Please put your luggage by where you sit; not in front of the plane. I feel for the poor souls who have not boarded yet and wind up putting their luggage in the back. I know how the poor souls feel as this happens to me when first class upgrade is given after I've boarded and settled in my coach seat.
I don't like it when the flight crew put their carry-on in the section reserved for elite traveler.
Passengers seated behind you who will not let you deplane because they just have to get off. Wait your turn, please.
