      "q1": {
        "question": "Are there any direct flights from Jeju Island to Cheongju-si?",
        "answer": "Yes, there are frequent non‑stop flights from Jeju (CJU) to Cheongju (CJJ). Five airlines serve the route: Korean Air (52 weekly), Jeju Air (42 weekly), Asiana Airlines (42 weekly), Jin Air (28 weekly), and Eastar Jet (14 weekly), and all five operate daily service, so flights are available every day of the week.",
        "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": "What are the ground transportation options in Cheongju-si?",
        "answer": "Cheongju International Airport is located about 10 kilometers from the city center. The most convenient and commonly used option is the express bus, which connects the airport directly to the Cheongju Bus Terminal in the city center in about 20 to 30 minutes. Local city buses also serve the airport but are slower and less direct. Taxis are readily available outside the terminal, offering a quick and comfortable ride to downtown in approximately 20 minutes. Ride-share apps are not widely used in Cheongju. Car rental counters are present at the airport for travelers needing their own vehicle, though this is less common for short city trips. Most passengers use the express bus for its balance of cost and efficiency."
