        "question": "What is the typical flight duration from Hong Kong to Hanoi?",
        "answer": "A nonstop flight from Hong Kong (HKG) to Hanoi (HAN) typically takes about 2 hours 5 minutes. Connecting flights with one stop, often via Ho Chi Minh City or Bangkok, can extend total travel time to 5–8 hours."
      },
      "q1": {
        "question": "Are there any direct flights from Hong Kong to Hanoi?",
        "answer": "Yes, nonstop flights from Hong Kong (HKG) to Hanoi (HAN) are available daily on Cathay Pacific, HK Express, Vietnam Airlines, and Hong Kong Airlines. Cathay Pacific offers up to 26 weekly flights, HK Express runs 14 weekly, and both Vietnam Airlines and Hong Kong Airlines operate 7 weekly, all with daily service.",
        "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. Where a median fare is shown for a carrier, it reflects the real fares Priceline users found on this route in the last 72 hours.",

Travelers of other nationalities should check Vietnam's visa policy, as many can obtain an e-visa or visa on arrival, and Hong Kong's entry requirements based on their passport."

        "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.",
