        "question": "Which cities in Korea can I fly to from Washington?",
        "answer": "From Washington you can reach Seoul Incheon non-stop, which is the main gateway. Other cities like Busan or Jeju require a connection, usually in Seoul or sometimes in Tokyo. Seoul is best for history and culture, while Busan and Jeju are popular for beaches and coastal scenery."
      },
      "q1": {
        "question": "How long is the flight from Washington to Korea?",
        "answer": "From Washington to Seoul, non-stop flights typically take 14 to 15 hours westbound and about 13½ hours eastbound on the return. One-stop routes to Seoul or Busan commonly range from 17 to 22 hours total travel time depending on layover length."
      },
      "q2": {
        "question": "Are there direct flights from Washington to Korea?",
        "answer": "Yes, there are non-stop flights from Washington Dulles to Seoul Incheon on Korean Air. Flight time is about 14 to 15 hours westbound and slightly shorter eastbound. If you fly from Reagan National or Baltimore, you'll need a connection, often via a U.S. hub or Tokyo, with total travel times of 17 hours or more."
      },
      "q3": {
        "question": "Which airlines fly from Washington to Korea?",
        "answer": "Korean Air flies nonstop from Washington Dulles to Seoul. One-stop options include Delta, United, American, and their Asian partners via hubs."
      },
      "q4": {
        "question": "When is the cheapest time to fly from Washington to Korea?",
        "answer": "The cheapest months to fly from Washington to Korea are September, October, and November, with early fall offering the lowest fares of the year, while peak summer (June–July) and December holidays are the most expensive. Booking about 7 to 10 weeks ahead typically yields the best price, and midweek departures tend to be cheaper than weekends, though exact day-of-week patterns aren't available for this route. Late spring and early fall also see lower demand, so flying outside of summer and major holiday periods will generally save you money.",
        "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."

        "question": "How far in advance should I book flights from Washington to Korea?",
        "answer": "For flights from Washington to Korea, the optimal booking window is about 7 to 10 weeks ahead of departure, when average fares drop to around $1,539.",

        "question": "What are the most popular cities to visit in Korea?",
        "answer": "In South Korea, Seoul is the main gateway with palaces, markets and nightlife. Busan offers beaches and seafood, while Gyeongju is known for ancient tombs and temples. Jeju Island provides volcanic landscapes and coastal walks, reachable by a short flight from Seoul."
      },
      "q7": {
        "question": "Do I need a visa to travel from Washington to Korea?",
        "answer": "For a United States citizen travelling from Washington to South Korea, no visa is required for a short tourist visit, and the permitted stay is up to 90 days. However, a Korea Electronic Travel Authorization must be obtained before travel, even though entry is visa-free.\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.",

        "answer": "From Washington to Korea, Incheon International Airport near Seoul is the primary gateway with the most long-haul flights and excellent high-speed train connections across the country. If you are heading to Busan or the south coast, Gimhae International Airport can be more convenient but has fewer direct U.S. flights."

        "question": "When is the best time of year to visit Korea?",
        "answer": "For Korea, April to June and September to October offer mild weather and lighter crowds than the hot, rainy summer, with spring cherry blossoms and autumn foliage enhancing Seoul and other destinations."

      "q13": {
        "question": "How do I get to Ronald Reagan National Airport from the city center?",
        "answer": "From downtown Washington, D.C., the most direct way to Ronald Reagan Washington National Airport is the Metrorail Blue or Yellow line, whose elevated station is directly connected to the concourse level of Terminals B and C, with a free shuttle bus or walkway to Terminal 1. Ride-app services like Uber and Lyft pick up on designated outer curbs at each terminal, while taxis and pre-arranged sedan or limo services are also available. Driving yourself is straightforward with on-airport garages and an economy lot connected by free 24/7 shuttles, and Metrobus route 5A provides a slower local bus option to downtown. Metrorail is generally the fastest and most popular choice for avoiding traffic, while ride-share and taxis are more convenient but pricier, and parking is the most flexible but often the most costly for longer trips.",
