While not a physical item, this item can be biggest tool in your carryon. Who here loathes the TSA security line? I know I do and after years of suffering (yes Denver I am looking at you) having TSA PreCheck has changed the way that I travel. The signup process is fairly straight forward and its good for 5 years before you have to renew. The perks include* having a designated line (in some airports entire security sections), not having to unpack your carryon, keeping your shoes and a light jacket on, and in several airports a quick walk through the metal detector. All the little things that add up to a quick and smooth navigation of security so you can get your trip started.
*TSA precheck procedure may vary between different airports
