It just looked it up and it happens that United has one flight per day from DCA to SFO and from DCA to DEN. I plan to start using that instead but it won't make a dent at IAD. I wonder how many takeoff/landing slots United has at DCA?
The problem isn't the total number of slots United has at DCA; it's the special restrictions on flights beyond a certain distance.
