        "question": "What is the typical flight duration from Detroit to Ho Chi Minh City?",
        "answer": "Detroit to Ho Chi Minh City is about 8,720 miles. No nonstop flights operate on this route, so a connection is required; total journey time is typically around 21 to 25 hours depending on the layover.",
        "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.",

        "answer": "Tan Son Nhat International Airport (SGN) is about 8 km north of District 1, the city center. The most-used option is a taxi or ride-hailing car (Grab is ubiquitous and reliable), taking 20–40 minutes and costing roughly 100,000–200,000 VND. Public bus routes 109 and 152 serve the airport, are very cheap, but can be slow in traffic. The new Metro Line 1 does not yet connect to the airport, so it is not a direct option. Car rentals are available but rarely used given the chaotic traffic and plentiful alternatives.",
