The San Francisco International Airport's (SFO) terminal that is utilised by the American ultra-low-cost airline Frontier Airlines is most likely meant when the term "Frontier Terminal SFO" is used.
Operating out of Terminal 1 at SFO, sometimes referred to as the Harvey Milk Terminal, is Frontier Airlines. It's a great way to start your day. Before flying Frontier Airlines out of SFO, passengers should verify their gate and terminal information by consulting their flight itinerary.
