        "question": "What is the typical flight duration from Jeju Island to Cheongju-si?",
        "answer": "The flight from Jeju Island to Cheongju-si covers about 229 miles. The typical nonstop flight time is 1 hour 10 minutes, and the return leg takes the same amount of time.",
        "methodology": "Flight times and distances come 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). The typical flight time is the median scheduled block time across all carriers on the route, computed the same way in both directions so the difference reflects prevailing winds rather than any change in method. Distance is the great-circle distance between the two airports, so the actual flown track is typically 2-5% longer.",

        "question": "Are there any direct flights from Jeju Island to Cheongju-si?",
        "answer": "Yes, there are direct flights from Jeju Island to Cheongju-si, operated by five airlines — Korean Air, Jeju Air, Asiana Airlines, Jin Air, and Eastar Jet — all running daily. Together they offer about 178 weekly nonstop flights, with departures spread throughout the day from early morning to late evening and a typical flight time of about 70 minutes.",
        "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. Carrier service, flight times and distances for this route come 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). We report the days of the week and the departure times each carrier operates. The typical flight time is the median scheduled block time, given both per carrier and across all carriers on the route; where a schedule does not publish an elapsed time, it is derived from the scheduled departure and arrival times converted to UTC. Outbound and return times are computed by the same method, so the difference between them is directly comparable and reflects prevailing winds rather than any change in derivation. Distance is the great-circle distance between the two specific airports named, so an actual flown track is typically 2-5% longer. Where shown, on-time departure and arrival rates and cancellation rates come from the U.S. Bureau of Transportation Statistics (BTS) Airline On-Time Performance dataset, which covers U.S. domestic routes only; where a typical fare is shown, it comes from the U.S. DOT Airline Origin and Destination Survey (DB1B), a quarterly 10% sample of tickets sold.",

        "question": "What are the ground transportation options in Cheongju-si?",
        "answer": "Ground transportation from Cheongju International Airport to the city center is fairly limited: there is a train station at the airport on the Chungbuk Line, but service is infrequent and it is not a main line, while the KTX high-speed train stops at Osong Station outside the city instead. Buses are the most practical public option, with roughly 13 daily express and conventional buses to Seoul's Central City Terminal plus four from COEX in southern Seoul, though local city buses are not detailed. Taxis and rental cars are available, with a parking lot directly opposite the terminal, but ride-share services like Uber are not mentioned. Driving or taking a taxi is likely the fastest door-to-door option given the limited rail schedule, while buses are the most commonly used public transit link.",

All carriers operate daily service, with Korean Air offering the most frequent schedule. Median fares are not available for this route.",

        "question": "Which airport should I use in Cheongju-si?",
        "answer": "Cheongju International Airport is the only airport serving the city, located about 10 km northeast of downtown. It handles domestic flights and limited international services, primarily by low‑cost carriers like Jeju Air and T'way Air."

        "question": "How do I get to Jeju Intl Airport from the city center?",
        "answer": "From downtown Jeju City, the most popular and fastest way to reach Jeju International Airport is by taxi or ride-share, since the airport sits right in the city and the trip is short. Public city buses also run frequently from central areas to the airport and are the cheapest option. Shuttle buses are limited, and driving yourself is possible with airport parking available, though a taxi is generally more convenient for most travelers.",
