        "question": "What is the typical flight duration from Hanoi to Seoul?",
        "answer": "A direct flight from Hanoi (HAN) to Seoul Incheon (ICN) typically takes around 4 hours 10 minutes to 4 hours 30 minutes. The return flight from Seoul to Hanoi is often slightly shorter, averaging about 4 hours 5 minutes to 4 hours 20 minutes, due to prevailing winds. Flights with a layover, commonly via Hong Kong or Taipei, can extend total travel time to 7–10 hours or more. Korean Air and Vietnam Airlines often offer the fastest direct service."
      },
      "q1": {
        "question": "Are there any direct flights from Hanoi to Seoul?",
        "answer": "Yes, there are nonstop flights from Hanoi (HAN) to Seoul Incheon (ICN), operated by five airlines: VietJet Air (VJ), Vietnam Airlines (VN), Korean Air (KE), Asiana Airlines (OZ), and Jeju Air (7C). All five carriers run daily service, with multiple departure times throughout the day including morning, afternoon, and late-evening options. Korean Air and Asiana each offer four daily departures, Vietnam Airlines and VietJet Air each have four daily flights, and Jeju Air operates two daily flights, giving travelers frequent nonstop choices on this route.",
        "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.",

        "question": "Are there visa requirements to travel from Hanoi to Seoul?",
        "answer": "Yes — visa requirements depend on your nationality. Vietnamese citizens generally need a visa to enter South Korea, though some short-term visa-free programs (like for Jeju Island or transit) exist under specific conditions. South Korean citizens visiting Vietnam can enter visa-free for up to 45 days as of August 15, 2023. Nationals of other countries should check both South Korea's K-ETA or visa rules and Vietnam's visa policies, as requirements vary. Always verify the latest rules before travel."

      "q3": {
        "question": "What are the ground transportation options in Seoul?",
        "answer": "From Incheon International Airport (ICN) to central Seoul, the AREX Express train reaches Seoul Station in about forty-three minutes nonstop and is highly reliable. The AREX All-Stop train is cheaper and takes around sixty minutes, stopping at several stations. Airport limousine buses serve major districts and hotels, offering convenience with luggage but are subject to traffic, taking sixty to ninety minutes. Taxis are available, with standard taxis being relatively affordable and international taxis offering English-speaking drivers, though travel time varies with traffic. Ride-share services like Kakao T operate but function as taxi hailing. Car rentals are available but not recommended for central Seoul due to congestion and costly parking. Most travelers use the AREX Express or All-Stop trains for their speed and value."
