        "question": "What is the typical flight duration from Kolkata to Delhi?",
        "answer": "A nonstop flight from Kolkata (CCU) to Delhi (DEL) typically takes around 2 hours and 15 minutes. With a layover, total travel time often ranges from 4 to 6 hours depending on the connection city. IndiGo and Air India generally offer the fastest nonstop services, with average block times of approximately 2 hours 10 minutes to 2 hours 20 minutes."
      },
      "q1": {
        "question": "Are there any direct flights from Kolkata to Delhi?",
        "answer": "Yes, there are direct non‑stop flights from Kolkata (CCU) to Delhi (DEL). Air India, IndiGo, and SpiceJet all operate the route daily, with roughly 296 weekly flights combined — Air India alone fields about 121 a week, IndiGo about 154, and SpiceJet around 21.",
        "methodology": "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. 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.",

        "question": "Are overnight (red‑eye) flights available from Kolkata to Delhi?",
        "answer": "Overnight red‑eye flights are available nonstop from Kolkata to Delhi. IndiGo (6E) operates daily red‑eyes departing around 21:15 and 22:30, while Air India (AI) offers daily red‑eyes with departures between 21:00 and 23:00. The flight is short, so these late‑evening departures land the same night, not the next morning.",
        "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.",

IndiGo runs 154 weekly flights, Air India 121, and SpiceJet 21, all with daily service. Typical median fares are not available in the schedule data, but these three carriers provide frequent nonstop options throughout the day.",

      "q9": {
        "question": "How reliable are on‑time departures on this route from Kolkata to Delhi?",
        "answer": "On-time performance is generally acceptable but winter fog in Delhi often causes cascading delays. Early morning flights on IndiGo or Air India tend to have the best punctuality."
      },
      "q10": {
        "question": "Which months have the best weather for traveling to Delhi?",
        "answer": "October to March offers pleasant, cool weather and fewer tourists than the winter peak."
      },
      "q11": {
        "question": "What documents should I bring with me to the airport when flying from Kolkata to Delhi?",
        "answer": "For domestic flights within India, bring a valid government-issued photo ID such as an Aadhaar card, driver's license, or passport. No visa or Real ID is required, but ensure your ID matches the ticket name and carry a payment method for baggage. Vaccination certificates are not currently required."
      },
      "q12": {
        "question": "Which airport should I use in Delhi?",
        "answer": "Delhi has one main airport, Indira Gandhi International (DEL), which serves all commercial flights. It is about 16 km from the city centre, with easy metro and taxi access to attractions like Connaught Place and India Gate."
      },
      "q13": {
        "question": "How do I get to Netaji Subhash Chandra Bose Intl Airport from the city center?",
        "answer": "From central Kolkata, you can reach the airport via the Green Line metro to City Center station, then a short auto or cab ride, which is often the fastest option avoiding traffic. Public buses serve the route on VIP Road, while pre‑paid taxis and app‑based ride‑shares like Ola and Uber offer door‑to‑door convenience at a higher cost. Driving yourself is possible with parking available at the terminal, but traffic can be unpredictable.",
