There was nothing wrong with checkpoint security on 9/11. Given the single-percent positive comments on TSA news articles, I doubt the airlines would go bankrupt due to fallen traffic if security was being run by the private sector, with oversight by the DOT or FAA.

I can tell you first hand that my friends and relatives in Europe would start visiting the States again if the TSA went away, even more so if CPB quit acting like thugs. All in all I would expect a net increase in air travel. An interesting thing to ponder...
