Can you change terminals at DFW without leaving security?

You can get between DFW terminals outside of the secure area by riding the free Terminal Link shuttle bus that departs from outside each terminal. To travel between terminals inside the secure area, you can ride the Skylink light rail that runs in a clockwise and counter-clockwise direction departing every 2 minutes.



Yes, you can easily change terminals at Dallas/Fort Worth International Airport (DFW) without leaving security by using the Skylink train. Skylink is a free, high-speed light rail system that operates entirely inside the "sterile" (secure) area, connecting all five terminals (A, B, C, D, and E). In 2026, Skylink remains the most efficient way to navigate the massive airport, with trains arriving every two minutes and a maximum travel time of only nine minutes between the two farthest points. This allows 2026 travelers to explore dining and shopping options in other terminals—such as the high-end boutiques in Terminal D—during long layovers without having to clear TSA again. It is important to distinguish this from the Terminal Link shuttle, which operates outside of security (landside). If you accidentally exit the secure area, you will have to use Terminal Link and go back through the security checkpoint to reach your gate.
