Top tips for finding a cheap flight from Washington Dulles Airport to San Francisco

  • 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.
  • Before entering IAD, one must go through several security checkpoints. These checkpoints are usually characterized by long queues. Because of the queues, these checkpoints usually take a lot of time to clear. On numerous occasions, passengers have missed their flights at IAD after being unable to go through the airport’s security checkpoints in time. To avoid such a fate, on your departure date to SFO, you should reach IAD at least 1h 30min before your flight so that you have enough time to go through the checkpoints.
  • At SFO, if you’d like to charge your phone, you can do so at one of the power outlets spread across the airport for free. However, these outlets charge phones slowly. If you’re willing to pay a small fee to charge your phone quickly, you can visit the quick-charge stations near Gate 23 in Terminal 1, near Gate 61 in Terminal 2, and Gate 87 in Terminal 3.
  • If you require medical assistance while at SFO, visit the SFO Medical Clinic on the Boarding Area A side of the International Terminal. On Monday to Friday, it is normally open from 7 am to 7 pm, while on Saturdays, it is usually open from 9 am to 4 pm.
