        "answer": "From Chicago you typically fly into Belgrade Nikola Tesla Airport, the country's main international gateway. There are no non-stop flights, so you will connect through a European hub like Frankfurt, Istanbul or Vienna. Once in Belgrade, you can reach other cities such as Novi Sad or Niš by bus or train. Belgrade suits most travelers as a base for exploring Serbian culture and nightlife."

        "question": "When is the cheapest time to fly from Chicago to Serbia?",
        "answer": "The cheapest months to fly from Chicago to Serbia are January, February, October, and November, when average fares are lowest. Book about 23 to 26 weeks ahead for the best price, and aim for midweek departures if your schedule allows, since midweek flights tend to be cheaper than weekends. Peak summer months like June and July, as well as the December holiday season, are typically the most expensive times to 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."

        "question": "How far in advance should I book flights from Chicago to Serbia?",
        "answer": "For flights from Chicago to Serbia, the optimal booking window is 23–26 weeks ahead, when average fares hover around $875, though the cheapest single fare appears at 180 days out ($808); summer and holiday travel (May–July, December) should be booked earlier in that window, while shoulder and off-peak months (January–February, October–November) can sometimes be booked a bit closer in.",

Niš Constantine the Great Airport offers fewer options and is useful mainly if your final destination is in southern Serbia, but you will likely need to connect through another European city first."
