        "question": "What is the typical flight duration from Tokyo to Seoul?",
        "answer": "A nonstop flight from Tokyo (HND) to Seoul (ICN) typically takes about 2 hours 30 minutes, while the return leg is slightly shorter at around 2 hours 10 minutes due to prevailing winds. With a layover, total travel time usually ranges from 5 to 7 hours depending on the connection."

      "q2": {
        "question": "Are there visa requirements to travel from Tokyo to Seoul?",
        "answer": "Yes, visa requirements apply for flights from Tokyo to Seoul depending on nationality. Japanese citizens do not need a visa for South Korea for short-term tourism or business for up to 90 days (K-ETA is currently exempt for Japanese nationals through December 31, 2025). South Korean citizens do not need a visa for Japan for short stays (up to 90 days). Other nationals should check the specific visa policies of South Korea and Japan based on their citizenship."

      "q3": {
        "question": "What are the ground transportation options in Seoul?",
        "answer": "From Incheon International Airport (ICN), the fastest and most-used option to reach central Seoul is the AREX express train, which runs nonstop to Seoul Station in about 43 minutes. The all-stop commuter train is a cheaper rail alternative, and the airport limousine buses serve key districts like Gangnam and Dongdaemun with fares around 17,000–18,000 KRW. Taxis and ride‑hailing services are available but take longer in traffic; rental cars are an option though rarely used for city transfers due to excellent public transit.",

        "question": "Are overnight (red‑eye) flights available from Tokyo to Seoul?",
        "answer": "No overnight (red-eye) flights operate on the Tokyo Haneda to Seoul route — neither nonstop nor connecting itineraries with a red-eye long leg were found in the schedule.",
        "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.",

      "q7": {
        "question": "Which airlines usually operate this route from Tokyo to Seoul?",
        "answer": "Nonstop flights from Tokyo Haneda to Seoul are operated by All Nippon Airways, Korean Air, Japan Airlines, Asiana Airlines, and Peach Aviation. Most service goes to Gimpo, where ANA and Korean Air each offer 42 weekly flights, Japan Airlines has 35, and Asiana 28. Asiana, Korean Air, and Peach also fly to Incheon, though less frequently — 7 or 8 flights a week. Median fares are not available for these carriers.",
        "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.",

      "q8": {
        "question": "If I need a connection, what are common layover cities between Tokyo and Seoul?",
        "answer": "Direct flights are plentiful and typically take 2–3 hours, so connections are rarely needed. If you must connect, common hubs include Osaka, Fukuoka, Busan, and Beijing, though they add significant time."
      },
      "q9": {
        "question": "How reliable are on‑time departures on this route from Tokyo to Seoul?",
        "answer": "On‑time performance is generally good, though afternoon flights can face minor delays due to air traffic. Early morning departures on Japan Airlines and Korean Air tend to be the most punctual."
      },
      "q10": {
        "question": "Which months have the best weather for traveling to Seoul?",

        "answer": "Bring a passport valid for the duration of your stay, any required visa or K-ETA, proof of onward or return travel, a payment method for baggage and any vaccination certificates if applicable."
      },
      "q12": {
        "question": "Which airport should I use in Seoul?",
        "answer": "Seoul has two airports: Incheon International Airport is the main gateway for international flights, located about 48 km west of central Seoul, serving major full-service carriers like Korean Air and Asiana. Gimpo International Airport is closer to downtown, roughly 15 km away, and primarily handles domestic flights along with some regional international routes to nearby countries like Japan and China, making it convenient for short-haul travel."
      },
      "q14": {
        "question": "Are there hotels or sleeping facilities at Seoul airport?",
        "answer": "Seoul Incheon Airport (ICN) has a transit hotel airside on the 4th floor of Terminal 1, available in 6-hour blocks for international transfer passengers. There is also an ibis Styles Ambassador hotel connected to the airport with shuttle service. Both terminals offer designated rest zones with reclining loungers and armrest-free benches for sleeping.",

Most of these jets offer Wi-Fi and seatback entertainment, though specific availability varies by carrier.",
