        "question": "When is the cheapest time to fly from San Francisco to United Kingdom?",
        "answer": "The cheapest months to fly from San Francisco to the United Kingdom are April, October, and November, while peak summer (June–July) and December holidays are the most expensive. Booking about 23–26 weeks ahead (roughly 5–6 months) tends to yield the best fares. Midweek departures, especially Wednesday, are cheaper than weekends, and afternoon flights often have the lowest prices.",
        "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 San Francisco to United Kingdom?",
        "answer": "For flights from San Francisco to the United Kingdom, the best time to book is about 23 to 26 weeks ahead, when fares average around $903 — booking too close to departure or more than six months out tends to cost more.",

SamTrans buses (Route 292 and late-night ECR Owl/397) provide 24/7 public bus service to the airport, while shared airport shuttles like Marin Airporter serve Marin County and other areas. Ride-share pickups for Lyft, Uber, and Wingz are located on Level 5 of the Domestic Garage, and taxis wait at the center islands outside Arrivals. Driving and parking is also an option, with long-term and terminal garages accessible via AirTrain, and a free cell phone waiting lot for pickups.",
