        "question": "What is the typical flight duration from Seoul to Ryukyu Islands?",
        "answer": "The flight from Seoul to Ryukyu Islands is about 780 miles. The typical nonstop duration is 2 hours and 30 minutes, with the return leg taking 2 hours and 20 minutes, making the outbound slightly longer. Korean Air, Jin Air, T'way Air, Eastar Jet, Jeju Air, and Asiana Airlines all operate daily nonstop service on this route.",
        "methodology": "Flight times and distances come 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). The typical flight time is the median scheduled block time across all carriers on the route, computed the same way in both directions so the difference reflects prevailing winds rather than any change in method. Distance is the great-circle distance between the two airports, so the actual flown track is typically 2-5% longer.",

        "question": "Are there any direct flights from Seoul to Ryukyu Islands?",
        "answer": "Yes, there are direct flights from Seoul Incheon (ICN) to Okinawa (OKA). Six airlines — Korean Air, Jin Air, T'way Air, Eastar Jet, Jeju Air, and Asiana Airlines — operate daily non‑stop service, with Korean Air running twice daily. In total there are about 49 weekly non‑stop flights taking roughly 2.5 hours.",
        "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, flight times and distances for this route come 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). We report the days of the week and the departure times each carrier operates. The typical flight time is the median scheduled block time, given both per carrier and across all carriers on the route; where a schedule does not publish an elapsed time, it is derived from the scheduled departure and arrival times converted to UTC. Outbound and return times are computed by the same method, so the difference between them is directly comparable and reflects prevailing winds rather than any change in derivation. Distance is the great-circle distance between the two specific airports named, so an actual flown track is typically 2-5% longer. Where shown, on-time departure and arrival rates and cancellation rates come from the U.S. Bureau of Transportation Statistics (BTS) Airline On-Time Performance dataset, which covers U.S. domestic routes only; where a typical fare is shown, it comes from the U.S. DOT Airline Origin and Destination Survey (DB1B), a quarterly 10% sample of tickets sold.",

        "answer": "At Naha Airport (OKA), ground transportation to central Okinawa includes taxis, airport shuttles, the Okinawa Urban Monorail (Yui Rail), buses, and rental cars. The Yui Rail monorail is the fastest and most-used option, connecting the airport to central Naha in about 15 minutes, while buses serve wider parts of the island. Taxis offer door-to-door convenience but cost more, and rental cars are popular for exploring beyond the city.",

        "question": "How do I get to Incheon Intl Airport from the city center?",
        "answer": "From central Seoul, the Airport Railroad Express (AREX) and standard subway trains connect to Incheon Intl Airport, while express and limousine buses serve major downtown stops and hotels. Taxis and ride-share services offer door-to-door convenience, and driving to the airport is possible with short- and long-term parking available on site. The AREX express train is often the fastest and most popular choice for city-center departures, while buses are a comfortable and economical alternative; taxis and private cars cost more but provide the most direct access.",
