The typical flight time is the median scheduled block time across all carriers on the route, computed the same way in both directions so the difference reflects prevailing winds rather than any change in method.

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. Where a median fare is shown for a carrier, it reflects the real fares Priceline users found on this route in the last 72 hours. 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": [ "route_airlines", "flight_schedule" ] }, "q3": { "question": "What are the ground transportation options in Seoul?", "answer": "From Incheon Airport (ICN) to central Seoul, the AREX express train is the fastest and most-used option, reaching Seoul Station in about 43 minutes for 8,000 won.

Airport limousine buses serve many city districts with fares ranging from 16,000 to 18,000 won, and taxis are available but cost significantly more.

Incheon is the primary international gateway, located about 48 km west of central Seoul, serving most full‑service airlines and global alliances.

Taxis and ride‑share provide door‑to‑door convenience at a higher cost, while driving and parking at the on‑island lot is straightforward for those with a car.
