Dulles, like Seattle has a tram. That can be surprising. The TSA at Seattle is notoriously LONG, however, both times in the last year that I have flown, that has not been the case. At Dulles, the TSA lines were efficient as well. The airport interior is well marked for getting around. I did note that the garbages were full in the Southwest and Alaska areas- as we were there 6 hours and had lots of time to notice nit-picky things that nobody else would care about :). It was convenient to have a "charging station" nearby the Alaska waiting area (right across from our gate). It had 3 ports, and I noticed that as soon as I unplugged mine, it was jumped right on. Suggestion- have Dulles add a few more for passengers who need to recharge phones. Great experience, thank you.

It's pricier to fly into Reagan (DCA), but if your destination is core DC area, it is well worth it. I used Ubers and Metro; no need to rent a car.

Be prepared Seattle is a mess as far as the overwhelming crowds when you land . The bus line to get your rental car is unbelievably long almost 100 people so be prepared once you arrive .
