We wrote about this a little while back and it’s proving to be an incredible time-saver. The TSA’s new “Pre” program allows you to use a special line at many of the country’s airports that eliminates much of the aggravation. If you’re approved (it’s just a simple background check for criminal activity), say goodbye to taking your laptop out of your carry-on, taking your shoes, belt and coat off and other post-9/11 annoyances. The application process is quick and simple and the service is well worth the $85 processing fee. There’s also Clear, a subscription service that lets you skip lines at eight airports around the country for $15 a month.
