There would be no way of knowing for sure. For example, AS 6 and AS 5 (LAX-DCA / DCA-LAX) are sometimes operated by the same plane, and sometimes the plane that flies LAX-DCA goes on to Seattle. One other thing worth mentioning would be that AS is not currently operating nonstop LAX-IAD flights, so you would have to be prepared for the possibility that your flight is canceled and you are rerouted through SEA or put on the LAX-DCA flight.
