Changing Terminal

Changing terminals at Dulles International Airport is straightforward thanks to the airport's efficient train system. After you arrive at your terminal, follow the signs to the Aerotrain, which connects all the terminals, but be sure to allow ample time to reach your gate. With a current traveler rating of 8/10, the convenience of the train makes the transfer process relatively hassle-free, though some passengers recommend planning ahead to account for travel time between gates.
