        "question": "What is the typical flight duration from Chennai to Delhi?",
        "answer": "A nonstop flight from Chennai (MAA) to Delhi (DEL) typically takes about 2 hours 45 minutes to 3 hours. IndiGo and Air India often operate the fastest nonstop services. The return flight from Delhi to Chennai is similar, usually around 2 hours 50 minutes to 3 hours 5 minutes due to wind patterns. Flights with layovers, most commonly via Mumbai or Hyderabad, can take 5 to 8 hours or more depending on the connection time."

      "q1": {
        "question": "Are there any direct flights from Chennai to Delhi?",
        "answer": "There are plenty of nonstop flights from Chennai (MAA) to Delhi (DEL), operated daily by both IndiGo (6E) and Air India (AI). IndiGo runs about 20 flights a day and Air India around 12, with departures spread from early morning through late evening, so you have frequent options 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 Delhi?",
        "answer": "Indira Gandhi International Airport (DEL) offers several ground transportation options to Delhi's city center. The Delhi Metro's Airport Express Line is fast, reliable, and avoids traffic, reaching New Delhi Railway Station in about twenty minutes; it is the most used option. Regular metro lines and feeder buses also serve the airport but take longer. Prepaid taxis and app-based ride shares like Uber and Ola are widely available and convenient, especially with luggage, taking thirty to sixty minutes depending on traffic. Car rentals are available but less practical for city use. Buses operated by DTC connect to various parts of the city but are slower and less comfortable. Most travelers prefer the Airport Express Line for its speed and cost-effectiveness."
