IAD is not slot controlled so any carrier that wishes to could fly there. I'm sure with Independence gone there (could) be a lot of open space just sitting there waiting for someone. ("I havent been to IAD recently so I cant comment for sure on that.)
DCA is slot controlled and I'm sure some of the carriers would be crying that US/UA had too many slots. Give up some and keep your flights where the money is from DCA. There isnt the stranglehold on the "entire" DC market like there was back in 2000.
