This seriously eats into my time on the ground, as does renting the car in BWI instead of VA, most of my friends and places to stay will be in VA.
If you want nonstops from PDX-WAS, then UA is currently your only option. There's one nonstop flight from PDX to IAD each way on United. DCA is essentially prohibited by the current perimeter rule out of that airport.
