        "question": "What is the typical flight duration from Seoul to Tokyo?",
        "answer": "A nonstop flight from Seoul (ICN) to Tokyo (HND) typically takes about 2 hours 10 minutes to 2 hours 30 minutes. The return leg from Tokyo to Seoul is slightly shorter, averaging around 2 hours due to tailwinds. There are no common layovers on this short route, and multiple airlines offer similar flight times."
      },
      "q1": {
        "question": "Are there any direct flights from Seoul to Tokyo?",
        "answer": "Yes, non‑stop flights from Seoul Incheon to Tokyo Haneda run daily on three carriers: Korean Air (KE), Asiana (OZ), and Peach Aviation (MM). Korean Air and Asiana each operate two daily departures in the late evening (around 8:30–9:30 PM), while Peach flies one daily departure at 10:35 PM. Combined, there are about 35 non‑stop flights per week on the route.",
        "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. Where a median fare is shown for a carrier, it reflects the real fares Priceline users found on this route in the last 72 hours. Carrier service and weekly frequencies are summarized from our flight-schedule database, which draws on published airline timetables, U.S. government schedule data, and observed operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI). Where available, on-time and cancellation rates come from the U.S. Bureau of Transportation Statistics (BTS) Airline On-Time Performance dataset, and typical fares from the U.S. DOT Airline Origin and Destination Survey (DB1B), a quarterly 10% sample of tickets sold.",

        "question": "Are there visa requirements to travel from Seoul to Tokyo?",
        "answer": "Yes — visa requirements depend on your citizenship. South Korean nationals can enter Japan visa-free for short stays (up to 90 days for tourism). Japanese nationals can enter South Korea visa-free for short stays (up to 90 days). Travelers of other nationalities should check Japan's visa policy and South Korea's visa policy based on their passport. Always verify the latest rules before traveling, as policies can change."
      },
      "q6": {
        "question": "Are overnight (red‑eye) flights available from Seoul to Tokyo?",
        "answer": "Yes, overnight red‑eye flights are available nonstop from Seoul Incheon (ICN) to Tokyo Haneda (HND). Asiana (OZ) operates two daily red‑eyes departing around 9:10 PM and 9:30 PM, and Peach Aviation (MM) runs one daily red‑eye departing at 10:35 PM. These are short flights of roughly two hours, so they land the same night — not the next morning — typically arriving in Tokyo around midnight or just after.",
        "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.",

      "q8": {
        "question": "If I need a connection, what are common layover cities between Seoul and Tokyo?",
        "answer": "Direct flights are plentiful on this short route, but if you need a connection, common layovers include Shanghai Pudong, Beijing Capital, and Taipei Taoyuan. These hubs offer broad connections and efficient transfers, though they add significant travel time compared to nonstop options."
      },
      "q9": {
        "question": "How reliable are on‑time departures on this route from Seoul to Tokyo?",
        "answer": "On-time performance is generally high, but afternoon and evening flights can encounter delays due to air traffic. Early morning departures on Korean Air and Asiana often have the best on-time records."
      },
      "q10": {
        "question": "Which months have the best weather for traveling to Tokyo?",
        "answer": "Late March to early April for cherry blossoms and mild temperatures, or late October to November for pleasant autumn weather and fewer tourists."
      },
      "q11": {
        "question": "What documents should I bring with me to the airport when flying from Seoul to Tokyo?",
        "answer": "Bring a passport valid for the duration of your stay, any required visa or travel authorization, proof of onward or return travel, a payment method for baggage, and any necessary vaccination or health certificates."
      },
      "q12": {
        "question": "Which airport should I use in Tokyo?",
        "answer": "Haneda is closest to central Tokyo and ideal for business and domestic connections, serving full‑service carriers. Narita handles more international long‑haul and low‑cost flights but is farther from the city."
      },
      "q13": {
        "question": "How do I get to Incheon Intl Airport from the city center?",
        "answer": "From downtown Seoul, the fastest and most popular way to reach Incheon International Airport is the AREX Airport Railroad express train, which takes about 43 minutes from Seoul Station and costs around 11,000 KRW. Deluxe airport limousine buses are a convenient alternative, with direct service from major districts like Gangnam and Myeongdong for about 17,000–18,000 KRW, though travel time can be 70–90 minutes depending on traffic. Taxis and ride‑share are available but expensive, typically costing over 70,000 KRW and still subject to highway congestion. Driving and parking is possible, with both short‑term and long‑term lots, but it’s rarely recommended due to high fees and traffic.",
