        "question": "What is the typical flight duration from Tokyo to Seoul?",
        "answer": "A nonstop flight from Tokyo (NRT) to Seoul (ICN) typically takes about 2 hours 30–40 minutes. With a layover, total time often ranges from 5 to 8 hours, depending on the connection. The return flight from Seoul to Tokyo is slightly shorter, usually around 2 hours 10–20 minutes due to prevailing winds. Airlines like Korean Air and Asiana offer efficient nonstop services on this route."
      },
      "q1": {
        "question": "Are there any direct flights from Tokyo to Seoul?",
        "answer": "Yes, there are many direct flights from Tokyo Narita (NRT) to Seoul Incheon (ICN) — 12 airlines operate non‑stop service on this route, with flights running daily on most carriers. Korean Air (KE) leads with 49 weekly flights, followed by Jin Air (LJ) at 32, Asiana (OZ) and Jeju Air (7C) at 28 each, and several others including Eastar Jet (ZE), Air Seoul (RS), T'way Air (TW), Air Busan (BX), and Air Japan (ZG) all offering daily frequencies; Ethiopian Airlines (ET) and Air Premia (YP) fly 6 days a week (not Tuesdays). In total there are over 240 weekly non‑stop departures, with the first flights departing around 8:55 AM and the last around 8:55 PM.",
        "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.",

      "q2": {
        "question": "Are there visa requirements to travel from Tokyo to Seoul?",
        "answer": "Yes, visa requirements depend on your nationality. Japanese passport holders can enter South Korea visa-free for short stays (usually up to 90 days) under the visa waiver agreement, but South Korea now requires all visa-free foreign visitors to obtain a Korea Electronic Travel Authorization (K-ETA) before boarding. As of 2024, the K-ETA is mandatory for Japanese citizens. South Korean nationals do not need a visa to enter Japan for short stays (typically up to 90 days). If you hold a passport from a third country, check both Japan's and South Korea's entry rules based on your nationality. Also confirm whether you need a visa to transit or enter Japan if you are not a Japanese resident."

        "question": "What are the ground transportation options in Seoul?",
        "answer": "From Incheon International Airport (ICN) to Seoul city center, the AREX Express train is the most popular choice, reaching Seoul Station in about forty-three minutes nonstop. The AREX All-Stop train takes about an hour and is cheaper. Airport limousine buses serve many districts and hotels, offering comfort but variable travel times of sixty to ninety minutes depending on traffic. Taxis are available outside arrivals, with a trip to central Seoul taking roughly an hour and costing significantly more than transit. Ride-share services operate but may be less convenient than taxis. Car rentals are possible but not recommended due to Seoul's traffic and parking challenges. Most travelers prefer the AREX Express for its speed and reliability."

        "question": "Are overnight (red‑eye) flights available from Tokyo to Seoul?",
        "answer": "There are no nonstop red-eye flights from Tokyo Narita (NRT) to Seoul Incheon (ICN). Connecting options exist with an overnight leg — for example, an MIAT Mongolian Airlines itinerary with a red-eye segment from NRT to Ulaanbaatar (UBN) departing around 9:30 PM and arriving at 2:05 AM, followed by a long layover and onward flight to Seoul.",
        "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.",

      },
      "q13": {
        "question": "How do I get to Narita Intl Airport from the city center?",
        "answer": "From central Tokyo to Narita, the Narita Express train takes about 1 hour and is popular for its speed and comfort. The Keisei Skyliner is slightly faster to Nippori/Ueno. Airport limousine buses take 75–110 min depending on traffic and cost less. Taxis and rideshares are very expensive and not recommended. Driving and parking are costly and rarely used."
