Uber and Lyft operate in the area and are widely used, often at a slightly lower cost than official airport taxis. Rental cars are available at the airport, but parking in the historic center is limited and generally unnecessary for short stays.

October also offers low prices around $316, while the most expensive period is December, when average fares climb to $477.", "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.", "toolsUsed": ["seasonal_prices"]}, "q5": {"question": "How far in advance should I book tickets from Jacksonville to San Juan?", "answer": "For the Jacksonville to San Juan route, the best fares are typically found when booking 9 to 12 weeks ahead, with an average price around $391. The absolute lowest fare of $387 appears around 80 days before departure, while waiting until the last minute can push prices up to $565. This window may shift earlier for peak summer and holiday periods, when demand often drives prices higher and inventory tighter.", "methodology": "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.
