The TSA is trying something novel at Denver International Airport: When you reach the security checkpoint, you can choose which line to enter--expert (travel frequently, know the rules), intermediate (not quite an expert, but it's not your first time at the rodeo), and beginner/people who need more time (families, special needs). In a cute touch, they're using traditional ski iconography--black diamond for expert, blue square for intermediate, green circle for beginner. Evidently, the system is working, just as it did during a trial run at Salt Lake City's airport. Thanks to The Travel Insider for pointing this out; he saw it in The Denver Post.
