        "question": "What is the typical flight duration from Ryukyu Islands to Seoul?",
        "answer": "A direct flight from Naha (OKA) to Seoul Incheon (ICN) typically takes about 2 hours and 30 minutes to 2 hours and 50 minutes. Flights with one stop, often via Tokyo, can extend the journey to 5 to 8 hours depending on layover duration. The return flight from Seoul to Okinawa is generally similar, around 2 hours and 40 minutes nonstop. Korean Air and Asiana frequently operate faster direct services on this route."
      },
      "q1": {
        "question": "Are there any direct flights from Ryukyu Islands to Seoul?",
        "answer": "Yes, there are multiple daily non‑stop flights from Okinawa (OKA) to Seoul (ICN) on Korean Air, Jin Air, T'way Air, Eastar Jet, Jeju Air, and Asiana Airlines, all operating daily. Korean Air runs twice daily (around 12:50 PM and 6:05 PM), while the others each offer one daily departure between early afternoon and early evening. All six carriers serve the route 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. 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.",

      "q2": {
        "question": "Are there visa requirements to travel from Ryukyu Islands to Seoul?",
        "answer": "Yes, visa requirements depend on your nationality. Since the Ryukyu Islands (Okinawa) are part of Japan, you are traveling from Japan to South Korea. Japanese passport holders can enter South Korea visa‑free for short stays (typically up to 90 days) under the K‑ETA system; from April 1, 2023, to December 31, 2025, Japanese nationals are temporarily exempt from the K‑ETA requirement. South Korean nationals do not need a visa to enter Japan. Travelers of other nationalities should check both Japan’s exit rules and South Korea’s entry requirements based on their passport."

      "q3": {
        "question": "What are the ground transportation options in Seoul?",
        "answer": "Flights from Okinawa typically arrive at Incheon International Airport (ICN), with some low-cost carriers landing at Gimpo International Airport (GMP). From Incheon, the non-stop AREX Express train reaches Seoul Station in about 43 minutes, while the all-stop AREX takes around 66 minutes. Airport limousine buses serve major districts and hotels, taking 60 to 90 minutes depending on traffic. Taxis are available but expensive, with a trip to central Seoul costing around 50,000 to 70,000 KRW and taking 60 to 90 minutes. Ride-share services like Kakao T are widely used but function similarly to taxis. Car rentals are available but not recommended for city travel due to heavy traffic and limited parking. From Gimpo, the AREX and subway lines connect to central Seoul in about 20 to 30 minutes. Most travelers use the AREX train for its speed, reliability, and reasonable cost."

        "question": "Are overnight (red‑eye) flights available from Ryukyu Islands to Seoul?",
        "answer": "There are no nonstop red-eye flights from Okinawa (OKA) to Seoul (SEL). A connecting itinerary with an overnight leg does appear in the schedule data — it departs Okinawa at 9:00 PM on EH, arrives at Tokyo Haneda at 11:30 PM, then connects to a Seoul-bound NH flight after a long layover — but that is not a true red-eye to Seoul and the Seoul arrival is not the next morning.",
        "methodology": "Red-eye flights are identified from scheduled local departure and arrival times in our flight-schedule database — built from published airline timetables and official schedule data, including U.S. Department of Transportation records for domestic routes — flagging services that depart late at night and arrive the following morning; for connecting itineraries the red-eye is based on the timing of the overnight long-haul leg.",

        "answer": "Nonstop flights from Okinawa (OKA) to Seoul (ICN) are operated by Korean Air, Jin Air, T'way Air, Eastar Jet, Jeju Air, and Asiana Airlines, with multiple daily departures available. These carriers offer daily service, with departure times ranging from early afternoon to evening.

        "question": "If I need a connection, what are common layover cities between Ryukyu Islands and Seoul?",
        "answer": "Common layover cities include Tokyo (Narita or Haneda), Osaka (Kansai), and Taipei (Taoyuan). Tokyo offers the highest frequency and onward connections to Seoul, while Osaka provides a shorter detour. Taipei can be efficient and often allows visa‑free transit for many nationalities, though total travel time may be slightly longer."

      "q9": {
        "question": "How reliable are on‑time departures on this route from Ryukyu Islands to Seoul?",

      },
      "q12": {
        "question": "Which airport should I use in Seoul?",
        "answer": "Incheon handles nearly all international flights and is the primary gateway. Gimpo serves domestic and select regional routes, including to Japan, and is closer to central Seoul, making it convenient for short-haul trips."
      },
      "q13": {
        "question": "How do I get to Naha Airport from the city center?",
        "answer": "From downtown Naha to Naha Airport, the Okinawa Urban Monorail (Yui Rail) takes about 10–15 minutes and is the cheapest option. Taxis are faster, around 10 minutes, but cost more. Limousine buses serve major hotels, while driving and parking are available but less common."

The airport has a nursing room and a small kids’ play area near the domestic gates.
