Personally I try and sit in the flight deck when J/S possitioning, even if I don't know the flight crew. Guaranteed every time I need to possition from my home to my base the flight has 188 pax plus 50 screaming babies and the only seat left is seat B or E in between a flatulant 25 stone manatee and some lunatic plane spotter who asks questions for the entirity of the flight. For some reason the concept of pilots sitting on a plane and not flying it is completely absurd to most pax and they stare at you as if you've got antlers or something.
Survive all that and you get home and have nightmares about scratchcards.
