        "question": "What is the typical flight duration from Hanoi to Delhi?",
        "answer": "The flight from Hanoi to Delhi is about 1,860 miles. The typical nonstop duration is 4 hours and 45 minutes, while the return leg is shorter at 4 hours and 5 minutes, reflecting prevailing winds. Connecting itineraries can take roughly 7 to 12 hours depending on the layover.",
        "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.",

      "q1": {
        "question": "Are there any direct flights from Hanoi to Delhi?",
        "answer": "Yes, three airlines fly nonstop from Hanoi to Delhi. IndiGo (6E) operates two daily flights, while Vietnam Airlines (VN) flies on Mondays, Wednesdays, Fridays, and Sundays, and VietJet Air (VJ) flies on Tuesdays, Thursdays, and Saturdays — together covering every day of the week. The flight takes about 4 hours 45 minutes on average.",
        "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.",

        "question": "What are the ground transportation options in Delhi?",
        "answer": "From Delhi's Indira Gandhi International Airport, the Delhi Metro's Airport Express Line is the fastest and most-used route to the city center, reaching New Delhi Railway Station in about 20 minutes. Prepaid taxis and app-based ride services like Uber and Ola offer door-to-door convenience, while air-conditioned DTC buses provide a budget-friendly alternative. Car rentals are available at the airport, though driving yourself can be challenging due to heavy traffic.",

        "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.",

        "question": "How do I get to Noi Bai Intl Airport from the city center?",
        "answer": "Noi Bai International Airport is about 35 km northeast of downtown Hanoi. The cheapest option is the public bus (routes 86 and 07) which takes 45–60 minutes, while the airport minibus is a slightly faster shared ride. Metered taxis and ride‑share services take around 30 minutes and are the most popular and fastest door‑to‑door choice. Driving yourself is possible via the Nhật Tân Bridge or National Road 3, with both short‑term and long‑term parking at the terminals.",
