I just took a flight DCA - ORD the other day. Stood in line maybe 5-6 minutes. I regularly get sub-10 minute trips through security at BWI.<p>I think people confuse airport congestion with security holdups. Carry-on x-rays have been mandated for a very long time (long before 9&#x2F;11). And people always had to walk one-at-a-time through the metal detectors. What&#x27;s happened over the last 25 years or so is a massive increase in air travel in the U.S., without a corresponding increase in airport capacity.
