Metered taxis are faster at roughly 30 minutes for around 320,000 VND, and airport minibuses offer direct hotel drop-offs from 32,000 VND for foreigners. Ride-share apps and car rentals are also available, but the public bus is the most popular choice for budget travelers.",

        "answer": "There are no nonstop flights from Denver to Hanoi. United Airlines offers the most common one-stop routing, connecting through Tokyo Narita (NRT) with onward legs operated by either ANA or Japan Airlines, though these appear only a few times per day in the schedule. Other connecting routings may exist via different hubs, but United via Tokyo is the primary pattern shown.",
        "methodology": "Airlines and weekly frequencies 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). 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 typical fare is shown for a carrier, it is the median of the real fares Priceline users found on this route in the last 72 hours.",

      "q13": {
        "question": "How do I get to Denver Intl Airport from the city center?",
        "answer": "From downtown Denver, the fastest and most popular option is the RTD A Line train, which runs every 15 minutes and takes about 37 minutes to reach the airport from Union Station, with a one-day pass costing around $10. Ride-share services like Uber and Lyft, as well as taxis, take 25–35 minutes and offer door-to-door convenience at a higher cost. Shared vans and hotel shuttles provide budget-friendly alternatives, and driving yourself means parking at the airport, which is generally the most expensive choice for longer trips.",

United's one-stop option via Tokyo Narita uses a Boeing 787-9 for the long haul to Japan and then a Boeing 767 or Boeing 787-9 on the short leg to Hanoi.

For U.S. routes the type is grounded in the tail number that actually operated the flight; elsewhere it comes from the airline's filed equipment code. Where the source does not commit to a specific variant we name the aircraft family (for example Airbus A320 family) rather than guess, and where no reliable type is on file the aircraft is omitted rather than estimated. Types describe typical scheduled equipment and can vary with seasonal or day-of-week assignments and last-minute swaps.",
