        "question": "What is the typical flight duration from Delhi to Kolkata?",
        "answer": "A nonstop flight from Delhi (DEL) to Kolkata (CCU) typically takes about 2 hours 5 minutes to 2 hours 15 minutes. Flights with a layover, most commonly via Patna or Varanasi, usually extend total travel time to 4–7 hours depending on the connection duration."
      },
      "q1": {
        "question": "Are there any direct flights from Delhi to Kolkata?",
        "answer": "Yes, there are direct non-stop flights from Delhi to Kolkata, operated daily by IndiGo (6E), Air India (AI), and SpiceJet (SG). IndiGo runs the most frequencies with about 21 departures each day, Air India offers around 11 daily, and SpiceJet has 3, giving a combined total of roughly 245 weekly non-stop flights. All three carriers fly the route 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. 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 and weekly frequencies are summarized 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). Where available, on-time and cancellation rates come from the U.S. Bureau of Transportation Statistics (BTS) Airline On-Time Performance dataset, and typical fares from the U.S. DOT Airline Origin and Destination Survey (DB1B), a quarterly 10% sample of tickets sold.",

        "question": "Are overnight (red‑eye) flights available from Delhi to Kolkata?",

        "methodology": "Red-eye flights are identified from scheduled local departure and arrival times in our flight-schedule database — built from published airline timetables and official schedule data, including U.S. Department of Transportation records for domestic routes — flagging services that depart late at night and arrive the following morning; for connecting itineraries the red-eye is based on the timing of the overnight long-haul leg.",
