        "question": "What is the typical flight duration from Des Moines to San Juan?",
        "answer": "There are no nonstop flights from Des Moines (DSM) to San Juan (SJU). Typical one-stop flights take around 7 to 9 hours total travel time, with common layovers in Chicago (ORD), Atlanta (ATL), Dallas (DFW), or Charlotte (CLT). The return flight from San Juan to Des Moines usually takes a similar duration, roughly 7 to 9 hours, depending on layover length and direction of connections."

      "q1": {
        "question": "Are there any direct flights from Des Moines to San Juan?",
        "answer": "There are no nonstop flights from Des Moines (DSM) to San Juan (SJU). The shortest connecting routings are via Chicago O'Hare (ORD) on American or United, with the first leg around 100–102 minutes and the second leg around 295–298 minutes, plus a layover of about 69–153 minutes, making total travel time roughly 8 to 9 hours.",
        "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.",

        "question": "Are there visa requirements to travel from Des Moines to San Juan?",
        "answer": "No visa is required for this route. Des Moines, Iowa is in the United States, and San Juan, Puerto Rico is a U.S. territory. Travel between the two is domestic, so U.S. citizens only need a valid government-issued ID. Non-U.S. citizens should carry their valid U.S. visa or resident documentation, as they remain within U.S. jurisdiction."

      "q3": {
        "question": "What are the ground transportation options in San Juan?",
        "answer": "From Luis Muñoz Marín International Airport (SJU) to San Juan’s city center, taxis are the most used and convenient option, with a fixed fare to destinations like Old San Juan or Condado. Ride-share services such as Uber are available but may have designated pickup areas. Public buses (AMA) serve the airport via route T5 or D53, connecting to the Tren Urbano rail system, but they are infrequent and not recommended for visitors with luggage. Car rentals are widely available at the airport and are useful for exploring beyond San Juan, though parking in Old San Juan is limited. Shared shuttle vans also operate but require advance booking. Taxis are generally preferred for their reliability and set rates."

      "q4": {
        "question": "When is the cheapest time to fly from Des Moines to San Juan?",
        "answer": "Based on pricing data for the Des Moines to San Juan route, the cheapest months to fly are September (average $570), October ($587), and August ($601), while the most expensive are December ($772), March ($693), and June ($685).",
        "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 Des Moines to San Juan?",
        "answer": "For flights from Des Moines to San Juan, the best fares are typically found when booking 19 to 22 weeks ahead, averaging $628, though the absolute cheapest price in the data appears around 135 days out at $597. During peak summer or holiday periods, prices tend to rise, so booking even earlier within that window or slightly beyond can help avoid last-minute spikes, which can exceed $800.",
        "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.",

        "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.",
