Depends on the equipment as to which airport one might fly from.

We cover all three metro airports with IAD being the main base.

777 only has schedule departures from IAD

757/767 is mainly IAD with maybe one a day from DCA and a couple per day from BWI (this is a wag)

320 is about 60% IAD, 25% DCA, 15% BWI (again an educated wag but close enough for the general idea)

It is extremely rare to be scheduled to begin from one airport and end at the other. If something screws up or you get reassigned, the company then has to crosstown(surface D/H) you back to your originating airport.
