        "question": "What is the typical flight duration from Hanoi to Seoul?",
        "answer": "A nonstop flight from Hanoi (HAN) to Seoul (ICN) normally takes about 4 hours 10 minutes to 4 hours 30 minutes. With one stop, most itineraries average 8 to 10 hours total travel time, with common layover cities including Hong Kong or Taipei. Return flights from Seoul to Hanoi are often slightly shorter, around 3 hours 50 minutes to 4 hours 10 minutes."

      "q1": {
        "question": "Are there any direct flights from Hanoi to Seoul?",
        "answer": "Yes, Hanoi (HAN) to Seoul (ICN) has abundant non‑stop flights — five airlines operate the route, all daily. VietJet Air, Vietnam Airlines, Korean Air, Asiana Airlines, and Jeju Air together offer about 120 weekly non‑stop departures, with departures spread from early morning to late evening. Korean Air, Asiana, Vietnam Airlines, and VietJet also run overnight red‑eyes departing between 22:50 and 23:50.",
        "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. Aircraft types are taken from the equipment each operating carrier schedules on this route, drawn from published airline timetables and airline equipment schedules in our flight-schedule database. They describe typical scheduled aircraft and can vary with seasonal or day-of-week assignments and last-minute equipment swaps. 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": "Yes, there are visa requirements for travel between Hanoi and Seoul. Vietnamese citizens can travel to South Korea visa-free for up to 45 days if entering through Incheon Airport under the K-ETA program, provided they have a valid e-passport and K-ETA approval. Other nationalities may need a visa or K-ETA depending on their country's agreement with South Korea. For the reverse route, South Korean citizens can enter Vietnam visa-free for up to 45 days. Travelers of other nationalities should check Vietnam's visa requirements based on their citizenship."
      },
      "q3": {
        "question": "What are the ground transportation options in Seoul?",
        "answer": "From Incheon Airport, the fastest way to Seoul is the AREX express train, reaching Seoul Station in about 43 minutes. The commuter AREX train is cheaper and also widely used. Limousine buses serve many city districts with comfortable seats and luggage space, though they take longer and are subject to traffic. Taxis are available but expensive, and ride-share is limited compared to other cities. Car rentals are an option but generally not recommended for city-center travel due to heavy traffic and parking challenges; most travelers use the train or bus.",
