SFO San Francisco Airport Guide

Flying through SFO has gotten complicated with all the conflicting advice flying around. I’ve been through San Francisco International more times than I can count at this point, and every trip teaches me something new. Last fall I nearly missed a connecting flight because I underestimated how far Terminal 1 is from the International Terminal. Lesson learned the hard way.

Probably should have led with this: SFO sits about 13 miles south of downtown San Francisco and handles millions of passengers a year. It’s one of California’s biggest airports, and honestly, once you get the layout down, it’s not that bad to navigate. But that first time? Yeah, give yourself extra time.

Getting the Terminal Layout Straight

There are four terminals at SFO. Terminal 1, which they renamed the Harvey Milk Terminal 1 after some solid renovations, handles a bunch of domestic carriers. Terminal 2 is where you’ll find American Airlines primarily. Terminal 3 is United Airlines territory — if you fly United a lot, you’ll get to know that terminal well. And then there’s the International Terminal, which is exactly what it sounds like. All your overseas flights go through there.

I remember being confused my first time because the terminals aren’t always in a straight line the way you’d expect. The signage is decent, but I’d still recommend pulling up a map on your phone before you land.

How to Get There (and Back)

One thing I genuinely appreciate about SFO is the transit options. BART connects directly to the airport — the station is in the International Terminal — and that’s probably the easiest way to get downtown without dealing with traffic on the 101. I’ve taken it dozens of times. It’s not glamorous, but it works.

SamTrans buses run to various spots in San Mateo County and even up into San Francisco proper. Uber and Lyft both have designated pickup areas at every terminal, which they reorganized a couple years back. Honestly, those pickup zones used to be a mess, but they’ve gotten better about it. Taxis are still an option too, with stands at each terminal. Old school but reliable.

If you’re renting a car, all the major companies are at the Rental Car Center. You get there via the AirTrain Blue Line, which is a short ride. And various shuttle services run to nearby hotels if you’ve got an early morning flight and want to stay close.

Parking at SFO

Parking. Nobody’s favorite topic. But here’s the rundown. The Domestic Parking Garage is right near Terminals 1, 2, and 3 and works well for short stays. International Parking Garages A and G sit near the International Terminal and handle both short and long-term parking. If you’re gone for a while, the remote long-term lot is cheaper and they run shuttles to all the terminals.

There’s also ParkFAST if you want a reserved spot close to the terminal. It costs more, obviously. I used it once when I was running super late and honestly it was worth it that day. Wouldn’t do it every time though.

Security and Checking In

Security at SFO moves pretty well compared to some airports I’ve been through. The general advice is two hours before domestic, three hours before international. That tracks with my experience, though I’ve gotten through in under 30 minutes on a quiet Tuesday morning. TSA PreCheck and CLEAR are both available if you want to speed things up. I got PreCheck a few years ago and it’s been one of my better travel investments.

Check-in counters and self-service kiosks are in every terminal. Most airlines have decent apps now too, so I usually check in on my phone and go straight to security.

Food, Shopping, and the Good Stuff

SFO actually has pretty solid food options for an airport. You’ll find everything from quick coffee spots to sit-down restaurants. The International Terminal has duty-free shopping, which — I’ll be honest — I’ve been suckered into more than once. There’s something about being in an airport that makes buying overpriced cologne feel like a good idea.

The airline lounges are nice if you have access. The Centurion Lounge gets talked about a lot and it’s solid, though it can get crowded during peak times. What I think is kind of cool is the rotating art exhibits throughout the airport. You’re walking to your gate and suddenly there’s this gallery-quality installation on the wall. That’s what makes SFO endearing — it tries to be more than just a place you pass through.

Free Wi-Fi throughout the airport. Charging stations everywhere, which matters more than it should in 2024. There are kids’ play areas if you’re traveling with little ones, and pet relief stations in every terminal. They even have yoga rooms, which I’ve never used but always think about using. There’s also a medical clinic in the International Terminal.

Accessibility at SFO

SFO does a good job with accessibility. Wheelchair-accessible shuttles are available for getting around the airport and to parking. They have visual paging and TTY phones for travelers with hearing or vision needs. All airlines provide complimentary wheelchair service — just request it when you book or when you arrive. And the pet relief areas work for service animals and guide dogs too.

The Green Side of SFO

This is something I didn’t know until recently, but SFO has been pretty aggressive about sustainability. They’ve got recycling and composting programs aimed at reducing waste. They’re working toward carbon neutrality with energy-saving measures and smarter building designs. Water conservation is a big deal too — low-flow fixtures, drought-tolerant landscaping, that sort of thing. They’ve even got electric vehicle charging stations and bike parking for people who ride to the airport. Which, in the Bay Area, is actually a real thing people do.

A Little History

SFO started back in 1927 as Mills Field Municipal Airport. Kind of wild to think about what that must have looked like. By 1954 they renamed it San Francisco International Airport as international flights became a bigger deal. The new International Terminal opened in 2000 and was one of the largest in North America at the time. And in 2019, Terminal 1 got the Harvey Milk name after some significant upgrades.

There was a BART extension proposed back in 1983 to connect the airport to the rail system. That eventually happened and changed everything about how people access the airport.

What’s Coming Next

They’re still working on finishing up the Harvey Milk Terminal 1 upgrades. More sustainability projects are in the pipeline — energy and water conservation stuff. They’re also looking at newer security and check-in technology to keep lines moving. And there’s ongoing work with local communities and businesses, which is nice to see an airport actually caring about.

My Tips for SFO

After years of flying through SFO, here’s what I’d tell a friend. Check your flight status before you leave home — delays happen and there’s no point sitting at a gate for three extra hours. Book parking or a ride ahead of time, especially around holidays. Arrive early enough that you’re not sprinting through the terminal. Use mobile check-in. And honestly, spend five minutes looking at a terminal map before you go. It saves so much confusion.

SFO isn’t perfect. No airport is. But it’s got solid bones, good transit connections, and enough food and amenities that even a long layover isn’t terrible. I’ve had worse afternoons than grabbing a decent meal and wandering through an art exhibit while waiting for a flight.
