Might honestly be the worst major airport in America. A badly designed mess of stairs and platforms. The trains leave you close to high numbers. Low numbered gates are screwed. Terrible security.
Washington Flyer bus is pretty quick way to get to the Metro....if you must use this damn airport instead of Regan, that is. $75 for a town car, BAH! Suck it. So I'm on a bus.
United terminal becomes a zoo at about 2pm. All the international flights begin arriving, and ppl connect to domestic flights. Terminal way too small to handle the large amount of pax
