Cheap Flights from Seattle to San Francisco

Covering just 121.4 km land miles, it's hard to imagine how over 870,000 people live in San Francisco. It's easy, however, to understand why over 25 million tourists from across the globe visit San Francisco on an annual basis. From the iconic Golden Gate Bridge and cultural events galore, to cable car tours and the incredible LGBT community, San Francisco offers acceptance and adventure for all.

Arriving at San Francisco International Airport (SFO)

Passengers flying in from Seattle land at San Francisco International Airport (SFO), the busiest airport in northern California. Four terminals serve over 53 million passengers via 450,000 annual flights. SFO represents over 50 airlines, but United is the most popular option that flies in from Seattle. Amenities include free WIFI, an aquarium in T1, children's play areas in T2 and T3, a reading room, a museum, spa, and yoga room. SFO also has a special "Wag Brigade" that utilizes over 20 trained, pet-ready pooches to help de-stress passengers.

Sleeping benches are available in SFO, but they're not particularly comfortable. Fortunately, several local hotels offer their guests free shuttles to and from the airport. Bus service can be found at all terminals besides T1. The Bay Area Rapid Transit Rapid Rail (BART) is located at the International Terminal and offers a 40-minute ride to downtown. Taxis outside each baggage claim can shave ten minutes off the trip. But if you want to drive around yourself, offsite car rental agencies can be accessed at the airport's Rental Car Center.

Things to Do in San Francisco

Begin your adventure by walking across The Golden Gate Bridge, the most iconic bridge in the world. Spend $7 for a unique and exhilarating tour of the city via cable car. Kids of all ages will love the 600 hands-on exhibits found in the Exploratorium. Get an intimate introduction to San Francisco at Union Square Park. Looking for some serious nightlife fun? Head to The Castro, the heart of the LGBT community and what many consider to be the gay capital of the world. Take a tour of Alcatraz and be sure to get plenty of pictures. Appease your appetite at the Ferry Building Marketplace, a foodies paradise.

San Francisco Travel Tips

Summer is peak tourist season as hordes of sun-loving travelers hit the bay in search of sand, sun, and summertime fun. Spring can get quite damp, although April is consistently the city's sunniest month. Autumn is the best time to travel as the season combines some of the warmest days of the year with jewel-toned nature presentations that simply can't be ignored. If you opt for winter travel, dress in layers because San Francisco can get chilly. Whichever season you choose, trust Skyscanner to help you plan an affordable escape.
