        "question": "What is the typical flight duration from Chicago to San Juan?",
        "answer": "A nonstop flight from Chicago (MDW) to San Juan (SJU) typically takes about 4 hours 30 minutes to 4 hours 45 minutes, operated by Southwest. With one stop, total travel time often ranges from 6 to 8 hours, depending on the layover city. The return flight is generally similar in duration."
      },
      "q1": {
        "question": "Are there any direct flights from Chicago to San Juan?",
        "answer": "From Chicago Midway (MDW) to San Juan (SJU), Southwest Airlines offers non‑stop flights three times a week — on Saturdays and Sundays, with Saturday departures at 8:35 AM and 8:40 AM and a Sunday departure at 8:40 AM. It's the only airline flying this route non‑stop, so service is limited to those two weekend days.",
        "methodology": "Airlines and weekly frequencies are compiled from our flight-schedule database, which combines published airline timetables, U.S. government schedule data from the Bureau of Transportation Statistics (BTS), and observed flight operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI). We count each operating carrier's scheduled weekly departures and the days it flies; where there is no nonstop service, connecting carriers are identified by linking scheduled nonstop segments through common hub airports. Carrier service and weekly frequencies are summarized from our flight-schedule database, which draws on published airline timetables, U.S. government schedule data, and observed operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI). Where available, on-time and cancellation rates come from the U.S. Bureau of Transportation Statistics (BTS) Airline On-Time Performance dataset, and typical fares from the U.S. DOT Airline Origin and Destination Survey (DB1B), a quarterly 10% sample of tickets sold.",

        "question": "What are the ground transportation options in San Juan?",
        "answer": "From Luis Muñoz Marín International Airport (SJU) to central San Juan, taxis and ride-sharing services like Uber are the most convenient and widely used options, with a typical trip of about fifteen minutes to areas like Condado or Old San Juan. Taxis operate on a fixed-rate zone system from the airport. Public bus route T5 connects the airport to the Tren Urbano light rail at Sagrado Corazón station, from which you can reach other parts of the metro area, but this option is slower and less popular due to frequency and coverage limitations. Car rentals are available at the airport and are recommended if you plan to explore beyond San Juan, though parking in Old San Juan is scarce and expensive. Shared shuttle services and private transfers can also be pre-arranged. For most visitors, taxis or ride-shares offer the best balance of speed, simplicity, and door-to-door service."

      "q4": {
        "question": "When is the cheapest time to fly from Chicago to San Juan?",
        "answer": "Based on seasonal price data for flights from Chicago (MDW) to San Juan (SJU), the cheapest months to fly are August (average $362), April ($403), and May ($411), with the low season generally spanning August, April, May, and September. The most expensive months are December (average $674), January ($598), and February ($596), with the high season covering November, February, January, and December.",
        "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.",

        "question": "How far in advance should I book tickets from Chicago to San Juan?",
        "answer": "For flights from Chicago (MDW) to San Juan (SJU), the optimal booking window is roughly 9 to 12 weeks before departure, with an average fare around $486. Booking about 75 days out can yield the lowest price around $479, while last-minute tickets can spike to $658 or more, especially during peak summer and holiday periods when demand is higher.",
        "methodology": "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": "Are overnight (red‑eye) flights available from Chicago to San Juan?",
        "answer": "There are no nonstop red-eye flights from Chicago Midway (MDW) to San Juan (SJU). Connecting itineraries with an overnight leg do exist — for example, via Orlando on Southwest with the overnight leg departing around 9:20 PM and arriving around 12:20 AM, or via Dallas-Fort Worth on Frontier departing around 11:01 PM and arriving around 5:02 AM — but no direct overnight service is available.",
        "methodology": "Red-eye flights are identified from scheduled local departure and arrival times in our flight-schedule database — built from published airline timetables and official schedule data, including U.S. Department of Transportation records for domestic routes — flagging services that depart late at night and arrive the following morning; for connecting itineraries the red-eye is based on the timing of the overnight long-haul leg.",

The flights depart in the morning, around 8:35 or 8:40 AM. Other carriers may offer connecting options, but Southwest is the only nonstop carrier shown in the schedule data.",
