        "question": "What is the typical flight duration from Delhi to Kolkata?",
        "answer": "The flight from Delhi to Kolkata is about 810 miles and typically takes 2 hours and 15 minutes nonstop. The return leg is slightly longer at 2 hours and 30 minutes due to prevailing winds. Air India, IndiGo, and SpiceJet all operate daily nonstop service on this route.",
        "methodology": "Flight times and distances come 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). The typical flight time is the median scheduled block time across all carriers on the route, computed the same way in both directions so the difference reflects prevailing winds rather than any change in method. Distance is the great-circle distance between the two airports, so the actual flown track is typically 2-5% longer.",

Three airlines serve the route: IndiGo (6E) runs the most with about 147 weekly departures, Air India (AI) operates around 77 weekly, and SpiceJet (SG) adds roughly 21 weekly flights. All three fly daily, with departures spread from early morning through late evening, and the typical flight time is about 2 hours 15 minutes.",

        "question": "What are the ground transportation options in Kolkata?",
        "answer": "Kolkata's Netaji Subhas Chandra Bose International Airport (CCU) is about 16 km from the city center, and the most-used option is a prepaid taxi or app-based ride share like Uber or Ola, which are readily available outside the terminal. The city's suburban rail network is extensive but the airport's dedicated Biman Bandar station is poorly patronized and slated for replacement by the Yellow Line of the Kolkata Metro, so rail is not a practical airport link today. Public AC and non-AC buses run from the airport to key points, though they can be slow in traffic. Car rentals are available but rarely chosen for city transfers. For most travelers, the fastest and most reliable choice remains a taxi or ride share, especially to central areas like Dalhousie Square.",

        "question": "How do I get to Indira Gandhi Intl Airport from the city center?",
        "answer": "From central Delhi, the Delhi Metro's Airport Express Line is the fastest and most reliable way to reach Indira Gandhi International Airport, connecting New Delhi Railway Station to Terminal 3 in about 20 minutes. Public DTC and cluster buses serve the airport but are slower and subject to road congestion. App-based ride-share services like Uber and Ola, along with prepaid or metered taxis, offer door-to-door convenience at a higher cost than the metro. Driving is possible with both short-term and long-term parking available at the airport, though traffic on the Delhi-Gurgaon Expressway can be heavy during peak hours.",
