        "question": "What is the typical flight duration from Tokyo to Da Nang?",
        "answer": "A direct flight from Tokyo (NRT) to Da Nang (DAD) typically takes about 5 hours 30 minutes to 6 hours. With one stop, common layover cities include Ho Chi Minh City or Hanoi, making the total travel time around 8 to 12 hours. The return flight from Da Nang to Tokyo is often slightly shorter, around 5 hours 15 minutes to 5 hours 45 minutes nonstop."

      "q1": {
        "question": "Are there any direct flights from Tokyo to Da Nang?",
        "answer": "Yes, Vietnam Airlines (VN) flies nonstop from Tokyo Narita (NRT) to Da Nang (DAD) with 11 weekly flights operating daily, offering multiple departures around 9:00 AM to 10:30 AM.",
        "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 Tokyo to Da Nang?",
        "answer": "Yes, visa requirements apply when traveling from Tokyo to Da Nang, and they depend on your nationality. Japanese citizens can enter Vietnam visa‑free for stays up to 45 days. Vietnamese citizens do not need a visa to return home. Travelers of other nationalities should check Vietnam's visa policy: many can obtain an e‑visa online for stays up to 90 days, while some may need a visa in advance. Always verify current rules before travel."

      "q3": {
        "question": "What are the ground transportation options in Da Nang?",
        "answer": "Da Nang International Airport is located only about three kilometers from the city center, making ground transportation quick and straightforward. Taxis are readily available outside the terminal and are the most popular option, offering a short, metered ride to central areas in around ten minutes. Ride-share services like Grab are widely used and often cheaper than taxis, providing a convenient alternative via a smartphone app. There is no train or metro directly at the airport, but public buses serve routes along major roads near the terminal, though they are less frequent and less convenient for visitors with luggage. Car rentals are available but rarely necessary for city travel, as parking can be challenging and the city is compact. Most travelers use taxis or Grab for their ease and low cost."

      "q6": {
        "question": "Are overnight (red‑eye) flights available from Tokyo to Da Nang?",
        "answer": "There are no nonstop red-eye flights from Tokyo (NRT) to Da Nang (DAD). Connecting options exist where the long leg is an overnight flight, such as via Hong Kong on HK Express departing at 9:35 PM and arriving at 1:30 AM, but these involve a long layover and are not direct overnight services on the Tokyo–Da Nang segment itself.",
        "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.",
