There has been a gradual easing of some of the security measures applied to airline passengers after 9/11. In 2005, the TSA changed its policies to allow passengers to carry on airplanes small scissors, knitting needles, tweezers, nail clippers and up to four books of matches. And in September 2011, the TSA no longer required children 12 years old and under to remove their shoes at airport checkpoints. The agency recently issued new guidelines for travelers 75 and older so they can avoid removing shoes and light jackets when they go through airport security checkpoints.
