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

Book in the Goldilocks Window

Over the years, we’ve found that 1-3 months before a domestic flight and 2-8 months before an international flight is when we find the best deals. We call this the Goldilocks WIndow because it’s not too early before a flight and not too late. Prices can be high when flights are first released (the airlines know anyone booking almost a full year in advance probably has set dates and is willing to pay a premium for them), and then prices tend to rise as flights get close, especially at the 21-day, 14-day, and 7-day points.

This Goldilocks Window isn’t a hard and fast rule, though. If you plan to travel during the summer, over Christmas, or other popular travel times, start looking even earlier. We recommend looking in July for a December trip and in December and January for summer vacations.

Use the Greek Islands Trick

Want to fly from San Francisco to the Greek Islands but see flights for upwards of $1,000? Try this trick. Instead, look at flights to London, Paris, or anywhere that gets you close to your final destination. Then, book a cheap flight within Europe for the last leg.

Of course, the Greek Islands Trickworks for all sorts of destinations, not only the Greek Islands. And depending on where you’re going, that last leg could be taken by ferry, train, or rental car. Budget airlines in Europe and Asia, for example, can have some incredibly cheap rates.

Cast a wider net for departure airports

If you live in San Francisco, you probably regularly search for flights out of Oakland or Sacramento. But what about LA? Or, hear us out, New York? It might sound unreasonable to look for flights out of faraway cities like Phoenix, Chicago, or Miami, but sometimes airlines offer too good-to-be-true deals from airports nationwide. Keep an eye out, and in those cases, consider whether taking a domestic flight to that airport is worth it.

We’ve seen deals like $63 from Atlanta to Chile roundtrip. Or $202 from Los Angeles to Japan. For those kinds of deals, even if you add a $100 flight from San Francisco to LA, you still save.

Fly when fares are lower

San Francisco follows most of the world with its travel trends. Summer and December are two of the most expensive times to travel into and out of SFO because that’s when everybody else is traveling, too. If you can, try to fly during shoulder season—the time between peak and low travel times. If you’re going to the Greek Islands, for example, the water is still warm in September, but many of the tourists are gone. Better yet, travel in the low season and see places in a new light, with few crowds.

If you have to travel during peak season, at least try to fly on Tuesday, Wednesday, and Saturday. These are the cheapest days to fly. No surprise, Friday and Sunday are usually the most expensive days.

Sign up for fare alerts

Set flight alerts to get price changes sent directly to your inbox. You can do this for a specific flight on Google Flights or for any destination with Going. This way, you can track prices without doing much work at all and pounce when a flight drops into a range you’re willing to pay. We recommend setting these up at least a few months before you plan to travel to score the best deals.

San Francisco is a major hub for United Airlines and Alaska Airlines, plus offers flights from 47 other airlines. There are hundreds of nonstop flights per day to 70 destinations around the US, plus dozens of international routes. If flying from SFO, you can reach much of the world with just one stop or less.

How early should I arrive to San Francisco International Airport (SFO) before my flight?

SFO suggests checking with your airline for how early you should arrive, but notes that most airlines suggest arriving two hours early for a domestic flight and three hours before an international flight. Whether you need to follow those guidelines depends on several things.

How big is the airport, and where is your gate? SFO is fairly large, and if you need to take the AirTrain to your terminal, you’ll want a few extra minutes. Similarly, if you’re arriving via the BART, add a few extra minutes to walk from the station to your terminal.

Are you checked in? Most airlines cut off check-in 30-60 minutes before the flight is scheduled to depart. Check in online to save time, but if you can’t, make sure you arrive before the cutoff.

Are you checking luggage? Similarly, airlines institute cutoff times where you can no longer check luggage. That’s usually 45-60 minutes before departure. Make sure you arrive before this time if you plan to check a bag, otherwise, you’ll be forced to find a different flight or leave your luggage behind.

How busy is the airport? On an average day, the security wait at San Francisco International Airport is about 16 minutes. That’s not bad for a busy airport, but if you’re traveling during peak times like winter holidays or summer, it can be longer. The same goes for weekend travel.

We recommend arriving at SFO at least one hour before your flight, but 1.5-2 hours gives you more leeway and a more relaxed travel day.

How far is San Francisco International Airport (SFO) from downtown San Francisco?

San Francisco International Airport (SFO) is about 15 miles from downtown San Francisco, depending on where in the city you’re departing from.

What are the different transportation options for going from the city center to San Francisco International Airport (SFO)?

There are several options for traveling from San Francisco to SFO.

By taxi or ride share: Downtown San Francisco is less than 20 miles from the airport, and you can get there by car in about 30 minutes with light traffic. That said, San Francisco traffic can be bad, and we suggest allowing at least 45 minutes to be safe. Costs range from about $40-60, depending on demand.

By public transportation: The BART trains connect downtown San Francisco with SFO’s International Terminal in about 35 minutes. From there, you can take the SFO AirTrain to other terminals. The cost varies depending on exactly where you’re coming from but should be around $10.
