Practical tips
Seattle and San Francisco are far apart, so a long overland journey can swallow a full day of your trip. Use the comparison table on this page to confirm that the flight fits your schedule and budget.
Check the airport codes before paying: SEA for Seattle-Tacoma and SFO for San Francisco International. The Bay Area has other airports, so confirm your arrival airport matches your hotel, hostel or onward plans.
From downtown Seattle, the Link light rail runs to the airport station, which is an easy walk from the terminal. It avoids traffic and works well with luggage, so you do not need a car.
At SFO, the BART station is connected to the airport, with trains heading into downtown San Francisco. It is usually the simplest budget option for the city transfer, with no need to rent a car or book a taxi.
Fares tend to be better when booked ahead. On the day, arrive early for security and bag drop, and prefer earlier departures so a delay will not make you miss a same-day onward connection.
The journey experience
Seattle to San Francisco is well over 600 miles, the kind of distance where the wrong choice can cost you a whole day of your trip. The option listed here is the flight, and it keeps you moving without a car. The comparison table on this page shows duration and price range at a glance, so you can decide in seconds.
Flights link Seattle-Tacoma International Airport (SEA) with San Francisco International Airport (SFO), and airlines such as Alaska Airlines and United serve this pair of airports. It is a simple airport-to-airport trip with departures spread through the day, so it is easier to rebook if your plans change. Standard US domestic rules apply for check-in, security and baggage, and travelling with only a carry-on is often the cheapest way to fly.
The main traps are choosing the wrong airport and arriving without a plan for getting into the city. Both airports are well connected to downtown by public transport, so you do not need a car or a pricey taxi. Note your terminal in advance, arrive early and keep your onward ride simple. Book ahead for the best fares and you will arrive relaxed and on time.

How long to visit San Francisco?
Plan 3 to 4 days to cover the essentials without rushing. In 3 days you can see the Golden Gate Bridge, Alcatraz (book weeks ahead), Fisherman's Wharf, Chinatown, the Mission and a cable car ride; a 4th or 5th day allows Muir Woods, Sausalito or a Napa/Sonoma day trip. Always pack layers, as fog and wind can make summer afternoons cold, and use Muni plus walking rather than renting a car in the city.
