        "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 September, August, and October, while December, June, and January are the most expensive — peak summer and major holidays tend to push prices up. For the best fare, book about 6 to 9 weeks before departure, when prices are lowest; last-minute bookings and buying more than 3 months out both cost more. Midweek departures often offer better value than weekends on long-haul routes like this, though specific day-of-week data wasn't available for SFO–Seoul.",
        "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 San Francisco to Korea?",
        "answer": "For flights from San Francisco to Korea, the optimal booking window is about 6 to 9 weeks before departure, when average fares drop to around $1,065.",

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."

Gimpo International in Seoul handles domestic flights and short regional hops. For southern beach resorts or Jeju Island, flying into Gimhae International in Busan or Jeju International can be convenient, though you will typically connect through Incheon from San Francisco."
