        "question": "What is the typical flight duration from Kolkata to Delhi?",
        "answer": "The flight from Kolkata to Delhi is about 820 miles and typically takes 2 hours 30 minutes. The return leg from Delhi to Kolkata is shorter, at about 2 hours 15 minutes, due to prevailing winds. Nonstop service is available on Air India, IndiGo, and SpiceJet.",
        "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.",

        "answer": "At Delhi's Indira Gandhi International Airport (DEL), you have several good ways to reach the city center, about 16 km (10 miles) away. The Delhi Metro's Airport Express Line is the fastest rail option, taking roughly 20 minutes to New Delhi Railway Station, but it runs less frequently than standard metro lines. Taxis and app-based ride services like Uber and Ola are widely available and offer door-to-door convenience, though they can be slower in traffic. Auto-rickshaws are cheaper but often require fare negotiation and are less comfortable for luggage. Public DTC buses are the most used overall form of transport in Delhi, but they are not ideal for airport transfers due to crowding and slower speeds; for most travelers, the Airport Express Line or a pre-booked taxi is the best balance of speed and convenience.",

Driving yourself is possible with paid airport parking, but city traffic can make it unpredictable. A dedicated airport metro link is under construction but not yet operational, so taxis and ride-shares are generally the fastest and most reliable choices.",
