Everything You Need to Know About the Frontier Airlines San Francisco Terminal

San Francisco International Airport (SFO) is one of the busiest and most iconic airports in the United States, serving millions of travelers every year. With its stunning architecture, international reach, and eco-conscious design, SFO is a favorite among frequent flyers. But if you're flying with a budget airline like Frontier, it's important to know the ins and outs of the Frontier Airlines San Francisco terminal to make your travel day smoother.

Whether you're a first-time flyer with Frontier or a seasoned traveler trying to avoid unnecessary stress, this article will walk you through exactly what to expect when flying with Frontier Airlines out of San Francisco.

Which Terminal Does Frontier Airlines Use at SFO?

Frontier Airlines operates out of Terminal 1 at San Francisco International Airport. More specifically, flights typically depart from Boarding Area B. Terminal 1 is also known as the Harvey Milk Terminal, named in honor of the pioneering LGBTQ+ civil rights leader and former San Francisco supervisor.

The terminal itself underwent a massive renovation in recent years and now boasts a modern, spacious design with plenty of amenities for travelers. Even though Frontier is a low-cost carrier, the terminal experience at SFO doesn’t feel “budget” at all.

When you’re looking for the Frontier Airlines San Francisco terminal, just follow the signs for Terminal 1 once you arrive at the airport. It’s well-marked and easy to access from both public transit and rideshares.

Getting to Terminal 1

SFO is well-connected by several transportation options, and getting to Terminal 1 is relatively easy no matter how you're traveling.

• Driving or Rideshare: If you're being dropped off, just follow the signs to Terminal 1 on Highway 101. Curbside drop-off is quick and convenient.
  
  
• BART (Bay Area Rapid Transit): One of the most eco-friendly and efficient ways to reach SFO is via BART. Take the Pittsburg/Bay Point–SFO/Millbrae line and get off directly at the airport station. From there, just follow the signs to Terminal 1.
  
  
• AirTrain: If you're parking in the long-term lot or arriving at a different terminal, hop on the free AirTrain, which loops around the airport and makes stops at all terminals.
  
  

Once you're in Terminal 1, look for Frontier’s check-in counters and proceed to the security checkpoint for Boarding Area B.

Check-In and Baggage Info

Frontier Airlines encourages all travelers to check in online before arriving at the airport. You can check in via the Frontier app or website starting 24 hours before your flight. Doing so can save you time and avoid waiting in line at the terminal.

If you do need to check bags, head to the Frontier Airlines counter in Terminal 1. Keep in mind that Frontier is a low-cost carrier, which means they charge extra for everything from carry-on luggage to seat selection. Make sure you’ve paid for any bags or upgrades in advance—doing so at the airport usually costs more.

Pro tip: Weigh your bags before you leave home! Frontier has strict size and weight limits for both carry-on and checked luggage.

Security and Boarding

Security lines at Terminal 1 can vary depending on the time of day, but in general, they move at a decent pace thanks to the renovated infrastructure. If you have TSA PreCheck, there’s a dedicated lane that usually speeds things up significantly.

Boarding for Frontier flights is done in zones, and you’ll find your boarding group listed on your mobile or printed boarding pass. Remember, Frontier charges for carry-on bags, so if you haven’t purchased one, you’re limited to just a personal item (like a backpack or purse) that fits under the seat in front of you.

Amenities in the Frontier Airlines San Francisco Terminal

One of the pleasant surprises when flying Frontier out of SFO is the quality of the terminal itself. Terminal 1 is bright, clean, and filled with local touches that reflect San Francisco’s culture and cuisine.

Here are some highlights:

• Dining: There’s no shortage of food options near Boarding Area B. Whether you're craving artisanal coffee, a sushi roll, or a classic burger, you’ll find something to satisfy your hunger.

• Art Installations: SFO is known for incorporating local art into its terminals, and Terminal 1 is no exception. Take a moment to enjoy the exhibits while you wait.
  
  

Even though Frontier itself keeps things pretty no-frills on board, the Frontier Airlines San Francisco terminal experience feels elevated and comfortable.

Frontier’s Approach to Budget Travel

Flying with Frontier Airlines is all about understanding what’s included—and what’s not. Their ultra-low-cost model means your base fare gets you a seat on the plane and not much more. If you want a carry-on, seat selection, or snacks onboard, those all come with an additional charge.

That said, for travelers who pack light and plan ahead, Frontier can be an excellent way to travel affordably. And with the upgrades at SFO’s Terminal 1, your airport experience doesn’t have to feel budget at all.

1. Check In Online: Always check in ahead of time to skip the lines.
   
   
2. Weigh Your Bags: Be sure your luggage meets Frontier’s strict guidelines.
   
   
3. Arrive Early: Aim to arrive at least 2 hours before your flight—especially if you're checking bags.
   
   
4. Bring Snacks: Frontier doesn’t offer complimentary food or drinks, so pack your own.
   
   
5. Use the Terminal Amenities: Make the most of Terminal 1’s great food, charging stations, and relaxed vibe.
