        "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 minutes to 2 hours 45 minutes. With a layover, most commonly in Osaka or Busan, total travel time can extend to 4–6 hours. The return flight from Seoul to Tokyo is usually slightly shorter due to prevailing winds, often around 2 hours 20 minutes."
      },
      "q1": {
        "question": "Are there any direct flights from Tokyo to Seoul?",
        "answer": "Yes, there are many nonstop flights from Tokyo Narita (NRT) to Seoul Incheon (ICN). Twelve airlines operate the route with a combined total of over 240 weekly flights, all running daily except Ethiopian Airlines (ET) and Air Premia (YP) which operate six days a week (not Tuesdays).",
        "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 Tokyo to Seoul?",
        "answer": "Yes, visa requirements apply when traveling from Tokyo to Seoul, depending on your nationality. Japanese nationals can enter South Korea visa-free for short stays (typically up to 90 days for tourism) under a reciprocal agreement. South Korean nationals do not need a visa to enter Japan for short visits. Travelers of other nationalities should check both Japanese exit requirements and South Korean entry rules, as many nationalities require a K-ETA (Korea Electronic Travel Authorization) or a visa before travel."

      "q3": {
        "question": "What are the ground transportation options in Seoul?",
        "answer": "Seoul has two main airports: Incheon International (ICN) and Gimpo International (GMP). From Incheon, the AREX Express train reaches Seoul Station in about forty-three minutes non-stop, while the all-stop AREX commuter train takes around sixty minutes. Both are reliable and popular. Airport limousine buses serve many districts and are comfortable but slower in traffic. Taxis are widely available, with regular and deluxe options taking about an hour to central Seoul, though more expensive. Ride-share apps like Kakao T operate legally. Car rentals are available but not recommended for city travel due to congestion and parking challenges. From Gimpo, the AREX and subway lines connect to central Seoul in twenty to thirty minutes, and buses and taxis are also options. Most travelers use the AREX train for its speed, affordability, and direct connection to major stations."

        "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.",
