        "question": "What is the typical flight duration from Hanoi to Chiang Mai?",
        "answer": "A direct flight from Hanoi (HAN) to Chiang Mai (CNX) typically takes about 1 hour and 40 minutes. There are no significant differences in flight duration between eastbound and westbound on this route. Most flights are nonstop, but if a layover is required, the most common connection is via Bangkok (BKK), which extends total travel time to around 4 to 6 hours depending on the layover duration. Airlines like VietJet Air and Thai AirAsia offer competitive flight times on this route."

        "question": "Are there any direct flights from Hanoi to Chiang Mai?",

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. 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).

        "question": "What are the ground transportation options in Chiang Mai?",
        "answer": "Chiang Mai International Airport is located very close to the city center, about three to four kilometers southwest of the Old City. Taxis are readily available at the airport; you can book a metered taxi at the official counter inside the terminal, with a typical fare of around 150 to 200 Thai Baht and a travel time of roughly ten to fifteen minutes. Ride-share services like Grab are also widely used and often slightly cheaper than airport taxis, but you may need to meet your driver at a designated pickup point. The red songthaews, shared pickup trucks with benches, are a popular and inexpensive local option, costing about 40 Baht per person, though they may take longer as they pick up other passengers. There is no train or subway connecting the airport to the city. Car rentals are available but generally unnecessary for getting to the city center given the short distance. Most visitors use either Grab or the red songthaews, with Grab being the most convenient and commonly chosen for first-time arrivals."
