TSA security loophole exploited

As this blog has reported on multiple prior occasions (in 2006, 2008, and 2009, at the very least), the fact that U.S. airport security separates the checking of the boarding pass by TSA from the use of a boarding pass to check in to board makes it easy to get through security with a boarding pass that matches your ID while flying under a boarding pass on a ticket purchased in a different name.

Now, as The Economist (July 2, 2011) reports, Olajide Oluwaseun Noibi, a 24-year-old Nigerian American, has been arrested after successfully doing something along these lines to fly around the country, apparently on multiple occasions.  Only Noibi wasn't even using boarding passes valid for the flights he was on--he was caught with a boarding pass in another person's name for a flight from a day prior.  And he wasn't caught because the boarding pass was detected at check-in--he had already successfully boarded the flight and was seated.  He was only caught because of his extreme body odor and a fellow passenger complained, which led to his boarding pass being checked and found to be invalid.
