        "question": "Are there any direct flights from Houston to Hanoi?",
        "answer": "There are no non‑stop flights from Houston (HOU) to Hanoi (HAN). The shortest one‑stop connections route through Taipei (EVA Air) or Tokyo Narita (United/ANA), with the long leg lasting about 15½ hours and total travel time running roughly 20–22 hours depending on the layover. EVA Air via Taipei offers the shortest combined flight time of the options seen.",
        "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. Carrier service, flight times and distances for this route come 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). We report the days of the week and the departure times each carrier operates. The typical flight time is the median scheduled block time, given both per carrier and across all carriers on the route; where a schedule does not publish an elapsed time, it is derived from the scheduled departure and arrival times converted to UTC. Outbound and return times are computed by the same method, so the difference between them is directly comparable and reflects prevailing winds rather than any change in derivation. Distance is the great-circle distance between the two specific airports named, so an actual flown track is typically 2-5% longer. Where shown, on-time departure and arrival rates and cancellation rates come from the U.S. Bureau of Transportation Statistics (BTS) Airline On-Time Performance dataset, which covers U.S. domestic routes only; where a typical fare is shown, it comes 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 Hanoi?",
        "answer": "From Noi Bai International Airport (HAN), the most practical options into central Hanoi, about 35 km away, are metered taxis and public buses. Taxis are readily available at both terminals, take roughly 30 minutes, and cost around 320,000 VND; they are the fastest and most-used choice. Public buses and minibuses also serve the airport as a budget alternative. Ride-share services like Grab operate in Hanoi and can be booked via app, while car rentals are available but less common for the drive into the city.",

Tokyo and Seoul offer efficient connections with broad Asian networks, Taipei provides smooth transfers and visa‑free transit for many nationalities, and Doha gives a one‑stop routing with competitive total times."

        "answer": "William P. Hobby Airport (HOU) is about 7–11 miles from downtown Houston. Ride‑share services like Uber and Lyft are the most popular and usually the fastest option; taxis are also available curbside. Public transit is limited to a few bus routes (not a direct rail link), and shared shuttle vans serve many hotels. Driving and parking are straightforward with several on‑airport lots, but costs are higher than off‑airport options.",
