        "question": "What is the typical flight duration from Tokyo to Hanoi?",
        "answer": "A nonstop flight from Tokyo (NRT) to Hanoi (HAN) typically takes around 5 hours 30 minutes to 6 hours. With one stop, common layover cities include Seoul (ICN) or Hong Kong (HKG), bringing total travel time to roughly 8 to 12 hours depending on the connection. The return flight from Hanoi to Tokyo is often slightly shorter by about 30 minutes due to prevailing winds. Airlines like Vietnam Airlines and Japan Airlines offer competitive nonstop times."

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).

Public buses, including express route 86, are the cheapest choice at about 45,000 VND, reaching the Old Quarter in 45 to 60 minutes, but can be crowded. A new metro line is under construction but not yet operational. Car rentals with a driver are available but less common for solo travelers. Most visitors use Grab or taxis for their balance of comfort and ease."
