        "question": "What is the typical flight duration from Seoul to Yanji?",
        "answer": "The flight from Seoul to Yanji covers about 410 miles. Nonstop flights typically take 2 hours 25 minutes, with the return leg lasting about 2 hours 30 minutes — a small difference that doesn't meaningfully favor either direction.",
        "methodology": "Flight times and distances 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). The typical flight time is the median scheduled block time across all carriers on the route, computed the same way in both directions so the difference reflects prevailing winds rather than any change in method. Distance is the great-circle distance between the two airports, so the actual flown track is typically 2-5% longer.",

        "answer": "No overnight red‑eye flights operate from Seoul (ICN) to Yanji (YNJ) — there are no nonstop red‑eyes on this route and no connecting itineraries whose long leg is a red‑eye.",
        "methodology": "Red-eye flights are identified from scheduled local departure and arrival times in our flight-schedule database — built from published airline timetables and official schedule data, including U.S. Department of Transportation records for domestic routes — flagging services that depart late at night and arrive the following morning; for connecting itineraries the red-eye is based on the timing of the overnight long-haul leg.",

        "question": "Which airlines usually operate this route from Seoul to Yanji?",
        "answer": "Six airlines fly nonstop from Seoul Incheon to Yanji: Asiana Airlines (15 weekly flights), Korean Air (14 weekly flights), Air China, China Eastern, and China Southern (each daily), plus Jeju Air (6 weekly). Fares for this route aren't listed in the schedule data, so typical prices aren't available. All flights operate daily except Jeju Air, which runs six days a week.",
        "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.",

      },
      "q10": {

      },
      "q11": {
        "question": "What documents should I bring with me to the airport when flying from Seoul to Yanji?",
        "answer": "Bring a passport valid for at least six months, a Chinese visa unless eligible for visa-free transit, proof of onward or return travel, a payment method for baggage, and any required vaccination certificates."
      },
      "q12": {
        "question": "Which airport should I use in Yanji?",

      "q13": {
        "question": "How do I get to Incheon Intl Airport from the city center?",
        "answer": "To reach Incheon International Airport from central Seoul, the Airport Railroad Express (AREX) offers both an all-stop commuter train and a non-stop express service to Seoul Station, taking about 43–60 minutes and being the fastest option. Airport limousine buses serve numerous city-center stops with direct, comfortable rides but are subject to traffic. Taxis and ride‑share services provide door‑to‑door convenience at a significantly higher cost, while driving yourself is possible with both short‑term and long‑term parking available at the airport.",

Connecting itineraries, which route through Chinese hubs like Jinan, Qingdao, and Beijing, predominantly use Boeing 737-800s on both legs, with occasional Airbus A330 or A321 variants on the longer segment. The exact aircraft can vary by day and airline, but the 737-800 and A320neo family are the workhorses here. Wi-Fi and seatback entertainment are widely available on these aircraft, though the actual offering depends on the carrier and specific aircraft.",
