        "question": "What is the typical flight duration from Seoul to Hanoi?",
        "answer": "A direct flight from Seoul (ICN) to Hanoi (HAN) typically takes 4 hours 30 minutes to 5 hours. The return flight often takes slightly longer, around 5 hours to 5 hours 30 minutes, due to prevailing winds. Flights with a layover, most commonly via Hong Kong or Taipei, usually range from 8 to 12 hours total travel time. Korean Air, Asiana Airlines, and VietJet Air are among the faster options on the direct route."
      },
      "q1": {
        "question": "Are there any direct flights from Seoul to Hanoi?",
        "answer": "Yes, there are nonstop flights from Seoul (ICN) to Hanoi (HAN) operated by five airlines — Asiana (OZ), Vietnam Airlines (VN), VietJet Air (VJ), Korean Air (KE), and Jeju Air (7C) — all running daily. Together they offer around 11 daily departures spread from early morning (06:25) through late evening (20:40).",
        "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. 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.",
