      "q4": {
        "question": "When is the cheapest time to fly from San Francisco to Korea?",
        "answer": "The cheapest months to fly from San Francisco to Korea are August, September, and November, with August averaging the lowest fares; late spring and early summer (May–June) and the December holiday period are the most expensive. Booking about 8 to 11 weeks ahead typically yields the best prices, and while midweek and off-peak departure times often help on long-haul routes, peak summer and major holidays will almost always be pricier.",
        "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."
      },
      "q5": {
        "question": "How far in advance should I book flights from San Francisco to Korea?",
        "answer": "For flights from San Francisco to Korea, the optimal booking window is 8 to 11 weeks ahead of departure, when average fares hover around $991, with the single cheapest day typically at 65 days out near $983; prices climb noticeably inside 4 weeks and spike above $1,200 at the last minute.",

        "question": "When is the best time of year to visit Korea?",

      },
      "q13": {
        "question": "How do I get to San Francisco Intl Airport from the city center?",
        "answer": "BART rapid rail is the fastest and most popular way to reach San Francisco International Airport from downtown, running directly from the city center to the airport's International Terminal with frequent service. Ride-share services like Uber, Lyft, and Wingz pick up at Terminal 5 of the Domestic Garage, while taxis are available at the center islands outside Arrivals, both offering door-to-door convenience at a higher cost than public transit. SamTrans public buses (Route 292 and overnight routes) provide a low-cost option, and driving is possible with on-airport parking garages and long-term lots, though parking fees make it the priciest choice.",
