SID PLATE just a bit of clarification the proper protocol to check with the captain to see if the jump seat is available, and not to say that one is riding the jumpseat. Then if the captain approves, then the jumpseater notifies the dispatcher as appropriate.
It is also protocol to wait unitl all passengers have taken their seats before taking an unoccupied one. With that being said, the forward galley area or in the jetway, if one is being used, is the proper place for a jumpseater to wait.
I am sure that you, along with RYANAIRPILOT are the jumpseat police or your flights when needed and ensure that your jumpseater(s) don't occupy any seats blocked off for CG purposes, the first row, last, or emergency exit rows, until all passengers have been seated.
