Top tips for finding a cheap flight from Washington, D.C. to San Francisco

  • Looking for a cheap flight? 25% of our users found flights on this route for ₹ 18,597 or less one-way.
  • 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.

dont re-route to San Jose. Re-route to closer airport. Provide shuttle bus to go to SFO, not just LYFT vouchers.

WiFi connection bad. Food is really awful. Crew very nice and efficient

It was the worst experience because they delayed the flight by 2 and half hours. We were supposed to depart by 3:41 but they did the depart by 6 pm. It was so boring!!

This was a short flight with many open seats. Overhead space is limited and there are no screens in the seat back. But overall the flight was comfortable and fast.

Poor experience. 4 hour delay. 2 hours because of weather and runway construction at SFO. But gate logistics were a mess (gate was used by an unsigned flight to SAN first (!) ... lots of time spent weight balancing the flight because of an inoperable baggage hold (initial loading should have taken that into account, since plane had been flying that way that day) ... and then plane had to go back to gate for more fuel because of SFO delays (easily could have been done - and foreseen - while reweighting the plane). Airline came across as extremely disorganized. Note: on-board experience was fine ...

I think in 6:15 hrs flight the airlines should give some meal and not just couple of cookies People reach their homes at around 12 mid night and then they have to make dinner and eat I started my home at around 5 o clock and no food till 12 midnight You should give some reasonable meal in flight Thanks

The only options for beverages were water and apple juice. When did that happen?

Pretty terrible. The aisles on this flight were too narrow so we had to carry our baby, care seat, luggage, travel stroller step by step down the aisle slowing down a lot of passengers in the process. Not only was this a safety hazard but remember that scene from game of thrones where Cersei walks naked through the streets? It felt about as excruciating as that except both me and my husband were carrying 50lbs of weight while everyone from the flight attendants and passengers dolled out comments like “that stroller doesn’t fit in the overhead compartment and you should check it at the gate” when it is a travel stroller that absolutely fits and did fit in the overhead compartment. The flight said it was 30 min delayed but in actuality we did not take off until 1.5 hours past the original time. It was absolutely terrible. Alaska also charged us 200 dollars just in baggage fees even tho we took the time to buy two check on baggages via their app and bought an extra seat for our child and they still refused to overlook our first time flying with them. Everyone in general looked super miserable and traveling with them with a child is pretty much untenable. Lastly I originally thought I had booked an AM flight for my family but it was a PM flight which I knew was not going to end well since we had a 1.5 year old with us on a flight that gets in 9p. I ended up calling Alaska to try to change the first leg for a change fee, and would even have accepted half of a refund to book a completely different flight but of course they refused and absolutely allowed no flexibility to plans so I guess my revenge was our baby cried for 3 out of the four hour flight and hopefully convinced every miserable person on that flight to never fly Alaska again 🤷🏻‍♀️

watching out the window as the loaders bounced the luggage onto the carts as it was deplaned made me understand why some of my bags have been destroyed on the airline.

Great no problems. Very friendly. An hour ahead of schedule

Overall the flights pretty good. The snacks we’re good and they were plenty of them. Both boarding and deplaning went quickly.

Delayed abs delayed Gate crew giving poor info - we are definitely leaving at —- Ultimately to cancel flight after 4+ hours of delays Just cancel it earlier

The flight was scheduled to depart DCA at 12:30 pm but was delayed twice on the ground so that we were finally scheduled to depart at around 4:00 pm. Once we boarded, it was announced that takeoff would be delayed again to fix a hydraulic problem which delayed our eventual takeoff until around 5:00 pm. Once we departed, it was a smooth flight back to ORD. We did not get any explanation about what caused the original significant delay. In my experience, this happens frequently with AA.

Plane was good but was delayed. probably not AA fault but caused a 1 hour delay. Seating was cramped.

The staff were very helpful with lots of refreshments on offer. The toilets were clean. The seats were comfortable and entertainment was good. No complaints, it was excellent.

Lots of weather delays that were poorly communicated and managed. I get there are weather delays but they didn’t make it clear what was happening or comfortable on the plane

Everything was on time; the flight attendants and the gate personnel were very pleasant and helpful.

Our second leg to Jackson WY was unable to land due to weather. We were flown back to Dallas after stopping in SLC. We were given hotel rooms and vouchers. We were told that we would be back on the same plane in the morning. Instead we were given a different flight with different seats. Not a good experience. No one knew what was going on.

Perfect flight. On time departure and early arrival. Smooth flight.

Plane felt so crowded and tightly packed. The chair itself was not comfortable.
