on a non rev was when he was CLEARLY too busy to take the time to talk to me (crap wx and pencil whipping an MEL). It only happened once, and I wrote a note saying that I didn't want to disturb him while he was so busy, but I wanted to thank him. I gave it to the FA to give to him. I have no idea what his response was (WX and a tight turn kept him busy at the destination), but I hope he appreciated the gesture.

Even when I was positive space on a company flight (we didn't do that much), I tried to at least say "hi" just to let the crew know in the case of emergency, they had a company pilot on board.

Maybe what I did was overkill, but I'd like to think I never snubbed a captain.

Short answer: If you are riding for free, be sure to thank the captain. One day when you are the guy signing for the plane, you will appreciate the gesture.
