Passengers are subject to much more extensive screening than in the past, including screening of checked baggage at check-in time, and, according to news reports pat downs that approach groping. Airlines recommend arriving at least an hour earlier than before. In my experience the extra delay is rarely more than 15 minutes, even with the extra baggage screening, although I usually fly out of smaller airports, not big hubs where you can get the killer two hour lines. The TSA has handed back screening at a surprising number of airports to private contractors, all of whom wear outfits intended to look like TSA uniforms. There is remarkable inconsistency in procedures from one airport to another, particularly with respect to your shoes, is worse than ever. Don't put your shoes in a bin, do put your shoes in a bin, and they all insist very loudly that whatever their rule is has always been the rule everywhere. A variety of extra cost "trusted traveller" plans may allow people to get through the screening faster, or may just involve waiting in a different line. The TSA makes no promises. If you don't want to go through the X-ray machines, whose safety is nowhere near as clear as the TSA would like you to believe, you can get a light body massage instead. They have a web site with estimated wait times based on averages in previous months, not real time numbers.
