        "question": "What is the typical flight duration from Belgrade to Chicago?",
        "answer": "The flight from Belgrade to Chicago is about 4,990 miles. Nonstop service on Air Serbia typically takes 10 hours and 55 minutes eastbound, with the return leg shorter at 9 hours and 50 minutes 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 Belgrade to Chicago?",
        "answer": "Air Serbia flies nonstop from Belgrade (BEG) to Chicago O'Hare (ORD) six times a week, on Mondays, Wednesdays, Fridays, and Saturdays, with departures spread across the day from mid-morning to late afternoon. The flight covers roughly 4,985 miles and takes about 10 hours 55 minutes westbound, while the return is about an hour shorter at around 9 hours 50 minutes. No other airline offers a nonstop on this route.",
        "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": "Chicago O'Hare (ORD) offers a full range of ground transportation: the CTA Blue Line 'L' train (24-hour service, about 40 minutes to downtown), Metra commuter rail via the O'Hare Transfer Station, Pace suburban buses, taxis, limos, rideshare, rental cars, and airport shuttles. The CTA Blue Line is the most economical option and is widely considered the easiest and most-used public transit choice, with a station directly in the airport terminals. Taxis and rideshare are also popular for door-to-door convenience, while rental cars are plentiful at the Multi-Modal Facility. The fastest option varies by destination and traffic, but the Blue Line offers predictable off-peak travel times around 40 minutes to the Loop.",

        "question": "Which airport should I use in Chicago?",
        "answer": "Chicago has two major airports. O'Hare is the primary international gateway, about 17 miles northwest of downtown, serving as a hub for United and American Airlines and offering extensive global connections. Midway is closer to the city center, roughly 10 miles southwest, and primarily serves domestic flights with Southwest Airlines as the main carrier, making it convenient for regional travel."

        "question": "How do I get to Nikola Tesla Airport from the city center?",
        "answer": "From central Belgrade, the fastest and most popular way to reach Nikola Tesla Airport is by taxi or ride-sharing, which takes about 20 minutes depending on traffic and is moderately priced. Public bus line 72 connects the city center (Zeleni venac) directly to the airport and is the cheapest option, though it can be slower and crowded. A dedicated airport shuttle bus also operates from key points, and driving yourself is possible with on-site parking available, though costs are higher for long stays.",
