Flair Airlines SFO Terminal Serving both domestic and international flights, Flair Airlines SFO Terminal is based out of San Francisco International Airport's (SFO) Terminal 1. Keep in mind that Flair is a low-cost airline, which means that extra fees are charged for things like meals, seat preference, and checked bags. Examine the baggage policy and check in online before you go to the airport to avoid any surprises. Be prepared for potential wait lines at security or check-in by arriving early. Although Terminal 1 has a number of food and shopping options, the limited amenities onboard make it faster to bring snacks and entertainment for the journey.
