        "question": "What is the typical flight duration from Tokyo to Busan?",
        "answer": "A direct flight from Tokyo (NRT) to Busan (PUS) typically takes about 2 hours 15 minutes. Most flights on this route are nonstop, operated by airlines like Korean Air and Asiana, with similar flight times. Return flights are roughly the same duration. Layover flights, often via Seoul (ICN), can extend total travel time to 4–6 hours."
      },
      "q1": {
        "question": "Are there any direct flights from Tokyo to Busan?",
        "answer": "Yes, there are direct nonstop flights from Tokyo Narita (NRT) to Busan (PUS) operated by Korean Air, Air Busan, Jin Air, and Jeju Air — four airlines in total. All four carriers fly the route daily, with multiple departures throughout the day from late morning to evening.",
        "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. 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 Tokyo to Busan?",
        "answer": "Yes, visa requirements apply for travel from Tokyo, Japan to Busan, South Korea. Japanese nationals can enter South Korea visa-free for short stays (typically up to 90 days) under a visa waiver agreement. South Korean nationals do not need a visa to enter Japan for short stays. Travelers of other nationalities should check both Japan's exit requirements and South Korea's entry rules. For example, many Western passport holders can enter South Korea visa-free for tourism, but some nationalities require a visa or Korea Electronic Travel Authorization (K-ETA). Always verify based on your specific citizenship before travel."

        "question": "What are the ground transportation options in Busan?",
        "answer": "From Gimhae International Airport (PUS) to Busan city center, the most efficient option is the Busan-Gimhae Light Rail Transit, which connects to the Busan Metro system. The light rail takes about 30 minutes to reach Sasang Station, where you can transfer to Metro Line 2 or 3 to reach central areas like Seomyeon in about 15-20 more minutes. Limousine buses also run to major hotels and districts, taking around 40-60 minutes depending on traffic. Taxis are readily available and take about 30-40 minutes to central Busan, costing approximately 25,000-35,000 KRW. Ride-share apps are limited, with Kakao Taxi being the primary app-based hailing option. Car rentals are available but not recommended for city travel due to heavy traffic and limited parking. The light rail combined with the metro is the most used and cost-effective option for most travelers."

        "question": "Are overnight (red‑eye) flights available from Tokyo to Busan?",

      },
      "q13": {
        "question": "How do I get to Narita Intl Airport from the city center?",
