        "question": "What is the typical flight duration from Belgrade to Chicago?",
        "answer": "The nonstop flight from Belgrade to Chicago is about 4,985 miles and typically takes 10 hours 55 minutes. The return flight from Chicago to Belgrade is shorter, at around 9 hours 50 minutes, due to prevailing winds. Connecting itineraries can range from roughly 13 to 18 hours total travel time, 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.",

Taxis, rideshares, and rental cars are also readily available, along with Metra commuter rail and Pace suburban buses. The Blue Line is the most economical and widely used choice for getting to the city center, while taxis and rideshares offer more direct but pricier alternatives. Rental cars are available for those needing flexibility.",

        "question": "How do I get to Nikola Tesla Airport from the city center?",
        "answer": "The main public transport link between Belgrade city center and Nikola Tesla Airport is city bus line 72, which runs from Zeleni venac directly to the airport terminal, and since January 2025 Belgrade's entire public transport network is free of charge. Taxis and ride-share services are available at the airport and offer a faster, more direct trip, though at a higher cost than the bus. Driving is also possible, with the airport located about 15 km west of the city center and parking available at the terminal. The bus is the most economical option, while taxis or ride-share are the fastest and most popular for travelers with luggage.",
