INSANELY spread out. Give yourself +30-40 minutes. Shuttle to tram to this weird elevatedbus on the Tarmac. I walked over 1.6 miles from door to plane.
If you need to ride one of the shuttle buses to immigration/customs, stay by the entry door for a swift exit. That'll help you in getting in front of the crowd in the passport check lines.
If you are in need for any type of limousine, car & shuttle to nd from Dulles airport, Reston Coach Transportation can help. We offer 24 hourairport transportation by luxury sedan, limo & Buses.
Security here is a well coordinated ballet, but there's a large mix of nationalities, which make for long wait times during rush hours. Be smart and arrive early.
Five Guys has the best cheeseburgers. There's two locations: one in Terminal A and one in Terminal B. If you plan to have fries, you're better off with a single patty.
If you have a long layover go to the air and space museum. 12 minute shuttle ride from airport 1 USD round trip and soooo much more interesting than staring at a billboard
Those mobile homes on wheels that are driving around the airport are known as plane mates or mobile lounges. To me, they're known as a pain in the ass.
Parking is pretty convenient but cab to DC is pricey. TSA lines can get long but never spend more than 30 mins in them. Although I have had spent hours in immigration check lines many times. :(
