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.", "toolsUsed": [ "flight_schedule" ] }, "q1": { "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.

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.", "toolsUsed": [ "route_airlines", "flight_schedule" ] }, "q3": { "question": "What are the ground transportation options in Chicago?", "answer": "Getting from O'Hare International Airport to downtown Chicago is easiest via the CTA Blue Line 'L' train, which departs directly from the airport every few minutes and takes about 45 minutes to the Loop. Taxis and rideshares like Uber and Lyft are readily available and take roughly 30–60 minutes depending on traffic, with flat-rate taxi fares around $40–50. Rental cars are an option with many on-site companies, though driving and parking in the city can be costly. Shuttle services and regional buses also connect to suburbs and nearby states.

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.

Public bus line 72 runs from Zeleni Venac square to the airport in roughly 40 minutes and is the cheapest option. A dedicated minibus (line A1) also connects Slavija Square with the airport, offering a comfortable middle ground in cost and travel time.
