        "question": "What is the typical flight duration from Jacksonville to San Juan?",
        "answer": "A nonstop flight from Jacksonville (JAX) to San Juan (SJU) typically takes about 3 hours 10 minutes to 3 hours 20 minutes. With one stop, common layovers include Miami (MIA) or Atlanta (ATL), bringing total travel time to roughly 5 to 7 hours. The return flight from San Juan to Jacksonville is similar in duration, often around 3 hours 15 minutes nonstop."
      },
      "q1": {
        "question": "Are there any direct flights from Jacksonville to San Juan?",
        "answer": "Yes, Frontier (F9) offers non‑stop flights from Jacksonville (JAX) to San Juan (SJU), operating on Monday, Wednesday, Thursday, Friday, Saturday, and Sunday — no Tuesday service — with up to three daily departures around 11:21 AM, 2:40 PM, and 7:07 PM. Frontier is the only airline shown flying this route non‑stop in the schedule data.",
        "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": "San Juan's Luis Muñoz Marín International Airport (SJU) is about three miles from the city center. Taxis are readily available outside the terminals and use fixed rates to zones like Old San Juan, Isla Verde, and Condado, making them a reliable and popular choice. Ride-share services such as Uber are also available, though pickup areas may be designated. Public buses are the cheapest option but are infrequent, slow, and not recommended for travelers with luggage. Car rentals are widely available at the airport and useful for exploring the island, but parking in Old San Juan is difficult and expensive. Shuttle services and private transfers can be pre-booked. Most visitors use taxis or ride-shares for their convenience and direct service."

      "q4": {
        "question": "When is the cheapest time to fly from Jacksonville to San Juan?",
        "answer": "The cheapest months to fly from Jacksonville to San Juan are September (average $318), May ($334), and August ($339), while the most expensive are December ($506), March ($480), and January ($462).",
        "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 Jacksonville to San Juan?",
        "answer": "For the Jacksonville to San Juan route, the optimal booking window is roughly 21 to 24 weeks (about 5 to 6 months) in advance, with an average fare around $392. Booking around 170 days ahead can yield the lowest individual price at $385, while last-minute purchases (less than a week out) can spike to $563 or more. During summer and holiday peaks, demand may push the ideal window slightly earlier, so aiming for 24 weeks out is a safe bet.",
        "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.",

        "question": "Are overnight (red‑eye) flights available from Jacksonville to San Juan?",
        "answer": "There are no nonstop red-eye flights from Jacksonville (JAX) to San Juan (SJU). A search did turn up one connecting itinerary where the long leg — Fort Lauderdale (FLL) to San Juan on JetBlue, departing at 9:15 PM and arriving at 11:57 PM — is an overnight flight, but that requires a very long layover in Fort Lauderdale and is not a practical nonstop red-eye option.",
        "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.",

Other carriers may also serve the route with connecting itineraries, but the nonstop option is exclusively Frontier based on the available schedule.",

        "answer": "Common layover cities for this route include Miami, Atlanta, Charlotte, and Orlando. Miami offers the most direct southerly routing and frequent flights, keeping total travel time competitive. Atlanta provides a vast network with many onward connections to San Juan. Charlotte is a major hub with efficient transfers, and Orlando offers a shorter first leg while still providing good connectivity. All are domestic connections, so no visa concerns apply."

Connecting itineraries most often involve American Airlines via Miami on Boeing 737-800 or Airbus A321-100 long legs, or JetBlue via Fort Lauderdale on Airbus A320-100 equipment; the exact aircraft can vary by day and airline.",
