        "question": "What is the typical flight duration from Hanoi to Delhi?",
        "answer": "A nonstop flight from Hanoi (HAN) to Delhi (DEL) typically takes about 4 hours 30 minutes to 5 hours. With one stop, common layovers include Bangkok or Kuala Lumpur, and total travel time usually ranges from 7 to 9 hours. The return flight from Delhi to Hanoi is similar in duration, often around 4 hours 45 minutes nonstop. Airlines like VietJet and IndiGo offer competitive nonstop times."
      },
      "q1": {
        "question": "Are there any direct flights from Hanoi to Delhi?",
        "answer": "Yes, there are direct non‑stop flights from Hanoi (HAN) to Delhi (DEL) on three airlines: IndiGo (6E) operates two flights daily, Vietnam Airlines (VN) flies on Monday, Wednesday, Friday, and Sunday, and VietJet Air (VJ) flies on Tuesday, Thursday, and Saturday, so combined there is at least one non‑stop every day of the week.",
        "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. Carrier service and weekly frequencies are summarized 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). Where available, on-time and cancellation rates come from the U.S. Bureau of Transportation Statistics (BTS) Airline On-Time Performance dataset, and typical fares from the U.S. DOT Airline Origin and Destination Survey (DB1B), a quarterly 10% sample of tickets sold.",

        "question": "Are there visa requirements to travel from Hanoi to Delhi?",
        "answer": "Yes, visa requirements apply for travel from Hanoi to Delhi. Vietnamese citizens must obtain a visa before traveling to India, typically an e-Visa or a regular visa from an Indian mission. Indian citizens traveling to Vietnam can enjoy visa-free entry for stays up to 45 days under the current policy. Nationals of other countries should check both Vietnam's exit requirements and India's entry requirements based on their citizenship."

      "q3": {
        "question": "What are the ground transportation options in Delhi?",
        "answer": "At Delhi's Indira Gandhi International Airport, the Airport Express Line of the Delhi Metro is the most efficient and popular way to reach the city center, taking about twenty minutes to New Delhi Railway Station. It runs frequently and is affordable. Regular taxis and app-based ride-share services like Uber and Ola are available at designated pickup zones, offering door-to-door convenience but taking thirty to sixty minutes depending on traffic. Prepaid taxi booths inside the terminal provide fixed fares and are a safer option than hailing street taxis. Car rentals with or without drivers are available but are less practical for short city stays due to Delhi's heavy congestion. Public buses operated by DTC connect the airport to various parts of the city but are slower and less comfortable. Most travelers use the Airport Express Metro for its speed and reliability."

        "question": "How far in advance should I book tickets from Hanoi to Delhi?",
        "answer": "Specific booking-timing and seasonal data for Hanoi to Delhi aren't available in the system, but live fare snapshots show that booking about 8–10 weeks ahead typically yields the best rates on this route — for example, mid-July nonstop fares around $162–173 versus $214–224 in mid-September and $200–216 in early December. During peak summer and major Indian holiday periods like Diwali (late October/November), fares tend to rise and the ideal window shifts earlier, so aim for 10–12 weeks ahead for those travel dates.",
        "methodology": "Quoted prices come from real-time, bookable flight offers from our airline partners. Prices are dynamic and subject to change throughout the day.",

        "question": "Are overnight (red‑eye) flights available from Hanoi to Delhi?",
        "answer": "There are no nonstop red-eye flights from Hanoi (HAN) to Delhi (DEL). The schedule data shows only connecting overnight options, such as a Thai Airways itinerary via Bangkok where the Bangkok–Delhi leg departs at 11:15 PM and arrives at 2:15 AM, though that involves a long layover in Bangkok.",
        "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.",
