Only try to purchase duty free stuff from the terminal you're departing from. Also - five guys at terminal B and there are smoking lounges after security.
Hit and miss on the terminals. The international terminal is very nice. However most are small dingy and crowded. Pay close attention to the Train and bus routes.
Premium/Fart track does not always apply, prepare to stand in line for a good hour for security even when traveling business and top tier loyalty member.
Dulles is located at 1 Saarinen Circle, named for it's architect, Eero Saarinen. If you stop by DAG you'll see several pieces designed or inspired by Saarinen like our "Conversation Pit."
needs a priority lane for passengers with connecting flights when entering here from an international flight to make a connection within a couple of hours
Not impressed with the airport. Very few shops stay open 24hours so if you have an overnight flight, you're screwed. There are charging stations which is a plus, but definitively not enough.
Be VERY careful if you have a close connection late at night here coming from out of country. They seem ill-equipped to deal both at Immigration and TSA. Almost missed my flight w/ 1.5 hrs.
