        "question": "When is the cheapest time to fly from San Francisco to Puerto Rico?",
        "answer": "The cheapest months to fly from San Francisco to Puerto Rico are September, August, and October, while December and June are the most expensive; midweek departures, especially Monday, tend to be cheaper than later in the week. Late-night and evening flights generally offer the lowest fares, and booking about 22 to 25 weeks (roughly 5 to 6 months) ahead typically yields the best prices. Peak summer and major holidays like the December holiday season are usually 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. 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."

        "question": "Do I need a visa to travel from San Francisco to Puerto Rico?",
        "answer": "Since Puerto Rico is a U.S. territory, U.S. citizens do not need a visa or electronic travel authorization for travel from San Francisco.

        "answer": "From San Francisco to Puerto Rico, Luis Muñoz Marín International Airport in San Juan is the primary gateway with the most long-haul options and connections to the Caribbean. For regional travel or a quieter start, Rafael Hernández Airport in Aguadilla serves the west coast and works well for beach resorts, while Mercedita Airport in Ponce handles limited flights and suits southern destinations. Most flights from SFO connect through East Coast hubs, and San Juan offers the best mix of rental cars, taxis, and regional flights for onward travel."

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

Late spring, particularly May, and autumn, especially October and November, bring lower fares and fewer tourists while still providing pleasant conditions, though there is a higher chance of rain."
