        "question": "What is the typical flight duration from Seoul to Yanji?",
        "answer": "A nonstop flight from Seoul (ICN) to Yanji (YNJ) usually takes about 2 hours 10 minutes to 2 hours 20 minutes. Asiana Airlines and Korean Air often operate this direct route. Flights with a layover, commonly via Beijing or Shanghai, can take 5 to 8 hours or more depending on the connection time. The return flight duration is similar, typically around 2 hours 30 minutes nonstop."
      },
      "q1": {
        "question": "Are there any direct flights from Seoul to Yanji?",
        "answer": "Yes, there are direct non‑stop flights from Seoul Incheon (ICN) to Yanji (YNJ). Six airlines operate the route: Asiana (OZ), Korean Air (KE), Air China (CA), China Eastern (MU), China Southern (CZ), and Jeju Air (7C). All except Jeju Air run daily; Jeju Air flies six days a week (Monday, Wednesday, Thursday, Friday, Saturday, Sunday).",
        "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 Seoul to Yanji?",
        "answer": "Yes, visa requirements apply for travel between Seoul, South Korea, and Yanji, China. South Korean nationals generally need a visa to enter China, though short-term visa-free entry may be available for certain purposes like tourism to select areas, but Yanji is not typically covered. Chinese nationals do not need a visa to return to China. Other nationals should check both South Korean exit/transit requirements and Chinese entry rules based on their passport. Note that China has 24/72/144-hour transit visa-free policies at some ports, but these are not applicable for a direct Seoul-Yanji journey as it is not a transit. Always verify current policies before travel as rules can change."

        "question": "What are the ground transportation options in Yanji?",
        "answer": "Yanji Chaoyangchuan International Airport (YNJ) is located about five kilometers from Yanji city center, making ground transportation straightforward. Taxis are the most commonly used option, offering a quick and inexpensive ride to the center in about ten to fifteen minutes. Ride-share services such as Didi are also available and widely used, often providing a similar experience to taxis. Public buses serve the airport, but they are less frequent and slower, making them a less popular choice. Car rentals are available at the airport but are generally not recommended for city travel due to limited parking and local driving conditions. Most passengers use taxis or ride-share for their convenience, speed, and low cost."
