Are you old enough to remember what it was like to fly pre-9/11? If anything the TSA made things more difficult for airports who were hemorrhaging revenue despite whatever magic safety rays you feel the TSA was projecting into the populace. (What are the properties of these safety rays and why even years after they began eminating did we still see airlines in bankruptcy, flights canceled, and dependence on federal loans? If in fact they were meant to increase passenger counts they didn't seem to do a good job, and just look like an unexpected added cost to contend with along with declining income -- some lost income directly due to security measures like preventing non-travelers from giving business to any shops beyond the security checkpoint. Liquids weren't even banned for years, after a slew of attempted liquid explosion attempts, almost like the TSA is an entirely reactive force ever since its creation.) On the more tangible side of things the airports had to pay the costs of the new security measures, which weren't trivial -- e.g. just the explosives detection systems for checked baggage cost billions to be rolled out. How much for the body scanners some years later?
