        "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. Aircraft types are taken from the equipment each operating carrier schedules on this route, drawn from published airline timetables and airline equipment schedules in our flight-schedule database. They describe typical scheduled aircraft and can vary with seasonal or day-of-week assignments and last-minute equipment swaps.",

        "question": "What are the ground transportation options in Jeju Island?",
        "answer": "Jeju International Airport is located close to Jeju City, just a few kilometers from the center. Buses are the primary public transportation option, with an extensive network of city and intercity buses serving major areas. The limousine bus route 600 connects the airport to the Jungmun tourist complex and Seogwipo, while city buses like the 100, 200, and 500 serve Jeju City center. Taxis are readily available and relatively affordable for short trips within the city. Ride-share services are limited, as local apps like Kakao T are more commonly used. Car rentals are extremely popular on Jeju Island due to limited public transport outside urban areas and the flexibility needed for exploring the island’s attractions. Most visitors rent a car from the airport, but for reaching Jeju City center specifically, buses and taxis are the most convenient options."
