        "answer": "A nonstop flight from Haiphong (HPH) to Da Nang (DAD) typically takes around 1 hour 20 minutes.

Both carriers fly the route daily, with VietJet offering three daily departures (around 07:55, 11:20, and 19:10) and Vietnam Airlines offering two daily departures (around 11:15 and 11:25).",
        "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 Da Nang?",
        "answer": "Da Nang International Airport is located just three kilometers from the city center, making ground transportation quick and easy. Taxis are readily available outside the terminal and are the most used option, offering a short five to ten minute ride to central areas. Ride-share services like Grab are also widely used, often at a lower cost and with the convenience of app-based booking. Public buses serve the route but are infrequent and less practical for visitors with luggage. There is no dedicated mass transit link from the airport. Car rentals are available but are generally unnecessary for city-center access given the short distance. Most travelers opt for taxis or Grab for their speed and convenience."
