Overview of SFO Airport Lounges

San Francisco International Airport is home to a variety of lounges spread across its four terminals.

Whether you’re a frequent flyer with elite status, a credit card holder with lounge perks, or simply willing to pay for a day pass, you’ll likely find a lounge that suits your needs.

Each lounge offers different amenities, including free Wi-Fi, showers, dining options, and even premium alcohol selections.

However, not all lounges are created equal—some cater to specific airlines like United, while others are affiliated with programs like Priority Pass.

Let’s break down the main lounges at SFO and what they offer.

United Club Lounges at SFO

If you’re flying with United Airlines, you’re in luck. United operates three United Club lounges at SFO, located in Terminals 3 and the International Terminal.

These lounges are the perfect stop if you’re flying domestically or internationally with United.

They offer a quiet space with complimentary snacks, beverages (yes, alcoholic ones too), high-speed Wi-Fi, and workstations for business travelers.

The most popular location is the SFO Airport United Lounge in Terminal 3 near gate F11, primarily serving United’s domestic routes.

If you’re flying internationally, United’s Polaris Lounge in the International Terminal takes the experience up a notch, offering full meals and luxury amenities like showers.

Flying economy but want to access the United airport lounge at SFO? You can purchase a day pass for $59, though it’s subject to space availability.

It might be worth it if you’re facing a long layover or just need some peace and quiet.

American Express Centurion Lounge at SFO

When it comes to luxury, few lounges beat the American Express Centurion Lounge at SFO, located in Terminal 3. This lounge is available to  The Platinum Card® from American Express and Centurion cardholders, and it’s a traveler favorite for its upscale ambiance, gourmet meals, premium cocktails, and even locally inspired dishes.

The Centurion Lounge at San Francisco Airport is ideal if you want to indulge a little before your flight. With custom craft cocktails, a selection of wines, and a calm atmosphere, it’s the perfect retreat for Amex members. You’ll also find excellent shower facilities to freshen up before a long flight.

Pro tip: The Centurion Lounge at SFO is popular, and during peak travel times, it can get crowded. Luckily, they now allow you to reserve a spot on the app up to 30 minutes before arrival.

SFO Airport Priority Pass Lounges

Priority Pass members have a couple of solid options at SFO.

The most well-known is The Club at SFO, located in the International Terminal, which offers everything you’d expect: snacks, drinks, showers, and a quiet place to relax. Priority Pass members can enjoy this lounge free of charge, and it’s also accessible via day passes.

In addition to lounges, Priority Pass members can also use their membership at restaurants like Yankee Pier in Terminal 3, where you can enjoy a sit-down meal before your flight.

It’s worth noting that not all Priority Pass lounges and restaurants are accessible 24/7, so be sure to check the hours if you have an early or late flight.

The SFO Airport Priority Pass Lounge options offer variety and flexibility, making them a good choice for frequent travelers who don’t always fly with one particular airline.

SFO’s Best Airport Lounge – Which One to Choose?

So which is the best airport lounge at SFO? It depends on what you’re looking for. If luxury is your top priority, Amex’s Centurion Lounge at San Francisco Airport will be your go-to.

For travelers looking for a quieter, business-friendly setting, the United Club Lounge offers comfort with a more corporate vibe. And if you’re a Priority Pass member, you’ll find the flexibility of multiple lounge and restaurant options attractive.

Here’s a quick breakdown of the highlights:

Can You Smoke in SFO Airport Lounges?

If you’re looking for a smoking lounge at SFO, I’ve got some bad news. There are no dedicated SFO Airport smoking lounges inside the terminals. 

The airport is completely smoke-free indoors, which means you’ll need to step outside before clearing security if you want to smoke.

Once you’re past security, it’s a no-smoking zone throughout the airport, lounges included. For smokers, this can be a little inconvenient, but it’s best to plan accordingly.

How to Access Lounges at SFO Without Elite Status

Not a member of any airline elite program? No problem. There are several ways you can still get lounge access at SFO, even if you’re flying economy.

Lounges in Different SFO Terminals

Here’s a quick look at where you can find lounges in each terminal:

• Terminal 1: Mostly domestic flights, with fewer lounge options. No major lounges here, but nearby in Terminal 2.
• Terminal 2: Alaska Airlines flyers can enjoy the Alaska Lounge.
• Terminal 3: Plenty of options here for United passengers, including multiple United Club Lounges and the Amex Centurion Lounge.
• International Terminal: Home to The Club at SFO, the United Polaris Lounge, and other international airline lounges like Cathay Pacific.

Amenities Offered at SFO Lounges

What can you expect in terms of amenities? Most SFO lounges offer:

Priority Pass Restaurants at SFO

If the lounges are too crowded, or you’d prefer a proper meal, Priority Pass gives you access to certain airport restaurants as well.

At SFO, Yankee Pier in Terminal 3 and San Francisco Giants Clubhouse in Terminal 1 are two dining options that allow Priority Pass members to enjoy complimentary meals (up to a set amount).

Lounges for Long Layovers at SFO

If you’re facing a long layover at SFO, spending some time in a lounge can make all the difference. The Club at SFO offers a quiet, comfortable space for travelers in the International Terminal.

If you have a Priority Pass, this is a great option, but you can also purchase a day pass if needed. Showers and workstations will help you make the most of your downtime, so you’re refreshed when it’s time to board.

Booking Lounge Access in Advance

Given the popularity of many lounges, particularly the Centurion Lounge at SFO, it’s a smart idea to book your access in advance, especially during peak travel times.

Some lounges, such as the Amex Centurion, allow you to reserve your spot 30 minutes before you arrive via their mobile app. This can help you avoid disappointment, as many lounges tend to reach capacity quickly.
