The return leg from Seoul to Hanoi is longer at 4 hours and 50 minutes due to prevailing winds.", "methodology": "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.", "toolsUsed": ["flight_schedule"]}, "q1": {"question": "Are there any direct flights from Hanoi to Seoul?", "answer": "Five airlines fly nonstop from Hanoi to Seoul: VietJet Air, Vietnam Airlines, Korean Air, Asiana Airlines, and Jeju Air, all operating daily.
