Terminal 1 at SFO: The Frontier Airlines Hub
Frontier Airlines operates exclusively out of Terminal 1 at San Francisco International Airport.

If you’re arriving by car or rideshare, the drop-off point for Frontier is located just outside Terminal 1 Departures. You’ll be greeted by automatic glass doors that lead you directly into the check-in area. Curbside staff are typically available to direct you or assist passengers needing wheelchair access.
Parking is just as convenient. The best option is Garage B, which is connected to Terminal 1 via a pedestrian bridge. It’s great for both short-term drop-offs and long-term parking.
