        "question": "What is the typical flight duration from Madrid to Chicago?",
        "answer": "The flight from Madrid to Chicago is about 4,190 miles. Nonstop service takes around 9 hours 40 minutes eastbound, with the return leg back to Madrid about 8 hours 5 minutes — roughly 1 hour 35 minutes shorter thanks to prevailing tailwinds.",
        "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 Madrid to Chicago?",
        "answer": "Yes, Iberia and American Airlines both fly nonstop from Madrid to Chicago O'Hare, each with 14 weekly flights operating daily. Iberia typically departs around 11:35 AM or noon, while American departs around 1:35 PM or 4:40 PM; the flight takes about 9 hours and 40 minutes on average.",
        "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.",

However, an electronic travel authorisation known as ESTA must be obtained before travel.\n\nThis is general guidance to help you plan, not official immigration advice — entry rules can change and can depend on your nationality and circumstances, so please confirm the current requirements with the relevant embassy or official government source before you travel.",

        "answer": "Chicago O'Hare offers several ground transportation options to the city center, with the CTA Blue Line being the most-used and most economical choice, providing 24-hour train service directly from the airport to downtown in about 40 minutes. Taxis, rideshares, and limos are readily available and offer the fastest door-to-door convenience, typically taking 30-45 minutes depending on traffic, while Metra commuter rail and Pace buses serve suburban destinations. Rental cars are accessible via a shuttle to the Multi-Modal Facility, and airport shuttles and regional buses connect to the city and surrounding areas. The Blue Line is the most popular for solo travelers on a budget, but rideshare or taxi is often preferred for speed, especially with luggage or a group.",
