Have you ever been in an airport AND in a hurry? Did it seem like everyone in the entire airport was following the same path as you?
Did you know there may be shortcuts in airports to get from one hallway or one point to another? How do you find them?
Take a good look at the airport concourse map. It shows all the hallways, the elevators, etc. You may just find a better way then following along after every other traveler.
