On the return, Tokyo to Seoul usually takes 2 hours 40 minutes, a difference of 10 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 Seoul to Tokyo?", "answer": "Yes, nonstop flights from Seoul Incheon (ICN) to Tokyo (TYO) are plentiful, with daily service to both Narita (NRT) and Haneda (HND) on Korean Air, Asiana, Jin Air, Jeju Air, T'way Air, Eastar Jet, Air Seoul, and several others. Most carriers operate daily, though Ethiopian Airlines flies ICN–NRT six days a week (all except Tuesday), Air Premia does the same six days a week, and a handful like ZIPAIR, Thai Vietjet, and Peach serve the route daily. In total there are over 300 weekly nonstop departures across the two Tokyo airports.", "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).
