Faced with a four-and-a-half hour layover at Detroit Metro Airport, I head to the Delta Sky Club. "Sir," the lounge agent says, a mild look of concern on her face, "do you know that there's another SkyLounge closer to your gate?" I do, but I've done my research and know that this one is bigger and has better food (thanks, LoungeBuddy). I'm sure the agent is just trying to be helpful—and that she knows that Americans are 'gate huggers,' travelers who, once through the TSA checkpoint, make a bee-line for their gate and stay, no matter the "dwell time" (as it's called in the industry), within a five-gate radius of their departure point.
