Wynsock,
understand your frustration but even this one is far beyond DOTARS influence. I don't believe there would be an airline in the world where non-crew personnel are allowed up front any more. Pretty sad really because it is those visits that I am sure inspired may young kids to pursue the ultimate dream.
I believe it was last week that a woman was arrested in Malaysia after she had a spit at the cabin crew for not allowing her obnoxious kid into the flight deck. Use of the magic word "hijack" was all that was needed for Mr plod to be waiting at the gate for her.
