        "question": "What is the typical flight duration from Chicago to San Juan?",
        "answer": "A nonstop flight from Chicago Midway (MDW) to San Juan (SJU) typically takes about 4 hours 30 minutes. Flights with one stop, often in cities like Orlando or Miami, usually range from 6 to 8 hours total travel time. The return flight from San Juan to Chicago Midway is often slightly shorter, around 4 hours 20 minutes nonstop."
      },
      "q1": {
        "question": "Are there any direct flights from Chicago to San Juan?",
        "answer": "Southwest flies nonstop from Chicago Midway to San Juan on Saturdays and Sundays, with departures around 8:35 and 8:40 in the morning. It's the only airline offering nonstop service on this route, and flights don't run daily — just those two weekend days each week.",
        "methodology": "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": "At San Juan's Luis Muñoz Marín Airport (SJU), taxis, rideshares, car rentals, and public buses are available. The most-used option is the taxi, with a fixed-rate stand outside baggage claim; it's the fastest way to Old San Juan or Condado, taking about 10–15 minutes. Ridesharing services like Uber also operate, but pickup can be slightly less convenient than the taxi line. Public buses (AMA) are the cheapest at $0.75 but are slow and not recommended with luggage. Car rentals are plentiful for exploring beyond the city, though traffic and parking in Old San Juan can be challenging.",

        "question": "When is the cheapest time to fly from Chicago to San Juan?",
        "answer": "The cheapest time to fly from Chicago Midway to San Juan is late summer through early fall, with August offering the lowest average fares around $365, followed by September and May. The most expensive months are December and March, when average prices climb above $630.",
        "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.",

      "q5": {
        "question": "How far in advance should I book tickets from Chicago to San Juan?",
        "answer": "For Chicago (MDW) to San Juan (SJU), the best fares appear when booking 8 to 11 weeks ahead, averaging around $457. Prices tend to rise sharply within the final two weeks, and while summer and holiday periods likely push the optimal window slightly earlier, the core 8-11 week range remains a solid target for this route.",
        "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.",

        "answer": "No nonstop red‑eye flights operate from Chicago Midway to San Juan. One connecting overnight itinerary appears in the schedule: a United flight departing Houston (IAH) at 11:56 PM and arriving San Juan at 5:29 AM, with a short layover in Houston after the inbound from Chicago.",
        "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.",

        "question": "Which airlines usually operate this route from Chicago to San Juan?",
        "answer": "Southwest Airlines operates nonstop from Chicago Midway to San Juan, with three flights per week on Saturdays and Sundays. The median fare on this route is around $341.",
        "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.

        "answer": "Common layover cities between Chicago Midway and San Juan include Atlanta, Orlando, Fort Lauderdale, and Tampa. These hubs offer numerous daily flights, efficient connections, and often competitive total travel times on airlines like Southwest and Delta. Since this is a domestic route within the US, visa‑free transit is irrelevant."
      },
      "q9": {
        "question": "How reliable are on‑time departures on this route from Chicago to San Juan?",
        "answer": "On‑time performance varies, with afternoon and evening flights more prone to delays. Opting for early morning departures on Southwest typically yields better reliability."

        "question": "Which months have the best weather for traveling to San Juan?",

      },
      "q11": {
        "question": "What documents should I bring with me to the airport when flying from Chicago to San Juan?",
        "answer": "Since Puerto Rico is a U.S. territory, this is a domestic flight. Bring a Real ID-compliant driver's license or passport, a payment method for baggage, and any required health documents. No visa or passport validity beyond standard ID rules is needed."
      },

        "question": "Which airport should I use in San Juan?",
        "answer": "San Juan has one main airport, Luis Muñoz Marín International Airport, which handles all commercial flights."

      "q13": {
        "question": "How do I get to Midway Intl Airport from the city center?",
        "answer": "The CTA Orange Line 'L' train is the fastest and most popular way to reach Midway from downtown Chicago, with a station right at the airport. Taxis offer a convenient door-to-door option with metered fares, while rideshare services like Uber and Lyft pick up on the lower level outside baggage claim. Several airport shuttles and regional buses also serve the airport, and driving is straightforward with hourly, daily, and economy parking available. Public transit is the cheapest option, rideshares and taxis cost more, and parking rates vary by lot.",
