        "question": "What is the typical flight duration from Detroit to San Juan?",
        "answer": "A nonstop flight from Detroit (DTW) to San Juan (SJU) typically takes about 4 hours 30 minutes to 4 hours 45 minutes. With one stop, common layover cities include Atlanta (ATL), Charlotte (CLT), or Miami (MIA), bringing total travel time to roughly 6 to 8 hours. Return flights often have similar durations, but some westbound flights may be slightly shorter due to prevailing winds. Delta and Spirit offer nonstop service on this route."

      "q1": {
        "question": "Are there any direct flights from Detroit to San Juan?",
        "answer": "Delta offers the only nonstop flights from Detroit (DTT) to San Juan (SJU), operating twice daily every day of the week with departures around 8:25 AM and 8:56 AM.",
        "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": "Are there visa requirements to travel from Detroit to San Juan?",
        "answer": "No visa is required for U.S. citizens traveling from Detroit to San Juan because Puerto Rico is a U.S. territory and the flight is domestic. Non-U.S. citizens should carry the same documentation they used to enter the United States, as this is a domestic flight and no additional visa is needed."

      "q3": {
        "question": "What are the ground transportation options in San Juan?",
        "answer": "San Juan's Luis Muñoz Marín International Airport (SJU) is about 3 miles from the city center. Taxis are readily available and operate on fixed zone-based rates, taking around 10-15 minutes to reach central areas like Condado or Old San Juan. Ride-share services such as Uber are legal and widely used, often providing lower fares than taxis. Public buses are the cheapest option but are slow, infrequent, and not recommended for visitors with luggage. Car rentals are available at the airport and useful for exploring the island, but parking in Old San Juan is difficult and expensive. There is no direct rail link from the airport. Most travelers use ride-share or taxis for their convenience and speed."
      },
      "q4": {
        "question": "When is the cheapest time to fly from Detroit to San Juan?",
        "answer": "The cheapest time to fly from Detroit to San Juan is late summer into early fall, with the lowest average fares in August ($500), September ($514), and October ($525); July ($548) is also relatively affordable. The most expensive period is winter through early spring, especially December ($742), March ($669), and February ($662), with January ($649) also in the high season.",
        "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 Detroit to San Juan?",
        "answer": "For flights from Detroit to San Juan, the best fares are typically found when booking 10 to 13 weeks ahead, with an average price around $579 during that window. Booking about 165 days out can occasionally yield the lowest fare at $574, while last-minute tickets can spike to $900 — so for summer or holiday travel, aim to book on the earlier side of that range, around 13 weeks or more in advance.",
        "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.",

Connecting itineraries exist where the overnight leg is operated by Frontier (F9) via Philadelphia, Orlando, or Dallas/Fort Worth, with typical departure times between roughly 11 PM and midnight and arrivals in San Juan between about 2 AM and 5 AM the next morning.",
        "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.",
