        "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 10 minutes. Flights to Incheon (ICN) are slightly longer, around 1 hour 15 minutes. There are no practical layover options on this domestic route."

        "question": "Are there any direct flights from Jeju Island to Seoul?",
        "answer": "Yes, there are plenty of non‑stop flights from Jeju Island (CJU) to Seoul. Seven airlines — Asiana (OZ), Korean Air (KE), Jin Air (LJ), Jeju Air (7C), Eastar Jet (ZE), Air Busan (BX), and WE — together operate over 1,000 weekly flights between CJU and Gimpo (GMP), all running daily. The route is one of the busiest in the world, with departures spread across the day from early morning until late 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. 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 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": "What are the ground transportation options in Seoul?",
        "answer": "From Incheon Airport, the fastest and most popular way to central Seoul is the AREX express train, reaching Seoul Station in about 43 minutes. Comfortable airport limousine buses serve major districts like Gangnam and Dongdaemun, with fares around ₩17,000–₩18,000. Taxis and ride-share are available but slower and pricier due to traffic. Car rentals are an option, though driving in Seoul is challenging for visitors. The AREX express train is the most used for its speed and reliability.",
