        "answer": "From Chicago to San Salvador, non-stop flights take about 4 hours 30 minutes to 5 hours, with the return flight often slightly longer due to headwinds. One-stop itineraries typically range from 6 to 9 hours total travel time depending on layover duration and routing."

      "q4": {
        "question": "When is the cheapest time to fly from Chicago to El Salvador?",
        "answer": "The cheapest months to fly from Chicago to El Salvador are April, May, September, and October, while December and the summer months are the most expensive. Booking about 9 to 12 weeks ahead tends to yield the best fares, and midweek departures are generally cheaper than weekends. Peak summer and major holidays like Christmas push prices significantly higher.",
        "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 El Salvador?",
        "answer": "For flights from Chicago to El Salvador, the optimal booking window is about 9 to 12 weeks ahead, when average fares drop to around $492, with the very lowest prices appearing roughly 70 days before departure.",

        "question": "Which airports in El Salvador are best to fly into from Chicago?",
        "answer": "From Chicago to El Salvador, you will almost certainly fly into Monseñor Óscar Arnulfo Romero International Airport in San Salvador. It is the country's only international airport receiving flights from the U.S. and handles all long-haul traffic. There are no train services, but the airport is well connected by road to the capital and coastal resorts."

        "question": "When is the best time of year to visit El Salvador?",
        "answer": "El Salvador's best weather is in the dry season, November to March, with sunny skies and lower humidity. Summer is rainy season, so prices are lower but expect daily downpours. Spring and autumn are transitional and can be a good compromise."

      "q13": {
        "question": "How do I get to Dupage County from the city center?",
        "answer": "DuPage Airport (DPA) in West Chicago is a general aviation reliever airport, so public transit options from downtown Chicago are limited—there is no direct CTA 'L' or Metra service to the airport itself. Most travelers reach it by driving or taking a taxi/ride-share, which is the fastest and most popular method, with parking available on-site and at nearby FBOs. Pace suburban buses serve the broader DuPage County area but do not stop at the airport terminal, so a short taxi or ride-share connection from a nearby Pace stop is possible, though less convenient. Driving is generally the most practical and cost-effective option for groups, while solo travelers may find ride-share competitive for short trips.",
