non-secure means areas like ticketing level(outside security), baggage claim level, ground transport center, parking garages, light rail transit station and transit hub.
to idiot proof this: if you get in a line at the airport and you are carrying a firearm. chances are you are gonna be in the wrong. so don't carry if you are flying that day. please follow airline and federal regulations regarding the transport of a firearm aboard a plane.
I recommend ONLY carrying at the airport if you are picking someone up or dropping them off AND not escorting them through a federal security checkpoint. keep in mind that the air transportation sector is at threat level orange while the rest of the nation is at threat level yellow. be smart those are federal charges if you oops it at an airport.
