Dallas/Fort Worth International Airport has five terminals and 182 gates. DFW's terminals are designed to minimize the distance between a passenger's car and airplane, and to reduce traffic around terminals. A consequence of this layout is that connecting passengers have to walk extremely long distances between gates, as there are no shortcuts or moving walkways between the ends of the semicircular terminals. The Skylink connects all five terminals inside the secured area. Terminal Link connects all terminals with a shuttle bus system on the non-secure side. All non-precleared international flights are processed in Terminal D. All non-American domestic carriers and pre-cleared flights from Canada use Terminal E.
