        "question": "What is the typical flight duration from Guam Island to Seoul?",
        "answer": "The flight from Guam Island to Seoul covers about 2,010 miles and typically takes 4 hours and 50 minutes nonstop. The return leg is about 4 hours and 30 minutes, so the outbound journey is slightly longer.",
        "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 Guam Island to Seoul?",
        "answer": "Yes, there are non‑stop flights from Guam (GUM) to Seoul Incheon (ICN) on Korean Air, Jin Air, and Air Seoul — all three fly daily. Together they offer about 44 weekly departures with flight times around 4 hours 40 minutes, and the return leg is slightly shorter at roughly 4 hours 30 minutes.",
        "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": "From Incheon International Airport, the fastest and most popular way into Seoul is the AREX Airport Railroad, with express trains reaching Seoul Station in about 43 minutes. Commuter AREX trains are a cheaper alternative, while limousine buses serve major districts like Gangnam and Dongdaemun with fares around 17,000–18,000 KRW. Taxis and ride‑share services are available at the terminals, and rental cars can be arranged, though most visitors rely on the train or bus.",
