        "question": "What is the typical flight duration from Da Nang to Haiphong?",
        "answer": "A direct flight from Da Nang to Haiphong typically takes around 1 hour and 15 minutes.

      "q1": {
        "question": "Are there any direct flights from Da Nang to Haiphong?",
        "answer": "Yes, two airlines fly nonstop from Da Nang (DAD) to Haiphong (HPH): VietJet Air (VJ) and Vietnam Airlines (VN), both operating daily. VietJet runs three flights a day (around 06:00, 09:30, and 17:20) while Vietnam Airlines offers two daily departures around 09:25–09:35.",
        "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": "What are the ground transportation options in Haiphong?",
        "answer": "Cat Bi International Airport (HPH) is located only about seven kilometers from downtown Haiphong, making ground transportation quick and easy. Official airport taxis and ride-hailing services like Grab are the most convenient and widely used options, with a trip to the center taking roughly fifteen minutes and costing a few dollars. Public buses, including route 16, serve the airport but are infrequent and less comfortable, so they are rarely used by visitors. Car rentals are not common for city-center travel, and there is no rail connection. Taxis and ride-share are the best balance of cost and convenience, with Grab being the most popular choice."

        "question": "Are overnight (red‑eye) flights available from Da Nang to Haiphong?",
        "answer": "There are no nonstop red-eye flights from Da Nang to Haiphong. A connecting overnight option exists via Ho Chi Minh City (SGN) on VietJet Air, where the SGN–HPH leg departs around 9:20 PM and arrives at 11:20 PM, but that is a late-evening domestic hop rather than a true overnight flight arriving the next morning.",
        "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.",
