For anyone flying out of San Francisco with Frontier Airlines, knowing your way around the frontier airlines sfo terminal can help you avoid last-minute stress and get your trip started on the right foot. Frontier is known for being a budget-friendly airline, but navigating the airport can sometimes feel like anything but simple—especially if you’re not familiar with SFO.
San Francisco International Airport is a sprawling hub, serving millions of travelers each year. It has multiple terminals, each with its own structure, airline partners, and amenities. If your ticket says "Frontier," that means you're heading into Terminal 1, officially known as the Harvey Milk Terminal.
In this guide, we'll cover everything from where to find Frontier check-in to the best spots for food, tips to get through security faster, and answers to common questions about the frontier airlines sfo terminal. Whether you're a seasoned traveler or flying out of SFO for the first time, there's something useful here for you.
Let’s start with the basics. Frontier Airlines operates all of its flights out of Terminal 1 at San Francisco International Airport. This terminal handles many domestic carriers and has undergone significant renovations in recent years to make it more traveler-friendly.
The remodeled terminal now offers a bright, open environment with upgraded seating, modern restrooms, and better passenger flow. You won’t find long, winding corridors or outdated signage here—Terminal 1 was designed to make things easier.
That said, this terminal still serves a high volume of passengers, so knowing what to expect when you arrive makes a difference.
Whether you’re arriving at the airport by rideshare, public transit, or driving yourself, getting to the frontier airlines sfo terminal is relatively straightforward.
Driving or Parking
If you're driving, set your GPS to Terminal 1 or Harvey Milk Terminal. The closest and most convenient parking garage is Garage B, which is connected to Terminal 1 via a short pedestrian bridge. This garage offers hourly and daily parking and tends to fill up quickly during peak travel periods.
Rideshare Services
Uber, Lyft, and other rideshare apps operate at SFO. Drivers will drop you off right outside Terminal 1's departure level. Be sure to select “Terminal 1” in your app to avoid confusion, as SFO is a large airport with multiple terminals.
Public Transportation
Taking BART is one of the easiest ways to reach SFO. Once you arrive at the SFO BART station, follow signs to the AirTrain Blue Line. The AirTrain is a free, automated tram that connects all terminals, garages, and rental car facilities. Get off at the Terminal 1 stop, and you're just steps from the Frontier check-in counters.
At the frontier airlines sfo terminal, check-in is located on the departure level. You’ll find a mix of traditional service counters and self-service kiosks. If you've checked in online and don’t have a checked bag, you can skip the counter altogether and head straight to security.
But if you’re checking bags, keep in mind that Frontier is very strict with luggage policies. Make sure your bag meets their size and weight requirements before you arrive. Otherwise, you'll be charged extra—sometimes significantly more—at the airport.
To speed things up, consider the following:
Use the Frontier app to check in before arriving
Print your boarding pass or use the mobile version
Prepay for bags online to save money
Weigh your bag before you leave home
After checking in, the next stop is TSA. The frontier airlines sfo terminal has a central security checkpoint shared by all airlines operating in Terminal 1. It’s modern, organized, and generally efficient, though wait times can vary based on the time of day.

If you're enrolled in TSA PreCheck, use the dedicated lane

Once you’re through security, you’ll enter the post-security area of Terminal 1, which includes Frontier's gates as well as restaurants, shops, and seating areas.
Frontier primarily uses gates in Boarding Area B. The walk from security to your gate is short, usually under five minutes. Even better, the area around the gates is spacious, clean, and well laid out.
