        "question": "What is the typical flight duration from Kolkata to Delhi?",
        "answer": "A nonstop flight from Kolkata (CCU) to Delhi (DEL) typically takes about 2 hours 15 minutes to 2 hours 30 minutes. The return flight from Delhi to Kolkata is similar, usually around 2 hours 10 minutes to 2 hours 25 minutes. Direct flights are offered by several airlines, including IndiGo, Air India, and SpiceJet, with flight times varying only slightly. Connecting flights, often via cities like Lucknow or Patna, can take 4 to 8 hours depending on layover duration."
      },
      "q1": {
        "question": "Are there any direct flights from Kolkata to Delhi?",
        "answer": "Yes, there are direct nonstop flights from Kolkata to Delhi, operated daily by IndiGo (6E), Air India (AI), and SpiceJet (SG) with a combined total of 296 weekly flights, so service is very frequent across all days.",
        "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": "Delhi’s Indira Gandhi International Airport (DEL) offers several reliable ways to reach the city center. The Delhi Metro’s Airport Express Line is the quickest option, taking about twenty minutes to New Delhi Railway Station. The regular Magenta Line also connects Terminal 1 to the metro network. Prepaid taxis and app-based ride-share services like Uber and Ola are widely available, taking thirty to sixty minutes depending on traffic and destination. Auto-rickshaws are a cheaper but less comfortable choice for shorter distances, while car rentals with or without drivers are offered at the airport. Most travelers prefer the Airport Express Metro for its speed and value, though taxis and ride-shares are more common for those with luggage or late-night arrivals."
