        "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.",

        "answer": "From Incheon International Airport to Seoul, the main ground transportation options are the Airport Railroad express train, limousine buses, taxis, and private cars. The AREX train is fast and reliable, while limousine buses offer wider coverage for areas not directly on the rail line, with direct bus fares to Seoul at 17,000 KRW for adults. Taxis are widely available with base fares around 4,800 KRW for standard taxis, but a 20-30% surcharge applies to Seoul taxis leaving the airport. Most travelers use the Airport Railroad train as the most popular and efficient option for reaching central Seoul. Ride-sharing is not a prominent option here, and car rentals are available but less commonly used for airport transfers.",

Connecting itineraries whose long leg is an overnight red-eye are available: the long-haul segment from San Francisco (SFO) to Seoul Incheon (ICN) on United departs at 11:55 PM and arrives at 4:20 AM, connecting via SFO with a layover of about 2 hours 41 minutes on the outbound United flight from Columbus.",
        "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.",

Common one-stop routings include United via San Francisco, American via Dallas/Fort Worth, and Asiana Airlines via New York (JFK or LGA), with United and American each offering several daily connections. Delta also appears on some Asiana codeshare legs, while Alaska Airlines offers a less frequent option via Seattle.

        "question": "Which airport should I use in Seoul?",
        "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."
      },
      "q13": {
        "question": "How do I get to John Glenn Intl Airport from the city center?",
        "answer": "From downtown Columbus, the Central Ohio Transit Authority (COTA) runs a public bus directly to John Glenn Columbus International Airport, while shuttle buses, ride-share services like Uber and Lyft, and taxis all provide door-to-door convenience. Driving yourself is also an option, with on-airport parking plus cheaper satellite lots connected by free shuttle. Ride-share or a taxi is typically the fastest choice, and driving is most popular for those who need a car at the airport, though public transit is the most budget-friendly.",
