        "question": "What is the typical flight duration from Washington D.C. to San Juan?",
        "answer": "A nonstop flight from Washington D.C. (DCA) to San Juan (SJU) typically takes about 3 hours 45 minutes to 4 hours. The return flight against headwinds can take roughly 4 hours 15 minutes to 4 hours 30 minutes. With one stop, common layovers include Charlotte or Miami, making the total travel time around 6 to 8 hours. American Airlines operates nonstop service from DCA, while other airlines may offer connections."

      "q1": {
        "question": "Are there any direct flights from Washington D.C. to San Juan?",
        "answer": "JetBlue is the only airline flying nonstop from Washington–National (DCA) to San Juan (SJU), operating one daily departure at 8:00 AM every day of the week. The schedule data shows a single daily flight with an on-time rate around 81% and a median fare near $226.",
        "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": "Luis Muñoz Marín International Airport (SJU) is about eight miles from Old San Juan and other central areas. Taxis are a fixed-rate option with set fares to zones like Old San Juan, Condado, and Isla Verde, taking roughly fifteen to twenty minutes depending on traffic. Ride-share services such as Uber and Lyft are available and generally cost slightly less than taxis, though they must pick up from a designated area near Terminal A. Public transit via buses and the Tren Urbano train is the cheapest but least convenient: the bus stop is a short walk from the terminal, but service is infrequent and requires a transfer to reach most tourist areas, taking forty-five minutes to over an hour. Car rentals are plentiful at the airport and useful for exploring beyond San Juan, but parking in Old San Juan is scarce and expensive. Most visitors use taxis or ride-shares for their directness and ease."

        "question": "When is the cheapest time to fly from Washington D.C. to San Juan?",
        "answer": "The cheapest months to fly from Washington D.C. to San Juan are August (around $369), September ($391), and May ($397), while the most expensive are December ($580), January ($480), and February ($475).",
        "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 Washington D.C. to San Juan?",
        "answer": "For flights from Washington D.C. (DCA) to San Juan (SJU), the optimal booking window is about 9 to 12 weeks before departure, with an average fare around $453 and the cheapest single fare at $450 around 80 days out. Booking last-minute can cost significantly more, with prices spiking to $589 if purchased on the day of travel. During peak summer and holiday periods, you should book even earlier—closer to 12 to 15 weeks ahead—as demand pushes fares higher and availability tightens.",
        "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": "There are no nonstop red-eye flights from Washington D.C. (DCA) to San Juan (SJU). However, connecting overnight options do exist — for example, via Orlando on Southwest departing around 9:20 PM and arriving in San Juan just after midnight, or via Fort Lauderdale on JetBlue departing around 9:15 PM and arriving just before midnight.",
        "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.",

This is the only carrier shown in the schedule data for nonstop service on this route. Other airlines may offer connecting flights via their hubs, but JetBlue is the primary nonstop option.",

      },
      "q9": {
        "question": "How reliable are on‑time departures on this route from Washington D.C. to San Juan?",
        "answer": "On-time performance is generally good, though afternoon thunderstorms or DCA congestion can cause delays. Early morning flights, particularly those operated by JetBlue or Southwest, tend to depart closer to schedule. DCA's perimeter rule limits nonstop options, so connecting flights may add variability. Booking the first departure of the day improves your odds."

      "q13": {
        "question": "How do I get to Ronald Reagan National Airport from the city center?",
        "answer": "From downtown D.C., the Metro's Yellow and Blue lines provide direct, affordable access to Reagan National in about 15–20 minutes, making it the most popular choice. Rideshares and taxis take 10–15 minutes but cost more. Driving and parking are available but expensive and often unnecessary."
