        "question": "What is the typical flight duration from Greenville to San Juan?",
        "answer": "There are no nonstop flights from Greenville (GSP) to San Juan (SJU). Most itineraries include one connection in a hub such as Charlotte, Atlanta, or Miami, with total travel times generally ranging from 5 to 7 hours, depending on the layover duration."
      },
      "q1": {
        "question": "Are there any direct flights from Greenville to San Juan?",
        "answer": "There are no nonstop flights from Greenville (GSP) to San Juan (SJU). The shortest connecting option is typically via Charlotte (CLT) on American Airlines, with a total travel time around 6½ to 7 hours including the layover. Other common one‑stop routings go through Miami, Chicago O'Hare, or Houston, but Charlotte offers the most frequent connections.",
        "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).

        "question": "Are there visa requirements to travel from Greenville to San Juan?",
        "answer": "No visa is required for this route because both Greenville, South Carolina, and San Juan, Puerto Rico, are within the United States. U.S. citizens and lawful permanent residents can travel freely between them without any visa or travel authorization. For foreign nationals already in the U.S., domestic travel between these cities does not require a visa, but they should carry valid identification and proof of legal status, as Puerto Rico is a U.S. territory and the same immigration rules apply."
      },
      "q3": {
        "question": "What are the ground transportation options in San Juan?",
        "answer": "From Luis Muñoz Marín International Airport (SJU), you can reach central San Juan—about 4 to 7 miles away—by taxi, rideshare (Uber is available), rental car, or public bus (AMA). Taxis and rideshares are the fastest and most convenient, taking 15–25 minutes depending on traffic. The AMA bus is the cheapest at $0.75 per ride, but service is less frequent and stops are more limited. Car rentals are widely available at the airport, though parking in Old San Juan can be challenging. Most visitors and locals rely on taxis or rideshares for the quickest and most reliable connection.",

        "question": "When is the cheapest time to fly from Greenville to San Juan?",
        "answer": "The cheapest months to fly from Greenville to San Juan are September, October, and August, with average fares as low as $489. The most expensive months are December, June, and July, where average prices climb above $700.",
        "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.",

      "q5": {
        "question": "How far in advance should I book tickets from Greenville to San Juan?",
        "answer": "For flights from Greenville to San Juan, the best fares typically appear when booking 19 to 22 weeks ahead, with an average price around $569. The absolute lowest price ($538) is available about 150 days before departure, while waiting until the last minute can cost up to $799. Summer and holiday periods may require booking slightly earlier within that window to avoid premium pricing.",
        "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.",

One connecting red‑eye itinerary exists: United via Houston (IAH), where the overnight leg IAH→SJU departs at 11:56 PM and arrives at 5:29 AM, landing in the early hours. The full trip includes a GSP→IAH flight on United with a layover of about 5 hours 11 minutes.",
        "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.",

        "question": "Which airlines usually operate this route from Greenville to San Juan?",
        "answer": "There are no nonstop flights from Greenville–Spartanburg to San Juan. American Airlines offers the most one‑stop options, connecting through Charlotte (about 8 daily departures) or Miami (about 6 daily). United connects via Chicago O'Hare, Houston, Newark, and Washington Dulles with a few daily patterns each, while Southwest links through Baltimore with a couple of daily flights. No per‑carrier fare data is available for this route.",

        "answer": "Common layover cities include Charlotte, Atlanta, and Miami. Charlotte and Atlanta offer many daily flights to San Juan with efficient connections, while Miami provides multiple options on American Airlines and other carriers. These hubs keep total travel time competitive."
      },
      "q9": {
        "question": "How reliable are on‑time departures on this route from Greenville to San Juan?",

        "question": "What documents should I bring with me to the airport when flying from Greenville to San Juan?",

      },
      "q12": {
        "question": "Which airport should I use in San Juan?",
        "answer": "San Juan has one main commercial airport, Luis Muñoz Marín International Airport, which serves all flights to the city."
      },
      "q13": {
        "question": "How do I get to Spartanburg Intl Airport from the city center?",
        "answer": "From downtown Greenville to GSP, driving or ride‑share is the most popular and fastest option, taking about 15–20 minutes via I‑85 with on‑airport parking available. Taxis and private shuttle services also serve the airport, while public transit is very limited and not a practical choice for most travelers. Ride‑share pickup and drop‑off is located directly at the terminal, making it the most convenient door‑to‑door option.",
