There’s a lot to know about getting through this terminal quickly and comfortably.
From baggage rules and check-in procedures to food options, gate areas, and transportation, this detailed breakdown covers every part of the Frontier experience at SFO. If you’ve got a flight coming up—or you just like to be extra prepared—this guide will help you navigate Terminal 1 like a pro.
Where Is Frontier Airlines Located at SFO
Frontier Airlines operates solely from Terminal 1 at San Francisco International Airport. This terminal is one of the newest and most modern at SFO. It has gone through multiple phases of renovations and expansions, with the goal of improving the passenger experience and streamlining operations.
Terminal 1 serves several domestic carriers, but Frontier typically uses gates in Boarding Area B. The walk from check-in to the gates is relatively short compared to other terminals. Wide walkways, plenty of signage, and easy access to key amenities make the experience smoother than most travelers expect.
What to Expect at Check-In
The frontier airlines sfo terminal offers both staffed counters and self-service kiosks on the departure level of Terminal 1. If you haven’t checked in online, these machines will let you print your boarding pass and bag tag. If you’re traveling with carry-on only, you might not even need to speak to an agent.
However, if you’re checking bags—or if you have questions about fees or seating—you’ll need to stop at the main counters. Keep in mind that Frontier is a budget airline, and nearly every add-on comes with a charge. That includes checked baggage, carry-on luggage, seat selection, and even printed boarding passes at the airport.
Pro tip: Pay for all your extras online before arriving at the terminal. Not only does it save money, but it also cuts your time at the counter.
Security Screening and TSA PreCheck
After checking in, head to the TSA security screening area. Like the rest of Terminal 1, this zone is updated, efficient, and usually well-staffed. Still, security wait times can vary depending on the time of day and the season.
The frontier airlines sfo terminal includes a dedicated TSA PreCheck lane, which is especially useful during the early morning or evening rush. If you’re not enrolled in PreCheck, be prepared to wait a little longer during busy travel hours.
Once you clear TSA, you’re just steps away from the Frontier gates—and you’ll find plenty of reasons to explore the terminal before boarding.
Layout and Design of Terminal 1
Terminal 1’s updated design focuses on passenger comfort. The concourse is flooded with natural light and offers a spacious feel. The seating areas near the gates include USB ports and charging stations, and the restrooms are well-maintained and accessible.
Art installations throughout the terminal reflect Bay Area culture, and the interior layout makes it easy to find your way. There are also plenty of monitors with real-time flight info, helping travelers stay up to date on gate changes or boarding calls.
Where to Eat and Drink in Terminal 1
The food options near the frontier airlines sfo terminal are much better than what you might expect from a low-cost carrier zone. You’ll find a good mix of casual dining, coffee shops, and grab-and-go options. Some popular choices include:
Amy’s Drive Thru – Organic and vegetarian fast food that’s popular with locals
Dogpatch Bakehouse & Caffè – Ideal for a quick bite or coffee on the go
Napa Farms Market – Farm-to-table sandwiches, snacks, and local products
Green Beans Coffee – Specialty coffee drinks and pastries
Prices are airport-standard, but quality is decent, and lines move quickly even during busy periods.
Wi-Fi, Charging, and Tech Amenities

Accessibility and Passenger Support
Terminal 1 is built with full ADA compliance in mind. Wheelchair service is available through Frontier and can be arranged at the time of booking or requested at the airport. Elevators, wide walkways, and accessible restrooms make travel smoother for passengers with mobility needs.
There are also family restrooms, nursing stations, and a children’s play area located near the gates. Traveling with kids? The play zone is a great way to let little ones burn off energy before a long flight.
Getting to Terminal 1 at SFO
If you’re driving yourself, Garage B is the closest parking structure to Terminal 1. It connects to the terminal by a short walkway, and you can pay using credit card, mobile wallet, or reservation systems online. Short-term and long-term rates are available.
Rideshare drop-offs (Uber, Lyft, etc.) happen directly outside the departure level of Terminal 1. If you’re using a car service or taxi, look for signs pointing to the designated curbside zones.
Prefer public transit? Take BART to the airport station, then hop on the AirTrain Blue Line to reach Terminal 1. The AirTrain is free, operates 24/7, and connects all terminals, garages, and the rental car center.
What Frontier Passengers Should Know About Boarding
Boarding for Frontier flights is usually fast-paced, and the airline follows a numbered zone system. Your boarding group will depend on your seat selection and whether you purchased carry-on or priority services.
Keep your ID and boarding pass ready as gate agents scan quickly. Be sure to listen for announcements in case of gate changes or updated departure times.
Once you board, you’ll notice Frontier’s basic cabin style. Seats are slimline, there’s no in-seat entertainment, and legroom is tighter than legacy carriers. Bring your own snacks, water, and entertainment to stay comfortable during your flight.
