There are many enjoyable things about traveling, but waiting in line at the airport isn't one of them. Skip long security and customs lines at the airport or border crossing by enrolling in a Trusted Traveler program from the Department of Homeland Security. This includes TSA PreCheck for travel within the U.S. and U.S. territories by air, as well as Global Entry for travel into the U.S. from abroad. Keep in mind, each of the five programs has a different enrollment fee, but all come with a five-year membership.
