Exactly.
Not trying to diss anyone... but my experience on the "other side" of things has been a mix between folks who have a preconceived notion of what should happen when checking in a gun, whether because "they always do it (such and such) way at airport X" or they didn't follow the basic rules of packing it in their luggage: no ammo in the gun OR magazines and ammo ONLY in an ammo box, not loose (not even one round!)
A poor experience is more than likely the passenger's fault, as shown time and time again over 16 years of airport duty. Fly or don't fly, but be meticulous about packing a firearm for travel and you'll never go wrong.
