  • Looking for a cheap flight from San Francisco to Washington Dulles Airport? 25% of our users found flights on this route for San Francisco or less round-trip.
  • Washington is home to Ronald Reagan Washington National Airport (DCA), Baltimore/Washington International Thurgood Marshall Airport (BWI), and Dulles International Airport (IAD). Only IAD offers flights to San Francisco International Airport (SFO) among the three. Thus, you’ll have to head to IAD to board your flight to San Francisco.
  • The means of travel you use to travel to IAD will depend on how quickly you want to get to the airport and how much you can afford as fare. If you want to get to this airport quickly, you should catch a taxi, whereas if you’d like to travel economically to the airport, you should travel by bus. The metro trains that serve the station are a little slower than the taxis and a bit more expensive than the buses. As this is the case, if you’d like to balance the cost and speed of your journey to IAD, you should board a train.
