Here are a couple of examples: The first leg of my African trip was via Jet Blue from Portland, Maine, to JFK, just outside of New York City. (JFK and Atlanta are the East Coast departure points for all Africa-bound flights.) At Portland, I declared my gun, and the Nice Jet Blue Lady called over a TSA officer to see that it was unloaded, as is standard. At some airports, not all, the TSA also checks for hidden explosives, and to do this they look at the case, not the gun. So the Nice Jet Blue Lady told me to leave the case unlocked and give it to her so that she could give it to the TSA bomb-checkers.
