        "question": "When is the cheapest time to fly from Belgrade to United States?",
        "answer": "The cheapest months to fly from Belgrade to the United States are January, October, and November, when average fares are lowest, while peak summer (June–July) and May are the most expensive. Booking about 23 to 26 weeks ahead tends to yield the best fares, and although midweek and off-peak departure times typically help, avoiding summer and major holidays will 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. For this route, fares for the requested travel direction were unavailable, so the pattern shown is derived from the reverse direction, which shares the same seasonal demand cycle."

      "q5": {
        "question": "How far in advance should I book flights from Belgrade to United States?",
        "answer": "For flights from Belgrade to the United States, the optimal booking window is 23 to 26 weeks ahead, when average fares drop to around $962, though booking as early as 180 days out can yield the lowest price of about $725; summer and holiday travel (May–July) sees the steepest fares, while January, October, and November are the cheapest months to fly.",

For the East Coast, New York JFK and Newark offer the most frequent connections. For the Midwest, Chicago O'Hare is a major hub with extensive domestic flights.

      "q13": {
        "question": "How do I get to Nikola Tesla Airport from the city center?",
        "answer": "From downtown Belgrade, public bus line 72 runs from Zeleni Venac directly to Nikola Tesla Airport and is the most popular and budget-friendly option. Taxis and ride-share services offer a faster, door-to-door trip for a higher cost, while driving yourself is possible but parking at the airport adds expense and hassle. A dedicated airport shuttle bus is not currently advertised, so the regular city bus or a private car are the main choices.",
