        "answer": "A nonstop flight from Charleston (CHS) to San Juan (SJU) typically takes about 3 hours 15 minutes to 3 hours 30 minutes. With one stop, depending on the connecting city, total travel time usually ranges from 5 to 7 hours."
      },
      "q1": {
        "question": "Are there any direct flights from Charleston to San Juan?",
        "answer": "There are no nonstop flights from Charleston (CHS) to San Juan (SJU). The most frequent one-stop option is on American Airlines via Charlotte (CLT), with the first leg taking about 1 hour 15 minutes, a layover around 1 hour 40 minutes, and the second leg about 3 hours 45 minutes, for a total travel time of roughly 6½ hours. American also connects through Miami, while United offers connections via Dulles, Newark, or Chicago, and JetBlue via Fort Lauderdale or JFK, though those appear less frequently.",
        "methodology": "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. 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. 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.",

        "question": "Are there visa requirements to travel from Charleston to San Juan?",
        "answer": "No visa is required for this route because the flight is entirely within the United States. Puerto Rico is a U.S. territory, and travel between Charleston, South Carolina, and San Juan, Puerto Rico, is domestic. U.S. citizens and lawful permanent residents can travel without a passport or visa. Non‑U.S. citizens who are legally in the United States must carry valid identification and any required U.S. immigration documents, but no additional visa is needed for this domestic flight."

        "question": "What are the ground transportation options in San Juan?",
        "answer": "From Luis Muñoz Marín International Airport (SJU), taxis and ride-shares like Uber are the most popular and quickest ways to reach San Juan's city center, with a typical drive of 15–25 minutes to areas like Old San Juan or Condado. Public buses operated by the AMA are available via route T5 or D53 but are slower and less convenient, with a fare of $0.75. Car rentals are widely available at the airport for those wanting flexibility to explore beyond the city. There is no direct rail link from the airport, though you can connect to the Tren Urbano via bus for a combined transit option. Taxis and ride-shares are the most used by visitors for their door-to-door ease.",

        "question": "When is the cheapest time to fly from Charleston to San Juan?",
        "answer": "The cheapest months to fly from Charleston to San Juan are September, August, and October, with average fares as low as $408 in September. The most expensive months are December, March, and June, with December averaging $643.",
        "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 Charleston to San Juan?",
        "answer": "For Charleston to San Juan, the best fares are typically found when booking 10 to 13 weeks ahead, with an average of $445 in that window. The absolute cheapest single day to book is around 85 days out at $436, while last-minute tickets can spike to $746. For summer or holiday travel, you'll want to book even earlier, as peak demand often pushes the ideal window out by a few weeks.",
        "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": "How reliable are on‑time departures on this route from Charleston to San Juan?",

        "question": "What documents should I bring with me to the airport when flying from Charleston to San Juan?",
        "answer": "Since Puerto Rico is a U.S. territory, domestic ID rules apply: bring a Real ID or passport, and have a payment method for bags. No visa or passport validity requirements beyond standard U.S. domestic travel, but check if any health documents are needed for entry."

There are no capsule hotels or sleeping pods inside the terminals, but the Residence Inn offers spacious suites with full kitchens and a complimentary breakfast.",
