As a jumpseater, either in the back or up front, is there anything "required" in terms of notifying the FA's?
I understand the courtesy aspect, and that you are a "guest" on the aircraft and should act accordingly, but I was once grilled by the lead FA because I did not check in with her while jumpseating to ORD (I took all the appropriate steps with the CA; he welcomed me aboard). I apologized and told the CA I was sorry for the mis-step - he said not to worry about it, that she was just old and bitter. So true...
