        "question": "What is the typical flight duration from Delhi to Kathmandu?",
        "answer": "The flight from Delhi to Kathmandu covers about 510 miles. Nonstop flights typically take 1 hour and 40 minutes, and the return leg is about the same duration.",
        "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.",

        "question": "Are there any direct flights from Delhi to Kathmandu?",
        "answer": "Yes, there are direct flights from Delhi to Kathmandu. Five airlines operate non‑stop: Air India (9 daily departures), IndiGo (6 daily), Buddha Air (14 weekly, not Tuesdays), Fly91 (11 weekly, not Tuesdays), and Nepal Airlines (1 daily). Air India also runs two overnight red‑eyes at 21:00 and 22:05.",
        "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, flight times and distances for this route come 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). We report the days of the week and the departure times each carrier operates. The typical flight time is the median scheduled block time, given both per carrier and across all carriers on the route; where a schedule does not publish an elapsed time, it is derived from the scheduled departure and arrival times converted to UTC. Outbound and return times are computed by the same method, so the difference between them is directly comparable and reflects prevailing winds rather than any change in derivation. Distance is the great-circle distance between the two specific airports named, so an actual flown track is typically 2-5% longer. Where shown, on-time departure and arrival rates and cancellation rates come from the U.S. Bureau of Transportation Statistics (BTS) Airline On-Time Performance dataset, which covers U.S. domestic routes only; where a typical fare is shown, it comes from the U.S. DOT Airline Origin and Destination Survey (DB1B), a quarterly 10% sample of tickets sold. Aircraft types are taken from the equipment each operating carrier schedules on this route, drawn from published airline timetables and airline equipment schedules in our flight-schedule database. They describe typical scheduled aircraft and can vary with seasonal or day-of-week assignments and last-minute equipment swaps. 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.",

        "question": "What are the ground transportation options in Kathmandu?",
        "answer": "From Tribhuvan International Airport, pre-paid taxis are available in the terminal building and are the most reliable and widely used way to reach central Kathmandu, including Thamel about 6 km away. There is no rail or metro link to the airport, and ride-share apps are not consistently available, so taxis are effectively the primary motorized option. Car rentals are rare for casual visitors, and local mass transit consists of informal buses or tempos that are slow and not recommended with luggage. The fastest practical option is a pre-paid taxi, which takes roughly 20–30 minutes depending on traffic, while hotel shuttles are a comfortable but less common alternative. Overall, the pre-paid taxi stand is the most used and most dependable ground transportation choice for arriving passengers.",

      "q13": {
        "question": "How do I get to Indira Gandhi Intl Airport from the city center?",
        "answer": "Indira Gandhi International Airport sits about 16 km from central Delhi, and the fastest, most convenient option is the dedicated Airport Express Line of the Delhi Metro, which links New Delhi station to the terminals in roughly 20 minutes. Ride-share apps like Uber and Ola, along with prepaid taxis, offer door-to-door service at a higher cost, while public DTC buses are the most economical choice but can be slow in traffic. Driving yourself is possible with on-site parking, though congestion and parking fees make it less popular than the metro for most travelers.",
