        "question": "Which U.S. cities can I fly from to reach Korea?",
        "answer": "From the United States, non-stop flights to Korea operate from major West Coast hubs like Los Angeles, San Francisco and Seattle, as well as from Dallas, Atlanta and New York. One-stop itineraries via Tokyo, Shanghai or other Asian hubs are widely available from most large U.S. airports."
      },
      "q1": {
        "question": "Which airports in Korea are the best to fly into?",
        "answer": "From the United States, the primary gateway to Korea is Incheon International Airport near Seoul. Incheon handles the vast majority of long-haul flights and offers excellent connections to domestic destinations like Busan and Jeju via high-speed rail or short flights. Gimhae International Airport in Busan receives some seasonal or charter flights from the US West Coast and serves as a convenient entry point for southern Korea, with good domestic links to Jeju and other cities."
      },
      "q2": {
        "question": "How long is the flight to Korea?",
        "answer": "Non-stop flights from Los Angeles or San Francisco to Seoul Incheon typically take 12 to 13 hours westbound and 10 to 11 hours eastbound. From New York, expect 14 to 15 hours non-stop. One-stop itineraries via Tokyo, Shanghai, or Istanbul add 3 to 8 hours."
      },
      "q3": {
        "question": "Are there direct flights to Korea?",
        "answer": "Non-stop flights from the United States to South Korea are widely available. Major routes include Los Angeles and San Francisco to Seoul Incheon on Korean Air and Asiana Airlines, New York JFK to Seoul on Korean Air and Asiana, and Atlanta, Dallas, and Seattle to Seoul on Korean Air and Delta. Flight times range from 13 to 16 hours westbound and 11 to 14 hours eastbound."
      },
      "q4": {
        "question": "Which U.S. airports are usually cheapest for flying to Korea?",
        "answer": "Los Angeles and San Francisco are typically the cheapest U.S. gateways for flights to Korea, thanks to numerous direct options and high competition. New York can also offer good deals, but travellers from smaller cities often save by booking a separate domestic flight to one of these West Coast hubs."
      },
      "q5": {
        "question": "Which airlines fly to Korea?",
        "answer": "Korean Air, Asiana Airlines, United, Delta, and American fly from the US to Korea, often via Incheon or US hubs with nonstop and one-stop options."
      },
      "q6": {
        "question": "When is the cheapest time to fly to Korea?",
        "answer": "The cheapest months to fly from the US to Korea are August, September, and November, while June, December, and May are the most expensive — so aim for late summer or fall to avoid peak holiday and summer surges. For the best fare, book about 7 to 10 weeks ahead, and whenever possible choose midweek departures and off-peak times like early mornings or late nights to steer clear of the highest demand periods.",
        "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. 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."

      "q7": {
        "question": "How far in advance should I book flights to Korea?",
        "answer": "For flights from the United States to Korea, the optimal booking window is about 7 to 10 weeks before departure, when fares average around $1,170, though you should book earlier — at least 10 to 12 weeks out — for peak summer (June) and winter holiday (December) travel, when prices can climb above $1,300.",

        "question": "Do I need a visa to travel to Korea?",
        "answer": "For United States nationals, a visa is not required for a short tourist visit to South Korea. Travelers can stay for up to 90 days, but must obtain a Korea Electronic Travel Authorization before departure.\n\nThis is general guidance to help you plan, not official immigration advice — entry rules can change and can depend on your nationality and circumstances, so please confirm the current requirements with the relevant embassy or official government source before you travel.",

        "question": "How easy is it to travel within Korea after I arrive?",
        "answer": "South Korea has an efficient high-speed KTX rail network connecting major cities like Seoul, Busan, and Daegu, along with express buses and domestic flights to Jeju Island. Arriving at Incheon (Seoul) gives you the most seamless onward connections by train or bus, while landing in Busan or Jeju may require a flight or train transfer to reach other regions."
