UA has some pretty good ops out of IAD -- and since it's a mini hub there are probably more non-stops to places you want to go than what DL offered.
I like their product, too -- especially their business class to Europe; although if you're not top-tier you won't get access to it unless you opt for an upgradeable (higher) fare. Nonetheless, there are always great deals on UA out of IAD!
