      "q4": {
        "question": "When is the cheapest time to fly from Chicago to Puerto Rico?",
        "answer": "The cheapest months to fly from Chicago to Puerto Rico are August, September, and May, while December and March are the most expensive; peak summer and major holidays tend to cost more. Booking 8 to 11 weeks ahead typically yields the best fares, and departing on a Tuesday or a late-night flight often saves money compared to Thursday or Friday departures.",
        "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": "How do I get to Dupage County from the city center?",
        "answer": "DuPage Airport (DPA) is a general aviation field in West Chicago, about 30 miles west of downtown, and there is no direct public transportation link; you'd need to drive or take a ride-share/taxi from the Loop. Driving via I-290/I-88 is the fastest and most common option, with on-site parking available at the airport's FBO, while ride-share and taxis are also possible but cost more than driving. No shuttle buses or scheduled transit serve the airport, so a private car or hired ride is essentially required.",
