That's all well and good, but it doesn't seem to have been the case in this particular incident.
If you read the article it said:
The incident delayed the flight for 12 minutes, Wilson said.
"She kept saying, 'I was just kidding, can't you guys take a joke,' but it was something the airline took very, very seriously,'' Wilson said.
And yet the flight was only delayed 12 minutes? It doesn't sound like these pilots took any kind of sobriety test. The 12 minute delay was probably so they could take the woman's checked baggage off the plane.
Now obviously if you make a joke about a bomb or a gun or something like that, you're going to be pulled of the plane and most likely arrested. Yet not only was this woman not arrested, she was put on a later flight at no additional charge.
I'm talking about the pax who just wants to screw with you for whatever reason. He's pissed at your airline, or pilots in general, or the world in general. That type of pax doesnt get to fly with me. He gets to go later.
Why would he get to go later? If the person was truly a security risk he or she shouldn't be alowed to fly at all. Sorry, but your comments sound more like a case of someone who puts on a uniform and decides he gets to be a control freak on a power trip.
Was the woman's attempt at a joke tasteless and uncalled for? Yes. But was she really a security risk? I think not.
