      "q4": {
        "question": "When is the cheapest time to fly from Denver to Puerto Rico?",
        "answer": "The cheapest months to fly from Denver to Puerto Rico are October, September, and August, with fares typically lowest in October. Midweek departures — especially Wednesday — tend to be cheaper than weekend flights, and late-night departures often offer the best prices. Booking about 9 to 12 weeks ahead usually yields the lowest fares, while peak summer and major holidays like December see noticeably higher prices.",
        "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."

      "q5": {
        "question": "How far in advance should I book flights from Denver to Puerto Rico?",
        "answer": "For flights from Denver to San Juan, the optimal booking window is around 9 to 12 weeks before departure, when fares average about $678, though you can sometimes find the lowest prices by booking roughly 80 days out.",

Stop counts, connecting hubs, and per-airline prices are drawn from a large sample of the real fares Priceline users found on this route in the last 72 hours. We group those fares by number of stops, by the hub airport a connection routes through, and by operating airline, and report each group's share of the sample alongside its lowest and median price."

        "question": "Do I need a visa to travel from Denver to Puerto Rico?",
        "answer": "As a United States citizen or national, you do not need a visa to travel from Denver to Puerto Rico. Puerto Rico is part of the United States, so entry is by right for U.S. nationals and there is no visa requirement or permitted length of stay applicable. You can travel freely as you would between any two U.S. destinations.\n\nThis is general guidance to help you plan, not official immigration advice — entry rules can change and can depend on your nationality and circumstances, so please confirm the current requirements with the relevant embassy or official government source before you travel.",

      "q13": {
        "question": "How do I get to Denver Intl Airport from the city center?",
        "answer": "From downtown Denver, the RTD A Line commuter train is the fastest and most popular public option, whisking you to the airport in about 37 minutes with trains running every 15 minutes around the clock. Ride-share services like Uber and Lyft, along with taxis, offer convenient door-to-door pickup from Level 5 and take roughly 25–35 minutes, though they cost more than the train. Shared shuttles and hotel shuttles serve many downtown hotels for a mid-range price, and driving yourself is possible with both on-site parking and off-site rental car facilities, but parking fees add up for longer trips.",
