Been around for awhile. Most people I speak to are not aware that the terminal is off limits.
F.S.790.06(12)No license issued pursuant to this section shall authorize any person to carry a concealed weapon or firearm........ inside the passenger terminal and sterile area of any airport, provided that no person shall be prohibited from carrying any legal firearm into the terminal, which firearm is encased for shipment for purposes of checking such firearm as baggage to be lawfully transported on any aircraft; or any place where the carrying of firearms is prohibited by federal law.
