        "question": "When is the cheapest time to fly from Chicago to Portugal?",
        "answer": "The cheapest months to fly from Chicago to Portugal are March, April, October, and November, with March and November offering the lowest fares, while peak summer (June–July) and May are the most expensive. Booking about 8 to 11 weeks ahead tends to yield the best prices, and midweek departures generally beat weekend flights. Peak summer and major holidays like Christmas push fares higher, so traveling in the shoulder or low season and avoiding Fridays and Sundays will help keep costs down.",
        "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 Chicago to Portugal?",
        "answer": "For flights from Chicago to Portugal, the ideal booking window is about 8 to 11 weeks before departure, though you'll want to book further ahead for summer and holiday travel when prices tend to climb earlier.",
