        "question": "What is the typical flight duration from Seoul to Tokyo?",
        "answer": "The flight from Seoul to Tokyo covers about 780 miles and typically takes 2 hours and 30 minutes nonstop. The return leg from Tokyo to Seoul is slightly longer at about 2 hours and 40 minutes due to prevailing winds.",
        "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.",

        "question": "Are there any direct flights from Seoul to Tokyo?",
        "answer": "Yes, there are many daily non‑stop flights from Seoul Incheon to Tokyo Narita. Twelve airlines operate the route, with a combined 261 weekly flights running every day of the week — Korean Air alone offers 56 weekly departures, Asiana 35, Jin Air 32, Jeju Air 28, T'way Air 21, Eastar Jet 21, Air Seoul 21, Air Busan 14, Ethiopian 13 (all days except Tuesday), Zipair 7, Thai VietJet 7, and Air Premia 6 (all days except Tuesday and Sunday).",

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.

        "question": "What are the ground transportation options in Tokyo?",
        "answer": "From Narita Airport, the fastest and most-used option is the Narita Express (N'EX) train, reaching Tokyo Station in about an hour with half-hourly service at peak times. The Keisei Skyliner is a competing express train offering similar speed to Ueno Station. Airport limousine buses provide direct hotel access, while taxis are available but expensive and slow due to distance. Rental cars are an option but rarely used for city-center transfers given Tokyo's efficient rail network and traffic.",

        "question": "How do I get to Incheon Intl Airport from the city center?",
        "answer": "From downtown Seoul, the AREX express train is the fastest and most popular way to reach Incheon International Airport, taking about 43 minutes non‑stop from Seoul Station. Airport limousine buses serve many city locations and offer a comfortable door‑to‑door alternative, though they are slower and slightly more expensive. Taxis and ride‑share services provide direct, private transport at a significantly higher cost, while driving yourself is possible with on‑site parking but rarely the most convenient choice for international travelers.",
