Top tips for finding a cheap flight to San Francisco (SFO)

Hit the “buy” button in the Goldilocks Window

One of the many things we’ve learned over years of tracking airfare prices is that there’s a sweet spot for buying airline tickets when they tend to be at their cheapest. For domestic trips, it’s 1-3 months before a flight. For international trips, it’s 2-8 months ahead. We call this the Goldilocks Window.

Keep in mind, though, that if your travel plans fall during a peak season or over a holiday, or you have very specific days on which you need to fly, you should add a few months to the equation. Flexibility is key to most great airfare deals. In any case, try to finalize your bookings before the airlines do their last-minute price hikes at 21, 14, and 7 days before a flight.

Consider flying out of a different airport

If you’ve ever scanned the best deals on airfare and lamented that none of them were from your home airport, we’d like to tell you that those killer fares can sometimes be exactly what helps you save money on your next trip. There are surprisingly low fares that crop up all the time from both big and small airports, and the savings could be big enough that even the additional expense of getting to a different departure airport would still make your overall travel costs lower.

Since SFO is a United Airlines hub, you might find an especially low fare from another United hub—like Houston, Newark, or Chicago O’Hare. If the price is low enough, you can even add the cost of a flight from your home airport to the airport with the cheap fares, and you’d still come out ahead. For example, if you live in Knoxville and find prices high to SFO, consider booking a cheap flight from Knoxville to Chicago and then a separate round trip from Chicago San Francisco.

It’s always worth keeping an eye on where the super cheap tickets are—you just never know when you’ll find the deal of a lifetime.

Take off when it’s cheaper to fly

There aren’t days of the week when airfare is magically cheaper to buy, but there are certain departure times when flights are typically cheaper. The peak season of any destination is busy, and airlines raise prices accordingly. San Francisco’s peak season is summer (June-August), despite the area’s notoriously chilly and foggy summer weather. By planning your trip for the shoulder seasons or even the off-season, you can save quite a bit on airfare.

If you can only get time off in the summer, though, try to plan flights at the beginning of the season (first two weeks of June) or the end (last two weeks of August), when fares tend to be a little lower. And, regardless of what season you’re looking at, you can usually save money on flights by avoiding the busiest travel days (Fridays and Sundays) and flying on the generally cheaper days (Tuesdays, Wednesdays, and Saturdays).

Sign up for email fare alerts

Once you’ve got an itinerary idea or two, we recommend setting up fare alerts. These will send you an email when airfare for your itinerary drops into your target range, saving you hours of time constantly tracking the cost of flights—not to mention the money you’ll save when you book your tickets. Just keep in mind that if your travel plans are still flexible, you’ll need to set up a fare alert for each trip. Or you can sign up for a service, like Going, that tracks all fares for you and alerts you when it finds the best prices to anywhere.

San Francisco’s airport is second only to Los Angeles’ LAX on the list of California’s busiest airports. It’s a major hub airport for both United and Alaska, and a focus city for Southwest. There are 49 airlines serving SFO, and direct flights available from 84 airports around the United States.

For more details and information on traveling with other kinds of animals, check the California Department of Food and Agriculture’s website. You’ll also want to check the requirements for the particular airline you’re flying, as those can vary.
