        "question": "What is the typical flight duration from Ryukyu Islands to Seoul?",
        "answer": "A direct flight from Naha, Okinawa (OKA) to Seoul Incheon (ICN) typically takes about 2 hours and 30 minutes. Flights with one stop, often via Tokyo or Osaka, can extend total travel time to around 5 to 7 hours depending on layover duration. The return flight from Seoul to Okinawa is similar in duration, usually around 2 hours and 40 minutes nonstop. Airlines like Korean Air and Asiana offer direct service, while low-cost carriers may provide competitive times with fewer frills."

        "question": "Are there any direct flights from Ryukyu Islands to Seoul?",
        "answer": "Yes, there are nonstop flights from Okinawa (OKA) to Seoul Incheon (ICN), with six airlines operating daily service: Korean Air (twice daily at 12:50 and 18:05), Jin Air (13:15), T'way Air (14:35), Eastar Jet (15:00), Jeju Air (16:45), and Asiana Airlines (18:00). All run daily, giving you roughly six to seven nonstop departures 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": "Are there visa requirements to travel from Ryukyu Islands to Seoul?",
        "answer": "Yes, there are visa requirements. For Japanese nationals, South Korea currently allows visa-free entry for short stays (typically up to 90 days for tourism, but entry rules can change; K-ETA may be required). For South Korean nationals, Japan allows visa-free short stays. For nationals of other countries, a visa or travel authorization may be required for either country. Always verify the latest entry rules before travel, as policies can change with little notice."

        "question": "What are the ground transportation options in Seoul?",
        "answer": "From Incheon International Airport (ICN), the AREX Express train is the fastest option, reaching Seoul Station in about 43 minutes non-stop.
