Nonstop flights typically take 2 hours 25 minutes, with the return leg lasting about 2 hours 30 minutes — a small difference that doesn't meaningfully favor either direction.", "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"]}, "q6": {"question": "Are overnight (red‑eye) flights available from Seoul to Yanji?", "answer": "No overnight red‑eye flights operate from Seoul (ICN) to Yanji (YNJ) — there are no nonstop red‑eyes on this route and no connecting itineraries whose long leg is a red‑eye.", "methodology": "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.", "toolsUsed": ["redeye_flights"]}, "q7": {"question": "Which airlines usually operate this route from Seoul to Yanji?", "answer": "Six airlines fly nonstop from Seoul Incheon to Yanji: Asiana Airlines (15 weekly flights), Korean Air (14 weekly flights), Air China, China Eastern, and China Southern (each daily), plus Jeju Air (6 weekly).
