        "question": "What is the typical flight duration from Tokyo to Seoul?",
        "answer": "A nonstop flight from Tokyo (HND) to Seoul (e.g. ICN) typically takes about 2 hours 30 minutes to 2 hours 45 minutes. The return leg is similar. With a layover, total time often extends to 5–7 hours, commonly via cities like Osaka or Fukuoka. Airlines such as Korean Air and Asiana offer consistently fast nonstop service."
      },
      "q1": {
        "question": "Are there any direct flights from Tokyo to Seoul?",
        "answer": "Yes, there are direct nonstop flights from Tokyo Haneda (HND) to Seoul, with service to both Gimpo (GMP) and Incheon (ICN) airports. Five airlines operate these routes: ANA (NH), Korean Air (KE), Japan Airlines (JL), Asiana Airlines (OZ), and Peach Aviation (MM), with flights running daily across all carriers. The HND–GMP route sees the highest frequency — ANA and Korean Air each operate 42 weekly flights, Japan Airlines runs 35, and Asiana offers 28 — while HND–ICN has daily service from Peach, Asiana, and Korean Air.",
        "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, there are visa requirements depending on your nationality. Japanese passport holders can enter South Korea visa-free for short stays (up to 90 days) under the current bilateral agreement, but they must obtain a Korea Electronic Travel Authorization (K-ETA) before departure unless exempt. South Korean nationals do not need a visa to enter Japan for short stays (typically up to 90 days). Travelers of other nationalities should check both South Korea's and Japan's entry rules based on their passport."

      "q3": {
        "question": "What are the ground transportation options in Seoul?",
        "answer": "Seoul is served by two main airports: Incheon International (ICN) and Gimpo International (GMP). From Incheon, the AREX Express train reaches Seoul Station in about 43 minutes and is the fastest and most popular option. The AREX All Stop train takes around 60 minutes and is slightly cheaper. Airport limousine buses connect to major districts in 60 to 90 minutes and are comfortable but subject to traffic. Taxis and ride-share services are available but cost around 50,000 to 70,000 KRW and can take over an hour. From Gimpo, the AREX All Stop train reaches Seoul Station in about 20 minutes, while taxis take roughly 30 minutes. Car rentals are available at both airports but are not recommended for city travel due to heavy traffic and limited parking. Most travelers use the AREX train 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 Haneda (HND) to Seoul (SEL). A connecting option exists with an overnight leg from Narita (NRT) to Ulaanbaatar (UBN) on MIAT Mongolian Airlines departing around 9:30 PM and arriving at 2:05 AM, followed by a long layover and onward flight to Seoul, but no direct overnight service is available on this route.",
        "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": "Which airlines usually operate this route from Tokyo to Seoul?",
        "answer": "Based on schedule data, nonstop flights from Tokyo Haneda (HND) to Seoul are operated by All Nippon Airways (NH), Korean Air (KE), Japan Airlines (JL), Asiana Airlines (OZ), and Peach Aviation (MM). Most of these services fly into Seoul Gimpo (GMP), while some Asiana, Korean Air, and Peach flights serve Incheon (ICN).",

        "question": "If I need a connection, what are common layover cities between Tokyo and Seoul?",
        "answer": "Direct flights between Tokyo and Seoul are plentiful, so a connection is rarely needed. If one is required, common layover cities include Osaka, Fukuoka, or Busan, though they add significant travel time given the short distance. These hubs offer efficient domestic-to-international transfers but are not competitive with nonstop options."
      },
      "q9": {
        "question": "How reliable are on‑time departures on this route from Tokyo to Seoul?",
        "answer": "On‑time reliability is high, as this is a heavily trafficked short‑haul route. Early‑morning flights on Korean Air and Asiana Airlines are particularly punctual, while afternoon services may encounter minor delays due to air traffic or weather."

      },
      "q12": {
        "question": "Which airport should I use in Seoul?",
        "answer": "Incheon is the main international airport, well-connected to Seoul by express train, and serves most full-service carriers. Gimpo is closer to downtown and primarily handles domestic and some short-haul international flights, convenient for business travellers."
      },
      "q13": {
        "question": "How do I get to Haneda Intl Airport from the city center?",
        "answer": "From central Tokyo to Haneda Airport, the Tokyo Monorail and Keikyu Line are fast and popular, taking 15–30 minutes. Limousine buses serve major hotels but are slower. Taxis and rideshares are convenient but expensive, especially late at night. Driving and parking are costly and generally not recommended."
