        "question": "What is the typical flight duration from Jeju Island to Seoul?",
        "answer": "A nonstop flight from Jeju (CJU) to Seoul Gimpo (GMP) typically takes about 1 hour 5 minutes to 1 hour 15 minutes. The return flight is similar. There are no common layovers on this domestic route, as direct flights are the norm. Multiple airlines operate this route with similar flight times."
      },
      "q1": {
        "question": "Are there any direct flights from Jeju Island to Seoul?",
        "answer": "There are abundant non‑stop flights from Jeju (CJU) to Seoul Gimpo (GMP), operated daily by Asiana Airlines (OZ), Korean Air (KE), Jeju Air (7C), Eastar Jet (ZE), Jin Air (LJ), Air Busan (BX), and T'way Air (WE), with departures spread throughout the day from early morning to late evening. The three largest carriers — Asiana, Korean Air, and Jeju Air — each run around 256 weekly flights, while even the smallest carrier, T'way, offers daily service, making this one of the world's busiest domestic air routes.",
        "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.",

      "q2": {
        "question": "Are there visa requirements to travel from Jeju Island to Seoul?",
        "answer": "This route is entirely within South Korea, so no international visa is required for the flight itself. However, if you are a foreign national currently on Jeju Island under its visa-free policy, traveling to mainland Seoul may require a valid Korean visa, as the Jeju visa-free entry does not automatically permit travel to other parts of the country. Korean nationals and foreign residents with valid domestic status can travel freely."
      },
      "q3": {
        "question": "What are the ground transportation options in Seoul?",
        "answer": "Since your flight arrives at Gimpo International Airport (GMP) in Seoul, you are already close to the city center. The most efficient and widely used option is the AREX Express train, which connects Gimpo to Seoul Station in about twenty-five minutes. The Seoul Metropolitan Subway lines 5 and 9 also serve the airport, offering convenient access to various districts, though they take slightly longer. Taxis are readily available and provide a comfortable, door-to-door service, with the ride to central areas taking around thirty to forty minutes depending on traffic. Ride-share services like Kakao T are also popular and easy to use. Car rentals are available but not recommended for city travel due to heavy traffic and limited parking. Most travelers opt for the AREX or subway for their speed, reliability, and cost-effectiveness."

        "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.",
