        "question": "What is the typical flight duration from Delhi to Hanoi?",
        "answer": "The flight from Delhi to Hanoi covers about 1,860 miles. Nonstop flights typically take around 4 hours 5 minutes, while the return leg from Hanoi to Delhi takes roughly 4 hours 45 minutes due to prevailing winds, making the westbound journey about 40 minutes longer.",
        "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 Hanoi?",
        "answer": "Yes, three airlines fly nonstop from Delhi to Hanoi: IndiGo (6E) has two daily departures, Vietnam Airlines (VN) operates four days a week (Monday, Wednesday, Friday, Sunday), and VietJet Air (VJ) flies on Wednesday, Friday, and Sunday. IndiGo offers the most frequency with 14 weekly flights, while Vietnam Airlines and VietJet together add another 11 weekly flights on overlapping days. The flight takes roughly 4 hours 5 minutes to 4 hours 20 minutes depending on the carrier.",
        "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 Hanoi?",
        "answer": "From Noi Bai International Airport, taxis are a common choice, taking about 30 minutes to the city center and costing roughly 320,000 VND. Public buses 7 and 17 connect the airport to Kim Ma and Long Bien stations for just 5,000 VND, running every 15–20 minutes from 5 a.m. to 10 p.m., though the ride takes about an hour. A shared minibus offers door-to-door service for around 32,000 VND to the Vietnam Airlines office, but it departs only when full. Ride-share apps and car rentals are available but less commonly used than taxis and buses. The most-used option for budget travelers is the public bus, while taxis are favored for speed and convenience.",

        "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 Indira Gandhi Intl Airport from the city center?",
        "answer": "From central Delhi, the fastest way to reach Indira Gandhi International Airport is by taxi or ride‑share (Uber, Ola, or radio taxis), which take about 30–45 minutes depending on traffic and are the most convenient for travelers with luggage. The Delhi Metro's Airport Express Line from New Delhi station is a reliable, lower‑cost option that avoids road congestion and takes roughly 20 minutes to the airport, with feeder buses connecting from other parts of the city. Public DTC and cluster buses are the cheapest choice but can be slow and crowded, while driving yourself is possible with paid parking at the airport, though highway congestion can make it unpredictable.",
