        "question": "What is the typical flight duration from Chicago to Chennai?",
        "answer": "There is no scheduled nonstop service from Chicago to Chennai, so the journey requires a connection. The distance between the cities is about 8,570 miles, and a typical one-stop itinerary takes approximately 20 to 24 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.",

      "q1": {
        "question": "Are there any direct flights from Chicago to Chennai?",
        "answer": "There are no nonstop flights from Chicago to Chennai. The shortest one-stop routings typically connect through Abu Dhabi (on Etihad, about 19–20 hours total travel time), London Heathrow (on British Airways, roughly 21 hours), or Frankfurt (on Lufthansa/United, around 20.5 hours). These itineraries involve a single layover and cover the approximately 8,575-mile great-circle distance.",

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.",

Travelers must obtain an eVisa, which permits a stay of 30 days.\n\nThis is general guidance to help you plan, not official immigration advice — entry rules can change and can depend on your nationality and circumstances, so please confirm the current requirements with the relevant embassy or official government source before you travel.",

        "answer": "Chennai International Airport (MAA) is about 21 km (13 mi) southwest of the city center and is directly served by the Chennai Metro via the Chennai International Airport Metro Station, as well as the Tirusulam station on the Chennai Suburban Railway. The metro is the fastest, most reliable way to reach the city center, while the suburban rail is a cheaper but slower alternative. Prepaid taxis and app-based ride shares like Ola and Uber are widely available outside the terminals and are the most commonly used option for door-to-door convenience. Car rentals are also available, but driving in Chennai traffic is generally not recommended for visitors. Overall, most travelers use ride shares or taxis for comfort, while budget-conscious passengers opt for the metro.",

      "q13": {
        "question": "How do I get to Dupage County from the city center?",
        "answer": "DuPage Airport is a general aviation airport with no scheduled commercial passenger service, so there are no public transit, shuttle, or ride-share options designed for airline passengers from downtown Chicago. Reaching it from the city center would require driving roughly 30 miles west via I-290 and I-88, with parking available at the airport's fixed-base operator. Taxis or ride-shares can be hired for the trip, but this is uncommon and relatively expensive compared to using O'Hare or Midway. For your flight to Chennai, O'Hare International Airport is the realistic departure point from Chicago, with the CTA Blue Line offering the fastest and most popular public transit option from downtown.",
