        "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": "Ground transportation from Netaji Subhas Chandra Bose International Airport (CCU) to central Kolkata is available by pre-paid taxi, app-based ride shares like Uber and Ola, and public buses, with car rentals also an option. The airport is about 16 km from Dalhousie Square, and the fastest door-to-door choice is typically a taxi or ride share given Kolkata's traffic. A dedicated airport metro line is under development, but currently the most-used and practical option for most travelers is a pre-paid taxi or ride share. Public buses are cheaper but slower and less comfortable with luggage. Kolkata's broader transport network includes an extensive suburban rail and metro system once you reach the city center.",

A small number of itineraries combine an Etihad long‑haul with a short Air Arabia Abu Dhabi connection, also via Abu Dhabi. Typical per‑carrier fares are not available for this route.",

        "question": "How do I get to Dupage County from the city center?",
        "answer": "DuPage Airport is a general aviation reliever airport with no scheduled commercial passenger service, so there are no public transit, shuttle, or ride-share options designed for airline passengers. Private car or taxi is the only practical way to reach it from downtown Chicago, typically a 35–45 minute drive via I-290 and I-88. Driving and parking is straightforward with ample on-site parking, but costs are higher than using a public bus or train since none exist for this trip.",

Netaji Subhas Chandra Bose International Airport in Kolkata provides standard assistance for passengers with reduced mobility and can be contacted through the Airports Authority of India or your airline for advance arrangements, though dedicated children's play areas are not detailed in public schedules. For either airport, requesting wheelchair or mobility support at least 48 hours in advance is the reliable way to secure service.",
