        "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": "Delhi's Indira Gandhi International Airport is about 15 km from New Delhi Railway Station and 16 km from the city center, with several ground transport options. The Delhi Metro is the fastest and most reliable way into the city, while buses remain the most-used mode overall, carrying about 60% of Delhi's commuting demand. Taxis are widely available, with over 148,000 registered vehicles, and app-based services like Uber and Ola are popular. Auto-rickshaws are cheaper than taxis but often require haggling, and cycle-rickshaws work well for short trips. Car rentals are possible but generally less practical than these public options given Delhi's 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.",

        "answer": "Common layovers include Bangkok, Kuala Lumpur, Singapore, and Ho Chi Minh City. Bangkok offers visa‑free transit for many nationalities and frequent connections. Kuala Lumpur and Singapore provide efficient, modern airports with broad onward networks. Ho Chi Minh City is a logical geographic midpoint, often resulting in competitive total travel times."

      },
      "q13": {
        "question": "How do I get to Noi Bai Intl Airport from the city center?",
        "answer": "From central Hanoi, the most popular and fastest way to reach Noi Bai International Airport is by metered taxi or ride-share, which takes about 30 minutes and costs around 320,000 VND. For a much cheaper option, public buses 7 and 17 run every 15–20 minutes from the city center to the airport in about an hour, while airport minibuses offer direct hotel drop-off for a modest fare. Driving yourself is possible, but parking at the airport adds cost and hassle compared to the other choices.",

Encalm Sleep Pods are also available airside in Terminal 3, providing a private, enclosed space to lie down for a few hours. Additionally, the Holiday Inn Express New Delhi International Airport is connected to Terminal 3 on Level 5, though it is landside, meaning travellers must clear immigration and customs to access it.",

For U.S. routes the type is grounded in the tail number that actually operated the flight; elsewhere it comes from the airline's filed equipment code. Where the source does not commit to a specific variant we name the aircraft family (for example Airbus A320 family) rather than guess, and where no reliable type is on file the aircraft is omitted rather than estimated. Types describe typical scheduled equipment and can vary with seasonal or day-of-week assignments and last-minute swaps.",
