| As some other commenters have noted, Dulles was designed for a different model of operations than most subsequent airports, and the efforts to integrate the design of the airport with current practices can be very awkward. Dulles is a distinctive airport in many ways, so much so that it presents significantly different experiences, based on the particular type of flight you're on, as I'll elaborate on below. For the aspects of travel that are universal regardless of type of flight (check-in, security, parking, etc.), it's decent overall. The new(-ish) train is a big improvement on the old "mobile lounges" (which are still used to concourse D, though), I've had mostly pleasant and efficient experiences with check-in, and have even been pleasantly surprised by the speed at security on some occasions. For getting to the airport via car, you definitely need to be aware of traffic and plan travel times accordingly - I've had many painless experiences, but if it's around rush hour, beltway traffic can be ghastly (though the Dulles Access Road itself is usually fine). For domestic flights, Dulles has the best selection of non-stop long-haul flights of the 3 DC-area airports, and it's generally an acceptable experience, concourse A/B is a lot nicer than C/D, though. For myself, if it's a choice between a non-stop from Dulles or a flight with a connection from another airport, I'll take the non-stop from Dulles; if the choice of flight is otherwise equivalent, though, both BWI and DCA are more pleasant options. For departing international flights, the experience is essentially like that for domestic flights - not great, but not bad either. For arriving international flights with Dulles as the final destination, it's below average. The mobile lounges to get to immigration & customs are always inconvenient and almost invariably crowded. I've had both good and bad experiences with the speed of immigration and customs, but the wait for luggage is usually short (if immigration is slow, there might be no wait at all). Since Dulles has the vast majority of international flights of the DC-area airports, if DC is one's point of origin/destination, there usually isn't a choice about which airport to arrive at. For arriving international flights when DC is NOT the final destination, avoid Dulles at (almost) any cost. The slowness and inconvenience of the mobile lounges, unpredictable time for immigration/customs, and the possible need to then take another train/bus to get to the concourse for your connecting flight must be incredibly stressful. To summarize: Dulles is acceptable for domestic flights and international departures, below-average for international arrivals with Dulles as final destination, and to be avoided if at all possible for international arrivals with subsequent connections.
