      },
      "q4": {
        "question": "When is the cheapest time to fly from San Francisco to El Salvador?",
        "answer": "The cheapest months to fly from San Francisco to El Salvador are April, May, and June, with September also offering lower fares; peak summer (July–August) and the December holiday period are notably more expensive. Midweek departures — especially Monday through Thursday — tend to be cheaper than Friday or Sunday, and late-night flights often offer the best value. Booking about 9 to 12 weeks ahead typically yields the lowest fares.",
        "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. 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. 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 El Salvador?",

      "q13": {
        "question": "How do I get to San Francisco Intl Airport from the city center?",
        "answer": "From downtown San Francisco, the fastest public option is BART, which runs directly from the city to the SFO International Terminal; you can board at any downtown BART station. Ride-share services like Uber, Lyft, and Wingz pick up on Level 5 of the Domestic Garage, while taxis are available at the center islands outside Arrivals. SamTrans bus Route 292 also stops directly at the airport terminals, and Caltrain connects via a BART transfer at Millbrae. Driving is another option, with on-site parking and a free Cell Phone Waiting Lot for pickups; BART is generally the most popular choice for avoiding traffic, though ride-share offers more door-to-door convenience at a higher cost.",
