Traveling with Frontier Airlines from San Francisco International Airport (SFO)? Understanding your departure terminal, check-in process, and available airport services can help ensure a hassle-free journey. As a popular low-cost airline, Frontier Airlines offers budget-friendly fares, but travelers should be aware of the airline’s specific policies, including baggage fees, online check-in procedures, and optional add-ons to avoid unexpected costs.
Frontier Airlines operates out of Terminal 1 (Harvey Milk Terminal) at SFO, a modern facility designed for domestic flights with efficient security checkpoints, self-service kiosks, dining options, and comfortable waiting areas. Passengers are advised to complete online check-in in advance and arrive at least two hours before departure to allow enough time for security screening and boarding. If you need more information about check-in counters, baggage rules, or terminal facilities.
