        "question": "What is the typical flight duration from Seoul to Tokyo?",
        "answer": "The flight from Seoul Gimpo to Tokyo is about 730 miles and typically takes 2 hours 10 minutes nonstop, with the return leg to Seoul taking 2 hours 30 minutes due to prevailing winds.",
        "methodology": "Flight times and distances come 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). 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. Distance is the great-circle distance between the two airports, so the actual flown track is typically 2-5% longer.",

        "question": "Are there any direct flights from Seoul to Tokyo?",
        "answer": "Yes, there are plenty of non‑stop flights from Seoul (GMP) to Tokyo (TYO), all landing at Haneda (HND). Four airlines — ANA (NH), Asiana (OZ), Korean Air (KE), and JAL (JL) — operate daily service, together offering about 140 departures a week from early morning through late evening. The flight takes roughly 2 hours 10 minutes eastbound and about 2½ hours on the return.",
        "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. Red-eye flights are identified from scheduled local departure and arrival times in our flight-schedule database — built from published airline timetables and official schedule data, including U.S. Department of Transportation records for domestic routes — flagging services that depart late at night and arrive the following morning; for connecting itineraries the red-eye is based on the timing of the overnight long-haul leg. 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. Aircraft types are taken from the equipment each operating carrier schedules on this route, drawn from published airline timetables and airline equipment schedules in our flight-schedule database. They describe typical scheduled aircraft and can vary with seasonal or day-of-week assignments and last-minute equipment swaps.",

        "answer": "Tokyo Haneda Airport (HND) offers excellent ground transportation to central Tokyo, primarily via the Keikyu Line and the Tokyo Monorail, with the monorail operating since 1964 and connecting to Hamamatsucho Station. Airport access buses serve Tokyo, Kanagawa, Chiba, Saitama, and other Kanto regions, providing another reliable option. Taxis and car rentals are available, though driving and parking are discouraged due to congestion, and a new JR East Haneda Airport Access Line is under construction with direct service to Tokyo Station expected by fiscal year 2031. The Tokyo Monorail and Keikyu Line are the most used and fastest options, with travel times around 20–30 minutes to central Tokyo.",

        "question": "Which airport should I use in Tokyo?",
        "answer": "Narita is the main international gateway, handling most long‑haul and full‑service flights from GMP, but it is farther from central Tokyo. Haneda is closer to downtown and popular for domestic and regional routes, including some international services, making it a convenient choice for business travellers."

        "question": "How do I get to Gimpo Intl Airport from the city center?",
        "answer": "From Seoul city center, the fastest and most popular way to reach Gimpo International Airport is by subway: the airport has its own station served by Seoul Subway Lines 5 and 9, the AREX airport railroad, the Gimpo Goldline, and the Seohae Line, so you can ride directly from downtown without traffic. Public buses also connect the airport to the city, and taxis (regular or deluxe) offer a door-to-door option that is pricier but convenient with luggage. Ride-share services are available in Seoul, though they function more like premium taxis, and driving yourself is possible with airport parking, but it's generally the least convenient for a short trip from the center. Overall, the subway is the cheapest and most reliable choice for most travelers.",
