I was Px'ing on a pax flight the other day, I was sound asleep only to be rudely poked in the arm and woken by a CC because my seat was not upright. When I moved the seat it moved just under 2 inches! iRobots!
On the Freighter you don't have the joys of that or of the CC storming up to you and demanding you turn your iPad off at 19,999ft!
