        "question": "What is the typical flight duration from Columbus to Seoul?",
        "answer": "Columbus to Seoul requires a connection, as there is no nonstop service. The distance is about 6,770 miles. A typical one-stop journey takes approximately 17 to 20 hours total, depending on the layover.",
        "methodology": "Flight times and distances come 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). 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. Distance is the great-circle distance between the two airports, so the actual flown track is typically 2-5% longer.",

        "question": "Are there any direct flights from Columbus to Seoul?",
        "answer": "There are no nonstop flights from Columbus (CMH) to Seoul. The shortest connecting routings typically go through a West Coast hub like San Francisco (SFO) or Seattle (SEA), with total travel time around 16–19 hours including a layover. United, American, and Asiana offer one-stop itineraries via SFO, DFW, JFK, or LGA, with the long-haul leg flown on Boeing 787-9 or Airbus A350-900 aircraft.",
        "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. 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. Aircraft types are taken from the equipment each operating carrier schedules on this route, drawn from published airline timetables and airline equipment schedules in our flight-schedule database. They describe typical scheduled aircraft and can vary with seasonal or day-of-week assignments and last-minute equipment swaps.",

        "question": "What are the ground transportation options in Seoul?",
        "answer": "From Incheon Airport (ICN) to central Seoul, the Airport Railroad Express (AREX) is the most popular and efficient option, offering both an express train to Seoul Station in about 43 minutes and a commuter service that stops at multiple stations. Airport limousine buses provide comfortable, direct service to major hotels and districts, with fares ranging from 8,000 to 18,000 KRW. Taxis and ride-share services are readily available, though more expensive. Car rentals are possible but generally unnecessary given Seoul's excellent public transit. The AREX express train is the fastest and most-used for reaching the city center.",

        "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.",

        "answer": "Incheon is the primary international airport, located about 30 miles west of central Seoul, and serves most global carriers including both SkyTeam and Star Alliance hubs. Gimpo is closer to downtown and handles domestic flights along with some short‑haul Asian routes, making it convenient for regional connections."

        "question": "How do I get to John Glenn Intl Airport from the city center?",
        "answer": "From downtown Columbus, you can take the COTA AirConnect bus, which runs every 30 minutes from the Convention Center to the airport in about 25 minutes for $2.75 — the most popular and affordable option. Taxis are available 24/7 at the ground transportation area and cost around $25 to downtown, while ride‑share services like Uber and Lyft also pick up there. Driving yourself takes about 15 minutes via I‑670 and on‑site parking is available.",
