The typical flight time is the median scheduled block time across all carriers on the route, computed the same way in both directions so the difference reflects prevailing winds rather than any change in method.

We count each operating carrier's scheduled weekly departures and the days it flies; where there is no nonstop service, connecting carriers are identified by linking scheduled nonstop segments through common hub airports. Where a median fare is shown for a carrier, it reflects the real fares Priceline users found on this route in the last 72 hours. Carrier service, flight times and distances for this route come from our flight-schedule database, which draws on published airline timetables, U.S. government schedule data, and observed operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI). We report the days of the week and the departure times each carrier operates. The typical flight time is the median scheduled block time, given both per carrier and across all carriers on the route; where a schedule does not publish an elapsed time, it is derived from the scheduled departure and arrival times converted to UTC. Outbound and return times are computed by the same method, so the difference between them is directly comparable and reflects prevailing winds rather than any change in derivation. Distance is the great-circle distance between the two specific airports named, so an actual flown track is typically 2-5% longer. Where shown, on-time departure and arrival rates and cancellation rates come from the U.S. Bureau of Transportation Statistics (BTS) Airline On-Time Performance dataset, which covers U.S. domestic routes only; where a typical fare is shown, it comes from the U.S. DOT Airline Origin and Destination Survey (DB1B), a quarterly 10% sample of tickets sold.", "toolsUsed": [ "route_airlines", "flight_schedule" ] }, "q3": { "question": "What are the ground transportation options in San Francisco?", "answer": "San Francisco International Airport offers BART rapid rail directly from the International Terminal to downtown San Francisco and the East Bay, which is the fastest and most-used option into the city center.

Rental cars are centralized at the Rental Car Center accessible via the AirTrain Blue Line, and hotel shuttles plus shared airporters serve the region.

Booking roughly 30 days out yields the absolute lowest fares at about $476, while waiting until the last week or booking more than 5 months ahead can push prices above $550 to $719. For summer or holiday periods, you'd want to book earlier within that 4-6 week window or slightly beyond, since peak demand typically raises fares and reduces availability.", "methodology": "Booking-window guidance comes from the same monthly in-house analysis of Priceline's own air booking-summary archive.

Airport limousine buses also serve major hotels and stations across the city, and ride-share/taxis are available, though taxis can be expensive for the 15–20 km trip.
