Nearly all carriers fly daily; the exception is Thai VietJet Air (WE), which runs four times a week on Wednesdays, Thursdays, Saturdays, and Sundays.",
        "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. 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). Where available, on-time and cancellation rates come from the U.S. Bureau of Transportation Statistics (BTS) Airline On-Time Performance dataset, and typical fares from the U.S. DOT Airline Origin and Destination Survey (DB1B), a quarterly 10% sample of tickets sold.",

        "question": "Are there visa requirements to travel from Nha Trang to Seoul?",
        "answer": "Yes, there are visa requirements for travel from Nha Trang, Vietnam to Seoul, South Korea.

If you are a South Korean national, you can enter Vietnam visa-free for up to 45 days for tourism. Travelers of other nationalities should check both Vietnam exit requirements and South Korean entry rules based on their passport."

Car rentals are available but not recommended for city travel due to heavy traffic and limited parking. Most travelers prefer the AREX Express for its speed and reliability, though buses are popular for those with heavy luggage or hotels near bus stops."
