        "question": "What is the typical flight duration from Seoul to San Francisco?",
        "answer": "The flight from Seoul to San Francisco is about 5,640 miles and typically takes around 10 hours and 40 minutes nonstop. The return flight is longer, at about 12 hours and 40 minutes, due to prevailing headwinds.",
        "methodology": "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.",

        "answer": "Yes, four airlines fly nonstop from Seoul Incheon to San Francisco: United (UA), Korean Air (KE), Air Premia (YP), and Asiana (OZ). United operates five daily departures, Korean Air and Asiana each run one daily flight, and Air Premia flies once daily on Monday, Wednesday, Friday, Saturday, and Sunday. Together they offer about 66 weekly nonstops, with flight times around 10 to 11 hours eastbound.",

        "answer": "BART rapid rail is the fastest and most-used way to reach downtown San Francisco, with the station located in the International Terminal. Lyft, Uber, Wingz, and taxis are available for door-to-door service, picking up at the Domestic Garage or arrivals curb. Waymo autonomous rides are also an option for select passengers from the Rental Car Center. Rental cars are accessible via the AirTrain Blue Line, and many hotels offer complimentary shuttles.

Comfortable airport limousine buses connect major districts like Gangnam, Myeongdong, and Dongdaemun without the need to transfer, with fares around 17,000–18,000 KRW. Taxis and ride‑share services offer door‑to‑door convenience at a higher cost, and driving yourself is possible with both short‑term and long‑term parking at the airport.",

        "methodology": "Airlines and weekly frequencies are compiled from our flight-schedule database, which combines published airline timetables, U.S. government schedule data from the Bureau of Transportation Statistics (BTS), and observed flight operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI). 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.",
