It serves as a major hub for United Airlines and Alaska Airlines, with four runways—two of which extend into the bay—and an internationally accredited airport museum. SFO is known for its fog-related delays, AirTrain people mover, and direct BART rail service to downtown.

🚖 Getting There
BART is usually the fastest and cheapest way to reach downtown San Francisco, with trains from the International Terminal running frequently. The free AirTrain connects terminals, parking, and the rental car center, while taxis and ride-hailing have designated pickup areas at each terminal.
