        "answer": "From Louisville you will connect through a major hub to reach San Juan, the main gateway. San Juan has the best flight options and serves as a base for exploring the island. Smaller airports in Aguadilla and Ponce are available but require extra connections and are less frequent."

      },
      "q4": {
        "question": "When is the cheapest time to fly from Louisville to Puerto Rico?",
        "answer": "The cheapest months to fly from Louisville to San Juan are September, October, and August, while peak summer (June–July) and the December holidays are the most expensive. Midweek departures — especially Monday — tend to be cheaper than Thursday or Friday, and early morning flights offer the lowest fares. For the best price, book about 9 to 11 weeks before your trip.",
        "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 Louisville to Puerto Rico?",
        "answer": "For flights from Louisville to San Juan, the best time to book is about 9 to 11 weeks before departure, when fares average around $468 round-trip.",

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."

        "question": "What are the most popular cities to visit in Puerto Rico?",

        "question": "How do I get to Muhammad Ali Intl Airport from the city center?",
        "answer": "Getting to Louisville Muhammad Ali International Airport (SDF) from downtown is easiest by car, taxi, or ride-share, as the airport sits about 6.5 miles south of the city center and is well-connected by Interstates 64, 65, and 71. Public transit is available via TARC buses, though the route may require a transfer and is generally slower than driving. There are no dedicated airport shuttle buses, but ride-share and taxis offer door-to-door convenience and are the most popular choice for travelers. Driving yourself is also straightforward, with on-site parking garages available at the terminal.",
