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.", "toolsUsed": [ "flight_schedule" ] }, "q3": { "question": "What are the ground transportation options in Chicago?", "answer": "From Chicago O'Hare, the CTA Blue Line 'L' train is a fast, economical option running directly from the airport to downtown in about 40–45 minutes, and it's the most-used public transit link.
