When you're running through the airport, weaving through a maze of people with your luggage, you can wind up in a frenzied and frazzled state by the time you reach security or reach your gate.
You can help smooth the process a bit by investing in a pouch that can hold your passport, plane tickets, ID, money, and anything else that is small and flat. These holders can go around your neck or around your waist. They're really handy for easy access to those essential papers that you'll need as you weave your way through the airport.
