        "question": "What is the typical flight duration from Da Nang to Seoul?",
        "answer": "Flights from Da Nang to Seoul cover about 1,850 miles. Nonstop flights typically take 4 hours 35 minutes outbound, while the return leg averages 5 hours 0 minutes — roughly 25 minutes longer heading back due to prevailing winds.",
        "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 Da Nang to Seoul?",
        "answer": "Yes, there are plenty of nonstop flights from Da Nang to Seoul. Eleven airlines fly the route daily — including VietJet, Korean Air, Asiana, Vietnam Airlines, T'way, Jeju Air, and several others — with a combined total of around 163 weekly flights, most operating every day and a few on four or five days a week. The flight takes about 4½ hours on average.",
        "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.",

        "question": "What are the ground transportation options in Seoul?",
        "answer": "From Incheon International Airport, the two most practical ways into Seoul are the Airport Railroad Express (AREX) train and the airport limousine buses, with the train being the fastest and most used option for most travelers. Taxis are available at designated ranks at both terminals, with standard, deluxe, and international flat-fare options, though they are slower than the train during peak traffic. Ride-share services are not widely used in South Korea, and car rentals are available but generally unnecessary for city-center travel due to Seoul's excellent public transit. The AREX express train connects to Seoul Station in about 43 minutes, while the all-stop commuter train is cheaper but takes longer. Airport limousine buses serve many hotels and neighborhoods across Seoul for around 17,000 KRW one-way, offering a comfortable alternative with luggage assistance.",

        "answer": "Yes, overnight red‑eye flights operate nonstop from Da Nang to Seoul Incheon. VietJet Air offers the most with 21 weekly departures around 22:45–23:45, Korean Air flies twice nightly at roughly 22:55 and 23:20, Asiana Airlines departs near 23:00–23:05, Thai Vietjet Air leaves at 22:40, Vietnam Airlines at 23:30, and Air Premia has four weekly red‑eyes at 22:45 on Wednesdays, Thursdays, Saturdays, and Sundays. These are late‑evening departures that land in Seoul the same night or in the very early hours.",
        "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.",

        "question": "Which airport should I use in Seoul?",
        "answer": "Incheon is the primary international gateway, serving most full‑service and low‑cost airlines, and is well‑connected to central Seoul by express train and bus. Gimpo handles mostly domestic and short‑haul regional flights and is closer to downtown, but it has very limited international service from Da Nang."
      },
      "q13": {
        "question": "How do I get to Da Nang Intl Airport from the city center?",
        "answer": "Da Nang International Airport is located just a few kilometers south of the city center, making it easily reachable by taxi or ride-share, which are generally the fastest and most popular options, taking about 10–15 minutes and costing more than public transport. Public buses and airport shuttle buses run from central Da Nang to the airport, offering a much cheaper alternative with a journey of roughly 20–30 minutes, though schedules can be less frequent. Driving yourself is possible with airport parking available, but it is usually unnecessary given the short distance and affordable taxi fares.",
