Washington Dc Airport
I thought I was the only idiot who didn't know the name of the tunnel you have to walk through to get to the plane.
Guess what when I went to search to find out what it's called and one of the search results on Google was exactly that: "What do you call the tunnel you have to walk through to get on the airplane?"
I'm thinking about calling it airplane walkway. But according to Wikipedia it's called a Jet Bridge, a movable connector which most commonly extends from the airport to the plane.
There you have it... That thing is called a Jet Plane, no... a Jet Bridge.
