        "question": "What is the typical flight duration from Da Nang to Haiphong?",
        "answer": "The flight from Da Nang to Haiphong covers about 340 miles and typically takes 1 hour 20 minutes nonstop. The return leg is slightly shorter at 1 hour 15 minutes. Both VietJet Air and Vietnam Airlines operate daily nonstop services on this route.",
        "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 Da Nang to Haiphong?",
        "answer": "Yes, VietJet Air and Vietnam Airlines both fly nonstop from Da Nang to Haiphong daily. VietJet offers three departures a day (morning, mid-morning, and late afternoon), while Vietnam Airlines has two morning departures. The flight takes about 75–80 minutes.",
        "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).

        "question": "What are the ground transportation options in Haiphong?",
        "answer": "Cat Bi International Airport is about 7 km from central Haiphong, and the most common way into the city is a taxi — Mai Linh and Vinasun are the reliable brands, with a trip to the center typically costing 150,000–250,000 VND and taking about 15–20 minutes. A few local buses (routes 02, 03, 16) connect the airport to the city, but they are infrequent, slow, and rarely used by visitors. Ride-hailing apps like Grab and Be operate in Haiphong and are often the best value, with GrabCar fares around 120,000–180,000 VND. There are no car-rental counters, airport rail, or metro links at Cat Bi — renting a car is not practical for most travelers. Taxis and Grab are the most used options, with Grab generally the fastest to secure and cheapest.",

Connecting itineraries with an overnight leg are available via Ho Chi Minh City (SGN): Vietnam Airlines runs a red‑eye from SGN to HPH departing at 21:00 and arriving at 23:00 the same night, after a roughly 1h30m layover in Ho Chi Minh City.",
        "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 Da Nang Intl Airport from the city center?",
        "answer": "From central Da Nang, the most popular and fastest way to reach Da Nang International Airport is by taxi or ride-share (Grab), which take about 10–15 minutes depending on traffic and cost more than public options. Local public buses also serve the airport from the city center, offering a cheaper but slower alternative with limited frequency. Driving yourself is possible with short-term parking at the terminals, though parking fees add to the cost. There is no dedicated airport shuttle bus widely used by travelers, so taxis and Grab are the preferred choices for reliability and speed.",
