        "question": "Which cities in Puerto Rico can I fly to from St Louis?",
        "answer": "From St. Louis you will connect through a U.S. hub to fly into San Juan, the main gateway. Some itineraries also serve Aguadilla or Ponce, but San Juan offers the most flights and is best for exploring the island or catching a short flight to Vieques or Culebra."

      "q4": {
        "question": "When is the cheapest time to fly from St Louis to Puerto Rico?",
        "answer": "The cheapest months to fly from St. Louis to Puerto Rico are September, October, August, and November, with late summer and early fall offering the lowest fares, while peak summer and the December holiday season are the most expensive. Booking about 23 to 26 weeks ahead (roughly 5–6 months) typically yields the best prices on this route. Although departure-timing data is unavailable for this route, midweek flights (Tuesday/Wednesday) and early-morning or late-night departures generally offer better value than weekend and midday travel.",
        "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."

      "q5": {
        "question": "How far in advance should I book flights from St Louis to Puerto Rico?",
        "answer": "For flights from St. Louis to Puerto Rico, the optimal booking window is about 23 to 26 weeks ahead of departure, when average fares are around $514, though you might catch the lowest prices around 125 days out at roughly $487.",

        "question": "What are the most popular cities to visit in Puerto Rico?",
        "answer": "In Puerto Rico, San Juan is the main entry with historic Old San Juan and vibrant culture. From there, explore the rainforest and beaches of the east coast around Fajardo, the surf and relaxed vibe of Rincón on the west coast, and the bioluminescent bay in Vieques or the nature of Culebra island."

      "q7": {
        "question": "Do I need a visa to travel from St Louis to Puerto Rico?",
        "answer": "As a U.S. citizen flying from St. Louis to Puerto Rico, you do not need a visa or any electronic travel authorization because Puerto Rico is a U.S. territory. This is treated as a domestic trip, so you just need a valid government-issued ID for air travel. Rules can change, but currently no special entry documents are required."
      },
      "q8": {
        "question": "Which airports in Puerto Rico are best to fly into from St Louis?",
        "answer": "From St. Louis to Puerto Rico, you will almost always fly into San Juan Luis Muñoz Marín International Airport, which handles all long-haul flights from the mainland U.S. and offers the best connections for regional travel, car rentals, and cruise ports. Aguadilla and Ponce have limited mainland service and are less practical from St. Louis."
      },
      "q12": {
        "question": "When is the best time of year to visit Puerto Rico?",
        "answer": "For Puerto Rico, mid-December to April offers the most reliable dry weather, though prices peak in winter. May to June and November provide a good balance of lower rates and decent conditions before the wetter hurricane season."
