        "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, total travel time is usually between 6 and 8 hours, depending on the layover city. The return flight from San Juan to Detroit is often slightly shorter, averaging around 4 hours 20 minutes nonstop."
      },
      "q1": {
        "question": "Are there any direct flights from Detroit to San Juan?",
        "answer": "Yes, Delta flies nonstop from Detroit (DTW) to San Juan (SJU) daily, with two departures each day — one around 8:25 AM and another around 8:56 AM. Delta is the only airline offering nonstop service on this route.",
        "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. Where a median fare is shown for a carrier, it reflects the real fares Priceline users found on this route in the last 72 hours. 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 this route because Detroit, Michigan, and San Juan, Puerto Rico, are both within the United States. U.S. citizens and lawful permanent residents can travel freely with a valid government-issued ID. Non-U.S. citizens must carry valid immigration documents, but no additional visa is needed for this domestic flight."

        "question": "What are the ground transportation options in San Juan?",
        "answer": "At Luis Muñoz Marín International Airport (SJU), you can reach central San Juan by taxi, ride-share services like Uber, public bus (AMA), or rental car. Taxis and ride-shares are the fastest and most popular options, taking about 10–15 minutes to Condado or Old San Juan, while public buses are the cheapest at $0.75 but run less frequently. Car rentals are widely available for exploring beyond the city, though traffic and limited parking in historic areas can be a challenge.",

        "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 in late summer and early fall — August, September, and October — with average fares as low as $460. The most expensive months are December (averaging $710), March ($674), and June ($661), reflecting higher demand in winter and late spring.",
        "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 booking 10 to 13 weeks ahead, averaging around $573. Booking very close to departure can cost significantly more, with same-day tickets averaging $898.",
        "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.",

Frontier offers overnight connections via Orlando (departing 11:17 PM, arriving 2:15 AM), Dallas/Fort Worth (departing 11:01 PM, arriving 5:02 AM the next morning), and Philadelphia (departing 10:59 PM, arriving 2:59 AM).",
        "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.",

      },
      "q13": {
        "question": "How do I get to Detroit Metro Airport from the city center?",
        "answer": "From downtown Detroit, you can take the Detroit Air Xpress (DAX) bus, which runs daily from 3:30 a.m. to 11 p.m. and is the most popular public transit option; advance tickets cost $6. SMART buses (routes 125, 261, and 280) also serve the airport, but with more local stops. Ride‑share services like Uber and Lyft pick up curbside, taxis are available at designated stands, and driving yourself takes about 20–30 minutes via I‑94, with multiple on‑site parking choices. The DAX bus is often the fastest budget‑friendly choice, while ride‑share or a taxi offers door‑to‑door convenience at a higher cost.",
