Frontier Airlines operates out of Terminal 1, also known as the Harvey Milk Terminal, at San Francisco International Airport. Terminal 1 has recently undergone significant renovations, making it one of the most modern and traveler-friendly terminals at SFO. The layout is clean, intuitive, and equipped with all the necessary amenities for a smooth travel experience. It serves several domestic carriers, and Frontier Airlines passengers will find clear signage to direct them to check-in counters, security checkpoints, and departure gates.
