        "question": "What is the typical flight duration from Delhi to Chennai?",
        "answer": "A direct flight from Delhi (DEL) to Chennai (MAA) typically takes about 2 hours and 45 minutes to 3 hours. The return flight, Chennai to Delhi, usually has a similar duration, averaging around 2 hours and 50 minutes to 3 hours. Indirect flights with common layovers in cities like Mumbai or Hyderabad can increase total travel time to 5–7 hours or more, depending on the layover duration. IndiGo and Air India often offer the fastest direct services."
      },
      "q1": {
        "question": "Are there any direct flights from Delhi to Chennai?",
        "answer": "There are nonstop flights from Delhi (DEL) to Chennai (MAA) operated by IndiGo (6E) and Air India (AI), both running daily with multiple departures throughout the day — IndiGo offers around 19 daily flights and Air India about 10. So you have two airlines serving this route nonstop, every day of the week.",
        "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.",

        "question": "What are the ground transportation options in Chennai?",
        "answer": "Chennai International Airport is about 20 km from the city center. The most used option is prepaid taxis or app-based ride services like Uber and Ola, which offer a reliable and comfortable journey taking 45 to 60 minutes depending on traffic. The Chennai Metro connects the airport via the Blue Line, providing a fast and affordable ride to central areas in about 45 minutes. Local buses run from the airport but are crowded and slower, best for budget travelers. Car rentals are available but less practical due to traffic and parking challenges. For most visitors, ride-hailing apps are the preferred choice for convenience and ease of payment."
