        "question": "What is the typical flight duration from Greenville to San Juan?",
        "answer": "There are no scheduled nonstop flights from Greenville, South Carolina (GSP) to San Juan, Puerto Rico (SJU), so the route requires a connection, typically taking around 5 to 7 hours total travel time depending on layover. The distance between the airports is about 1,510 miles.",
        "methodology": "Carrier service, flight times and distances for this route come 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). We report the days of the week and the departure times each carrier operates. The typical flight time is the median scheduled block time, given both per carrier and across all carriers on the route; where a schedule does not publish an elapsed time, it is derived from the scheduled departure and arrival times converted to UTC. Outbound and return times are computed by the same method, so the difference between them is directly comparable and reflects prevailing winds rather than any change in derivation. Distance is the great-circle distance between the two specific airports named, so an actual flown track is typically 2-5% longer. Where shown, on-time departure and arrival rates and cancellation rates come from the U.S. Bureau of Transportation Statistics (BTS) Airline On-Time Performance dataset, which covers U.S. domestic routes only; where a typical fare is shown, it comes from the U.S. DOT Airline Origin and Destination Survey (DB1B), a quarterly 10% sample of tickets sold.",

The quickest one‑stop itineraries connect through Charlotte (CLT) on American, with the longer leg on an A321 taking about 73 minutes and the short leg about 223 minutes, plus a layover of around 104 minutes — total travel time roughly 6½ to 7 hours. Other common connections go through Miami, Newark, or Houston, though Charlotte offers the most frequent options.",

        "answer": "From Luis Muñoz Marín International Airport (SJU), taxis and ride-shares like Uber are readily available and offer the fastest door-to-door trip to the city center, with fixed-rate taxis to areas like Old San Juan, Condado, and Isla Verde. Public buses operated by the AMA serve the airport via routes like the E40, but service can be infrequent and requires exact change or a transit card; it’s the cheapest option at $0.75 but not the most practical for visitors with luggage. Car rentals from major agencies are available on-site, though navigating San Juan’s traffic and limited parking can be challenging. Most visitors opt for taxis or ride-shares for their convenience and speed.",

        "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 October, February, and January, with average fares around $448, $450, and $452 respectively. The most expensive months are December, June, and July, with average fares reaching $544, $531, and $523. Low season (October, February, January, September) offers the best prices, while high season (March, July, June, December) sees the highest fares.",
        "methodology": "This seasonal price baseline is a 365-day daily curve of typical round-trip fares for the route, precomputed monthly in-house from Priceline's own air booking-summary archive (the same data that backs the site), not a third party. For each calendar day we take a representative round-trip fare — a blend of the 25th-percentile and average ticket price over the route's bookings — and Gaussian-smooth the series so it reads as a clean seasonal trend rather than day-to-day noise. Thin and international routes are neighbor-filled: the seasonal shape is borrowed from the nearest dense routes (by origin-and-destination great-circle distance) with the price level anchored to the route's own bookings, so a sparse route still shows a plausible curve. It reflects current fares and is refreshed monthly.",

        "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 are found when booking roughly 4 to 7 weeks before departure, with an average price around $412 in that window. The absolute cheapest single day to book is about 35 days out at $408, while booking very early (around 180 days) or at the last minute pushes prices toward $670 or more. Booking during that 4-7 week sweet spot tends to hold for most travel periods, though summer and holiday dates often require a bit more lead time to avoid peak pricing.",
        "methodology": "This booking-window guidance comes from the same monthly in-house analysis of Priceline's own air booking-summary archive. It expresses the typical round-trip fare as a function of how many days before departure a trip is booked — from about 180 days out down to the day of departure — aggregating the route's bookings by advance-purchase days and Gaussian-smoothing the curve the same way as the seasonal baseline. From that curve we highlight the stretch of lead times with the lowest average fare as the suggested booking window. Thin and international routes are neighbor-filled from the nearest dense routes, with the price level anchored to the route's own bookings. It reflects current fares and is refreshed monthly.",

        "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.",

United also offers one-stop options, primarily through Houston, Chicago O'Hare, or Newark, though less frequently. Southwest connects via Baltimore a couple of times a day.

Miami serves as a gateway with numerous Caribbean connections and streamlined transfers for Puerto Rico-bound passengers."

        "question": "Which months have the best weather for traveling to San Juan?",

      },
      "q11": {
        "question": "What documents should I bring with me to the airport when flying from Greenville to San Juan?",
        "answer": "Since Puerto Rico is a U.S. territory, travel from Greenville is domestic. Bring a Real ID-compliant driver’s license or passport, a payment method for any baggage fees, and check if any health documents are currently required."

      },
      "q13": {
        "question": "How do I get to Spartanburg Intl Airport from the city center?",
        "answer": "There is no public bus or train service directly to Greenville-Spartanburg International Airport, so the most popular options are ride-share services like Uber and Lyft, taxis, or driving yourself and parking in one of the on-site lots. Ride-share and taxis offer the quickest door-to-door trip from downtown Greenville or Spartanburg, typically taking 15–25 minutes depending on traffic, while driving and parking is convenient and often the most cost-effective if you're leaving a car for several days. Shuttle services are also available through private companies like Eastside Transportation, which can be booked in advance for group or executive travel. Overall, ride-share tends to be the fastest and most popular choice for solo travelers or couples, while parking is better for longer trips.",
