        "question": "What is the typical flight duration from New York to Seoul?",
        "answer": "A nonstop flight from New York (JFK) to Seoul (ICN) typically takes about 14 to 15 hours. The return flight from Seoul to New York is often slightly longer, around 14 to 15.5 hours, due to prevailing winds. With one stop, common layover cities include Tokyo, Beijing, or Dubai, bringing total travel time to roughly 17 to 20 hours. Korean Air and Asiana Airlines offer nonstop service with similar flight times, while airlines like Emirates or Japan Airlines provide one-stop options."
      },
      "q1": {
        "question": "Are there any direct flights from New York to Seoul?",
        "answer": "Yes, there are non‑stop flights from New York to Seoul. Four airlines — Korean Air (KE) and Asiana Airlines (OZ) from JFK, plus Air Premia (YP) and United (UA) from Newark — operate daily non‑stops to Incheon, with multiple departures spread across the day.",
        "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 New York to Seoul?",
        "answer": "Yes, there are visa requirements for travel from New York to Seoul, depending on your nationality. U.S. citizens can enter South Korea visa-free for tourism or business for up to 90 days under the K-ETA (Korea Electronic Travel Authorization) system, which must be obtained before travel. Non-U.S. citizens should check South Korea's visa policy based on their nationality. For the return from Seoul to New York, U.S. citizens do not need a visa, but foreign nationals may require a U.S. visa or ESTA if eligible under the Visa Waiver Program."

      "q3": {
        "question": "What are the ground transportation options in Seoul?",
        "answer": "Seoul is served by two major airports: Incheon International (ICN) and Gimpo International (GMP). From Incheon, the AREX Express train reaches Seoul Station in about forty-three minutes non-stop, while the All-Stop train takes around sixty minutes. Airport limousine buses serve many city districts but are subject to traffic. Taxis and ride-share services are available, with a journey time of sixty to ninety minutes depending on traffic. Car rentals are possible but not recommended for city travel due to congestion and parking issues. Most travelers use the AREX Express for its speed and reliability. From Gimpo, the AREX All-Stop train connects to central Seoul in about twenty minutes, and it is the most popular choice due to its convenience and low cost."

      "q4": {
        "question": "When is the cheapest time to fly from New York to Seoul?",
        "answer": "Based on seasonal price data, the cheapest months to fly from New York to Seoul are September (averaging $994), October ($1004), and November ($1010), while the most expensive months are June ($1398), December ($1382), and July ($1285).",
        "methodology": "This 'good deal' estimate shows a representative best price for each departure date across roughly a 12-month window (about 3 months back and 9 months forward). It is built from real flight prices found by Priceline users searching this route, accumulated into a price history for each departure date. Rather than weighting all of that history equally, we apply exponential time decay so recent prices dominate — a price seen yesterday counts almost in full, one from about a month ago roughly a third, and prices from a few months back very little — giving a figure that tracks today's market instead of a stale long-run average. Clear price outliers are removed before any calculation, departure dates with no observations are filled in from nearby dates, and the resulting curve is lightly smoothed so it reads as a clean seasonal trend rather than day-to-day noise.",

      "q5": {
        "question": "How far in advance should I book tickets from New York to Seoul?",
        "answer": "For the best fares from New York to Seoul, aim to book roughly 23 to 26 weeks (about 5.5 to 6 months) before departure, when average prices drop to around $1,405. Booking very early—around 180 days out—can yield the lowest single price near $1,391, while waiting until the last minute drives costs up to about $1,567. During peak summer or holiday periods, it's wise to add several weeks to that window, as demand pushes optimal booking closer to 6–7 months ahead.",
        "methodology": "This booking-window guidance is built from the same real flight prices found by Priceline users searching this route, re-grouped by how many days before departure each price was seen (from the departure day out to about 180 days ahead) across the route's price history. At each booking lead time we report the 25th-percentile price — the cheaper end of what travelers were quoted, rather than the rock-bottom minimum (which can be a fluke) or the average (which is pulled up by expensive last-minute fares). The buy-or-wait advice then applies a risk premium that grows as departure approaches, since seat availability shrinks and prices become less predictable; using that adjusted curve we flag windows where waiting is likely to save a meaningful amount (at least $20 or 5%) versus windows where booking now is the better call. Isolated single-day recommendations are filtered out, so the advice only reflects a window that holds for several days in a row.",

        "answer": "No overnight (red‑eye) flights are available from New York to Seoul — there are no nonstop red‑eyes on this route, and no connecting itineraries with a red‑eye long leg were found in the schedule data.",
        "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.",

Typical median fares are around $1,634 on Korean Air, $1,997 on Asiana, $1,215 on Air Premia, and $1,900 on United.",

        "question": "If I need a connection, what are common layover cities between New York and Seoul?",
        "answer": "Common layover cities include Incheon (already Seoul’s main airport, but for connections beyond), Tokyo (Narita or Haneda), Shanghai (Pudong), and Hong Kong. Tokyo offers efficient transfers and a single connection on Japanese or Korean carriers. Shanghai provides competitive total travel times on Chinese airlines, though a visa or transit visa may be required depending on nationality. Hong Kong is a major hub with broad connections and visa-free transit for many passport holders. Note that Incheon itself is the primary gateway to Seoul, so most flights arrive directly; connections via these cities are typically for travelers departing from New York airports other than JFK or Newark, or when direct flights are unavailable."

        "question": "How reliable are on‑time departures on this route from New York to Seoul?",
