Overall Dulles seemed a pleasant enough airport to spend several hours waiting for connecting flights. The worst experience at Dulles was waiting in the overcrowded terminal for a connecting flight to Syracuse. There were too many flights leaving at similar times such that the seats were completely full with people standing and sitting on the floor crowding the walkways. Meanwhile many of the flights must have been overbooked as the desk people were frequently asking for people to offer to take later flights. The environment was so noisy and crowded that I ended up waiting in another terminal waiting until just before my flight's departure to head back to the area.
