Speaking of gates, have you ever tried to find your way through the Domestic Terminal? It's like navigating a maze - except instead of cheese at the end, you get to find your gate and collapse into your seat. With seven concourses to choose from, you'll be doing a lot of walking (see: calorie-burning) to get to your flight.
But hey, at least the People Mover is there to save the day (and your feet). This magical train will whisk you away to your gate in no time - or at least, that's the theory. In reality, you'll probably be stuck in a tunnel with a bunch of other frazzled travelers, wondering where your gate is and why you didn't just walk instead.
