        "question": "Are there any direct flights from Chicago to Kolkata?",
        "answer": "There are no nonstop flights from Chicago to Kolkata. The shortest one-stop connections are via Abu Dhabi (Etihad, about 18.5 hours total), Doha (Qatar Airways, about 18 hours), or Dubai (Emirates, about 20 hours), with Etihad and Qatar offering the most frequent options. These itineraries use Boeing 787-9 or Airbus A350-1000 aircraft on the long leg.",
        "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. Aircraft types are taken from the equipment each operating carrier schedules on this route, drawn from published airline timetables and airline equipment schedules in our flight-schedule database. They describe typical scheduled aircraft and can vary with seasonal or day-of-week assignments and last-minute equipment swaps.",

        "question": "What are the ground transportation options in Kolkata?",
        "answer": "From Kolkata Airport (CCU) to the city center, prepaid taxis and app-based ride services like Uber and Ola are the most reliable and popular choices, with a typical journey of about 16 km taking 45–75 minutes depending on traffic. An air-conditioned Volvo bus (route AC-39) connects the airport to key points like Howrah and the city center, but it can be crowded and slower. There is no direct metro line from the airport yet; the nearest station is about 10 km away, requiring a connecting auto-rickshaw or bus. Car rentals are available at the terminal but are less common for city transfers. Most travelers use prepaid or app-based taxis for their convenience and fixed pricing.",

        "answer": "DuPage Airport (DPA) is a general aviation airport in West Chicago, about 29 miles west of downtown, with no scheduled commercial service to Kolkata. There is no direct public transit; the nearest Metra station is West Chicago on the Union Pacific West line, from which a taxi or ride‑share is needed. Driving via I‑290 and I‑88 takes roughly 45 minutes to an hour in normal traffic, and parking is readily available on‑site. Ride‑share and taxis are the most practical door‑to‑door options, with ride‑share typically being the most popular and cost‑effective for the distance.",
