        "question": "What is the typical flight duration from Seoul to Ryukyu Islands?",
        "answer": "A direct flight from Seoul Incheon (ICN) to Okinawa Naha (OKA) typically takes about 2 hours 15 minutes to 2 hours 30 minutes. If you have a layover, common stops include Tokyo or Osaka, and the total journey can range from 4 to 7 hours depending on the connection time."
      },
      "q1": {
        "question": "Are there any direct flights from Seoul to Ryukyu Islands?",
        "answer": "Yes, there are direct non‑stop flights from Seoul Incheon (ICN) to Okinawa (OKA). Six airlines operate daily service — Korean Air, Jin Air, T'way Air, Eastar Jet, Jeju Air, and Asiana Airlines — with Korean Air flying twice daily and the others once daily, for a total of about 49 weekly departures. All flights are daily, so you can fly any 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. 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": "Are there visa requirements to travel from Seoul to Ryukyu Islands?",
        "answer": "Yes, visa requirements apply for travel between Seoul and the Ryukyu Islands. South Korean nationals can enter Japan visa‑free for short stays (typically up to 90 days) for tourism or business. Japanese nationals can enter South Korea visa‑free for up to 90 days under the visa waiver agreement. Travelers of other nationalities should check Japan’s visa policy based on their citizenship, as a visa may be required before travel. For the return from Japan to South Korea, the same rules apply: Japanese citizens enjoy visa‑free access, while other nationals must meet South Korea’s entry requirements, which may include a visa or K‑ETA authorization depending on nationality."

        "question": "What are the ground transportation options in Ryukyu Islands?",
        "answer": "Naha Airport (OKA) is only about 4 km (2.5 miles) west of Naha city center, and the Yui Rail monorail is the most-used and fastest option, connecting the airport to the city in roughly 10–15 minutes. Taxis are readily available outside the terminal for a direct, more private ride, while ride-share services are limited in Okinawa compared to mainland Japan. Rental cars are popular for exploring the island beyond Naha, and several agencies have counters at the airport. Airport shuttle services also run to major hotels on the main island, offering a middle ground between cost and convenience.",

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

        "question": "Which airport should I use in Ryukyu Islands?",
        "answer": "Naha Airport is the only airport serving the Ryukyu Islands. It is located in the city of Naha on Okinawa Island, close to the city center and popular attractions like Kokusai Street."
      },
      "q13": {
        "question": "How do I get to Incheon Intl Airport from the city center?",
        "answer": "From central Seoul, the fastest and most popular way to reach Incheon Airport is the AREX express train, which takes about 43 minutes nonstop from Seoul Station. More affordable commuter (all-stop) AREX trains and frequent airport limousine buses also serve various city districts, with buses being convenient if you're near a stop. Taxis and ride‑shares offer door‑to‑door service but are the priciest option, while driving yourself is possible with both short‑term and long‑term parking available at the airport.",
