        "question": "What is the typical flight duration from Chicago to Copenhagen?",
        "answer": "The flight from Chicago to Copenhagen is about 4,260 miles and typically takes 8 hours 30 minutes nonstop. The return leg from Copenhagen to Chicago averages 9 hours 15 minutes, making the westbound journey about 45 minutes longer due to prevailing winds.",
        "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 Chicago to Copenhagen?",
        "answer": "SAS flies non‑stop from Chicago O'Hare (ORD) to Copenhagen (CPH) daily, with up to 22 flights per week. Departures are clustered in the evening around 7:15–8:20 PM, and the flight takes roughly 8½ hours eastbound.",
        "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.",

        "answer": "Copenhagen Airport offers several solid ground transportation options to the city center. The metro is the fastest and most-used choice, running every 4–6 minutes during the day and reaching Nørreport Station in about 15 minutes from Terminal 3. InterCity trains also connect the airport to central Copenhagen from Tracks 1 and 2, and multiple bus lines serve the route, including FlixBus and regional services. Taxis are available at the terminals, though they are typically more expensive than rail options. Rental cars are offered by Avis, Sixt, Europcar, Hertz, Budget, and Enterprise at the Car Rental Centre, plus the app-based SwipNgo at Terminal 3.",

        "question": "How do I get to Dupage County from the city center?",
        "answer": "From downtown Chicago to O'Hare, the CTA Blue Line 'L' train is the fastest and most popular option, running 24 hours and reaching the airport in about 40 minutes for a low fare. Metra's North Central Service also connects Union Station to the airport on weekdays via the O'Hare Transfer Station, and Pace suburban buses serve the terminals from surrounding areas. Taxis, limos, and rideshare services are readily available and cost more than transit, while driving offers several parking choices including hourly, daily, and economy lots. The Blue Line is generally the cheapest and most reliable way to get there without a car.",
