        "question": "What is the typical flight duration from Tokyo to Seoul?",
        "answer": "The flight from Tokyo Haneda to Seoul is about 750 miles and typically takes 2 hours 35 minutes nonstop. On the return leg, prevailing winds shorten the journey to about 2 hours 10 minutes.",
        "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": "What are the ground transportation options in Seoul?",
        "answer": "At Gimpo International Airport, the fastest and most-used way to reach central Seoul is the AREX commuter rail, which runs nonstop to Seoul Station in about 20-25 minutes. The airport is also directly served by Seoul Metro lines 5, 9, the Gimpo Goldline, and the Seohae Line, giving easy transfers across the city. Taxis are readily available, with regular and deluxe tiers, and ride-share apps like Kakao T are popular. Car rentals exist but are rarely used for city-center trips due to excellent public transit and traffic. Overall, the subway/AREX network is the highest-quality option for most travelers.",

        "methodology": "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.",

        "answer": "Nonstop flights from Tokyo Haneda (HND) to Seoul are operated by All Nippon Airways (NH), Korean Air (KE), Japan Airlines (JL), Asiana Airlines (OZ), and Peach Aviation (MM). Most services land at Gimpo (GMP), where ANA and Korean Air each offer 42 weekly flights, Japan Airlines 35, and Asiana 28. Asiana, Korean Air, and Peach also serve Incheon (ICN) with a combined 22 weekly departures, including overnight options. Specific median fares are not listed in the schedule data for this route.",

      },
      "q12": {
        "question": "Which airport should I use in Seoul?",
        "answer": "Incheon is the primary international airport, located 48 km west of central Seoul, serving most full‑service carriers and long‑haul flights. Gimpo is closer to the city centre and mainly handles domestic and regional services, including flights to Tokyo Haneda."
      },
      "q13": {
        "question": "How do I get to Haneda Intl Airport from the city center?",
        "answer": "From central Tokyo, the fastest and most popular ways to reach Haneda Airport are the Keikyu Line or Tokyo Monorail, which offer frequent, relatively inexpensive connections from major stations like Shinagawa and Hamamatsucho. Airport limousine buses serve Tokyo, Kanagawa, Chiba, Saitama, and other Kanto destinations, providing a convenient though slower and often pricier option. Taxis and ride-shares are available but are the most expensive for the roughly 20–30 minute ride, while driving and parking at Haneda is possible but discouraged during peak periods due to congestion, with public transport actively promoted.",
