But with budget travel comes the need for a little more planning—especially at the airport.

In this guide, we’ll walk you through what to expect at the Frontier Airlines SFO terminal, from check-in and security to terminal amenities and boarding tips. Whether you’re a seasoned traveler or heading out on your first Frontier flight, this guide will help you travel smarter.

Which Terminal Does Frontier Airlines Use at SFO?

Frontier Airlines operates from Terminal 1 at SFO, commonly referred to as the Harvey Milk Terminal. This terminal is modern, efficient, and designed to handle a high volume of domestic flights. Though it serves several airlines, navigating the Frontier Airlines SFO terminal is relatively straightforward thanks to clear signage, updated facilities, and helpful airport staff.

Checking In with Frontier at SFO

One of the most important things to know when flying Frontier is that it’s a self-service focused airline. To save both time and money, it’s highly recommended to check in online or through the Frontier mobile app up to 24 hours before your flight. This will allow you to:

• Avoid long lines at the airport

• Secure your boarding pass digitally

• Pre-pay for bags at a lower cost

For those who need assistance or prefer to check in at the airport, there are self-service kiosks available in the Frontier Airlines SFO terminal, along with staffed counters if needed. Keep in mind that printing a boarding pass at the counter may come with a small fee, so going digital is often the smarter choice.

Baggage and Fees

Frontier’s low fares are appealing, but they don’t include much beyond the seat. The only included item is one personal bag that fits under the seat in front of you. If you plan to bring a carry-on or check a bag, you’ll need to pay for it separately.

To avoid paying more at the airport, purchase your baggage allowance online before arriving at the Frontier Airlines SFO terminal. Baggage fees increase the closer you get to departure, and paying at the gate is typically the most expensive option.

Also, bag size matters. Frontier is strict about enforcing baggage size and weight limits, and gate agents will check your bag dimensions. Be sure your personal item fits within their specified size to avoid unexpected charges.

Security at the SFO Frontier Terminal

After checking in and tagging any bags, your next stop is the security checkpoint. Terminal 1 is equipped with modern TSA screening technology, and while lines are generally efficient, wait times can vary depending on the time of day and travel season.

TSA PreCheck is available at the Frontier Airlines SFO terminal, so if you’re enrolled in the program, you can use the expedited security line. This can be a big time-saver, especially during peak hours.

It’s a good idea to arrive at the terminal at least two hours before your flight. This gives you enough time to check in, go through security, and get to your gate without rushing.

Amenities at Terminal 1 for Frontier Travelers

One of the benefits of flying from the Frontier Airlines SFO terminal is access to Terminal 1’s impressive amenities. Recent renovations have made this terminal one of the most traveler-friendly areas of the airport. Here’s what you can expect:

• Dining Options: Terminal 1 offers a variety of food choices, from sit-down restaurants to quick-service cafes. Whether you want a fresh salad, a hot sandwich, or a cup of gourmet coffee, there’s something for every appetite.

• Shopping: Need a travel pillow, a last-minute gift, or some reading material? The terminal includes several retail shops that carry travel essentials and more.

• Free Wi-Fi: Stay connected with fast, complimentary Wi-Fi available throughout the terminal.

• Charging Stations: Don’t worry about running out of battery. Most gate areas are equipped with plenty of power outlets and USB ports.

• Family-Friendly Spaces: The terminal includes nursing rooms and changing stations, making it easier for families with small children to travel comfortably.

Boarding the Plane

Frontier uses a zone boarding process, typically based on the type of ticket and baggage you’ve purchased. If you’ve bought priority boarding or are carrying a paid carry-on, you’ll board earlier. If you’re traveling with only a personal item, you’ll likely board in one of the later groups.

Make sure to listen carefully for announcements at the gate and have your boarding pass ready—either printed or on your phone.
