        "question": "Which cities in Korea can I fly to from Seattle?",
        "answer": "From Seattle you can fly non-stop to Seoul Incheon. One-stop connections via Seoul or other Asian hubs can take you to Busan, Jeju, or Daegu. Most travelers fly into Seoul and then take domestic flights or the high-speed KTX train to other cities."
      },
      "q1": {
        "question": "How long is the flight from Seattle to Korea?",
        "answer": "From Seattle to Seoul, non-stop flights typically take 11 to 12 hours westbound and 10 to 10½ hours eastbound on the return. One-stop routes to Seoul or Busan usually last 14 to 18 hours total depending on the connection."
      },
      "q2": {
        "question": "Are there direct flights from Seattle to Korea?",
        "answer": "Yes, there are non-stop flights from Seattle to Korea. Korean Air and Delta Air Lines operate non-stop service from Seattle (SEA) to Seoul Incheon (ICN), with flight times around 11 to 12 hours westbound and slightly shorter eastbound due to prevailing winds. If you are traveling to other cities like Busan, you would typically connect in Seoul or another Asian hub, adding a few hours to your journey."
      },
      "q3": {
        "question": "Which airlines fly from Seattle to Korea?",
        "answer": "From Seattle to Korea you can fly Korean Air, Delta, Asiana, United, American, Alaska, Japan Airlines, ANA and other Asian carriers via their hubs."
      },
      "q4": {
        "question": "When is the cheapest time to fly from Seattle to Korea?",
        "answer": "The cheapest months to fly from Seattle to Seoul are September, October, and August, while peak summer (June) and December holidays see the highest fares. Midday departures tend to offer the lowest prices, and Monday is generally the cheapest day of the week to fly, with Friday and Saturday being the most expensive. Booking about 5–8 weeks ahead typically yields the best value, as last-minute tickets can climb significantly.",
        "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. The cheapest day of the week and time of day to depart are drawn from the same large sample of real fares Priceline users found on this route in the last 72 hours, grouped by the day of the week and by the time-of-day window of the outbound departure, with the lowest and average price reported for each."

      "q5": {
        "question": "How far in advance should I book flights from Seattle to Korea?",
        "answer": "For Seattle to Korea, the optimal booking window is about 5 to 8 weeks ahead, when average fares sit around $1,108 — roughly $250 less than last-minute prices.",

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. Where a median fare is shown for a carrier, it reflects the real fares Priceline users found on this route in the last 72 hours."

        "question": "What are the most popular cities to visit in Korea?",
        "answer": "Most visitors start in Seoul for its mix of tradition and modern buzz, then add coastal Busan, historic Gyeongju, the island of Jeju for nature, or the DMZ near Paju."
      },
      "q8": {
        "question": "Which airports in Korea are best to fly into from Seattle?",
        "answer": "From Seattle to South Korea, Incheon International Airport near Seoul is the primary and most convenient gateway, offering the most long‑haul options and excellent high‑speed train connections nationwide. Gimpo International also serves Seoul but handles mainly domestic and short‑haul regional flights, so it is less useful from the U.S. If your focus is Busan or the southern coast, look for flights connecting through Incheon or consider a separate domestic leg, as direct long‑haul service into Gimhae International in Busan is very limited."

      "q12": {
        "question": "When is the best time of year to visit Korea?",
        "answer": "For Korea, April to early June and September to early November provide comfortable weather and fewer crowds than the hot, humid summer months, with spring cherry blossoms and autumn foliage being highlights."
      },
      "q13": {
        "question": "How do I get to Seattle-Tacoma Intl Airport from the city center?",
        "answer": "The main public transit option from downtown Seattle to Sea-Tac Airport is the Link light rail, which takes about 40 minutes from Westlake Station and is often the most popular choice for its reliability and low cost. Rideshare services like Uber and Lyft, along with metered taxis, are available and provide a faster door-to-door trip in about 30–45 minutes, though they are more expensive. Several shuttle services also operate to the airport, and driving yourself is possible with various on-site parking options, though costs can add up for longer trips.",
