I use pvc pipe fitting on the rails and nose then wrap the entire thing in bubble wrap and have never had a ding. As far as bringing it thru security the only place I have been able to do that was SJO Costa Rica. When I was working the flight I kept my 6'0" in the cockpit of the bus but I don't know how well that would go with some crews. Most airlines will charge you for the boards even if you work there, pretty lame in my opinion.
