[George Smiley]

Airlines are private, subways are public.

But AIRPORTS are public.

And you get searched in the public airport, not on the private airplane.

[Stu Cohen]

And you get searched in the public airport

I don't. Unless I am preparing to board a private plane.

I go to the airport all the time without going through security. They even have a decent resturant there. I don't get searched unless I have a boarding pass and am proceeding to a gate. The gates are private property, leased by the individual airlines.
