        "question": "What is the typical flight duration from Tokyo to Seoul?",
        "answer": "The flight from Tokyo to Seoul covers about 750 miles and typically takes 2 hours 40 minutes. The return leg is about 20 minutes shorter at 2 hours 20 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": "What are the ground transportation options in Seoul?",
        "answer": "From Incheon Airport (ICN) to central Seoul, the fastest option is the AREX Express train, which reaches Seoul Station in about 43 minutes. The all-stop commuter train is a cheaper rail alternative, while airport limousine buses serve major districts like Gangnam and Dongdaemun with fares around 17,000–18,000 KRW. Taxis and ride-hailing apps are readily available, and car rentals are possible but less common for city transfers. The AREX train is the most-used option for its speed and reliability.",

The specific aircraft types and median fares for these carriers aren't listed in the available data.",

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.

Osaka offers efficient domestic transfers within Japan, Busan provides a quick hop with streamlined transit, and Shanghai or Beijing feature broad international connections and visa-free transit options for eligible passengers."

        "question": "Which airport should I use in Seoul?",

      },
      "q13": {
        "question": "How do I get to Haneda Intl Airport from the city center?",
        "answer": "From downtown Tokyo, the fastest and most popular way to reach Haneda Airport is by train — either the Tokyo Monorail from Hamamatsucho Station (about 15–20 minutes) or the Keikyu Line from Shinagawa Station (around 10–15 minutes). Limousine buses serve major hotels and stations with door-to-terminal convenience, though travel time varies with traffic. Taxis and ride‑share are available but cost significantly more, while driving yourself means using the Shuto Expressway and paying for airport parking.",

The exact aircraft varies by airline and day, and many flights list an unspecified type, so the metal can change; Wi‑Fi and seatback entertainment are widely available across the carriers on this route.",

The Delta Sky Club and The Centurion Lounge offer premium amenities like showers and hot meals, accessible with eligible premium tickets, elite status, or certain credit cards. Sky Lounge South and TIAT Lounge are contract lounges generally available to business-class travelers, elite members, and Priority Pass holders, with the TIAT Lounge offering 24-hour access.
