        "question": "What is the typical flight duration from Seoul to Tokyo?",
        "answer": "A nonstop flight from Seoul (ICN) to Tokyo (NRT/HND) typically takes about 2 hours 10 minutes to 2 hours 30 minutes. The return from Tokyo to Seoul is similar, often around 2 hours 20 minutes to 2 hours 40 minutes, though westbound flights can be slightly longer due to prevailing winds. With a layover, total travel time usually extends to 5–8 hours, depending on the connection point. Korean Air and Asiana often offer some of the fastest nonstop services on this route."
      },
      "q1": {
        "question": "Are there any direct flights from Seoul to Tokyo?",
        "answer": "Yes, there are many daily nonstop flights from Seoul Incheon (ICN) to Tokyo (TYO), with service to both Narita (NRT) and Haneda (HND). Korean Air (KE) and Asiana Airlines (OZ) operate the most frequencies, but Jin Air (LJ), Jeju Air (7C), T'way Air (TW), Eastar Jet (ZE), Air Seoul (RS), Air Busan (BX), Ethiopian Airlines (ET), ZIPAIR (ZG), Thai Vietjet Air (WE), Peach (MM), and Air Premia (YP) also fly the route nonstop, nearly all daily with some exceptions like Ethiopian and Air Premia running six days a week.",
        "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.",

        "question": "Are there visa requirements to travel from Seoul to Tokyo?",
        "answer": "Visa requirements for travel from Seoul to Tokyo depend on your nationality. South Korean nationals can enter Japan visa‑free for short stays (generally up to 90 days) for tourism or business. Japanese nationals do not need a visa to enter South Korea for short visits (typically up to 90 days under the visa waiver agreement). Nationals of other countries should check Japan's visa policy: many nationalities enjoy visa‑free entry for short stays, while others must obtain a visa before travel. Always verify with official sources before departure."

      "q3": {
        "question": "What are the ground transportation options in Tokyo?",
        "answer": "Tokyo is served by two main airports, Narita (NRT) and Haneda (HND). From Narita, the fastest option is the Keisei Skyliner, reaching Nippori in about thirty-six minutes, then connecting to the city. The Narita Express (N'EX) takes around fifty-three minutes to Tokyo Station and is popular because it is covered by the Japan Rail Pass. Limousine buses serve major hotels but are subject to traffic. Taxis are available but expensive and time-consuming. From Haneda, the Tokyo Monorail reaches Hamamatsucho in about thirteen minutes, while the Keikyu Line connects to Shinagawa in about eleven minutes; both integrate with central rail networks. Buses and taxis are also available. Ride-share is limited in Japan, and car rentals are impractical for city travel. Most travelers use the Narita Express or Skyliner from Narita, and the monorail or Keikyu Line from Haneda, due to their speed, frequency, and ease of connection."

        "question": "Are overnight (red‑eye) flights available from Seoul to Tokyo?",
        "answer": "Yes, overnight red-eye flights are available from Seoul (ICN) to Tokyo (TYO). Asiana Airlines operates daily red-eyes from ICN to Haneda (HND) departing around 9:10–9:30 PM, and Peach Aviation also runs a daily red-eye on the same route departing around 10:35 PM, with both arriving the next morning.",
        "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.",

        "question": "How do I get to Incheon Intl Airport from the city center?",
        "answer": "From central Seoul to Incheon Airport, the AREX Express train takes about 43 min nonstop and is the fastest. All-stop commuter trains and airport limousine buses are cheaper but slower. Taxis and rideshares offer door-to-door convenience at a high cost, and driving with long-term parking is possible but expensive."
