zerozero has very good points. Just to reinforce some of what he mentioned. Always, always, always, make sure you shut the rear doors, checking the seat belts and any baggage in the back is secure. Don't allow someone else to do it for you. Always follow the same routine as you move around the aircraft prior to getting aboard your self.
