        "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). A typical one-stop flight takes about 5 hours 30 minutes to 7 hours total travel time, depending on the connection. Common layover airports include Charlotte (CLT) and Atlanta (ATL). The return flight duration is similar, though sometimes slightly shorter due to tailwinds."

      "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 routings are typically via Charlotte (CLT) on American, with a total travel time around 5 hours 50 minutes, or via Miami (MIA) also on American at roughly 6 hours 50 minutes. Other one-stop options include connections through Baltimore (BWI) on Southwest, or through Washington Dulles (IAD), Chicago O'Hare (ORD), Houston (IAH), or Newark (EWR) on United, with total times ranging from about 6 to 8 hours.",
        "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": "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 can travel freely between the mainland and Puerto Rico with just a valid government-issued photo ID. For non-U.S. citizens, the same U.S. immigration rules apply as for any domestic U.S. travel, so no additional visa is needed beyond what is required to be in the United States."

      "q3": {
        "question": "What are the ground transportation options in San Juan?",
        "answer": "From Luis Muñoz Marín International Airport (SJU) to San Juan’s city center, taxis are the most used and convenient option, with fixed rates to areas like Old San Juan and Condado taking about fifteen to twenty minutes. Ride-share services such as Uber and Lyft are available but may have slightly longer wait times and limited pickup zones. Public buses, operated by AMA, are the most affordable but are slow and unreliable, with routes T5 and D53 serving the airport. The Tren Urbano light rail does not directly connect to the airport. Car rentals are widely available at the airport and useful for exploring beyond the city, though parking in Old San Juan is difficult. Shared shuttle vans also operate to major hotels. Most travelers opt for taxis due to their availability and simplicity."

        "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 $513–$531, while the most expensive months are June, December, and March, where average fares range from $660 to $699.",
        "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 Greenville to San Juan?",
        "answer": "For the best fare on flights from Greenville to San Juan, aim to book 20 to 23 weeks in advance, when prices average around $553; the absolute cheapest single ticket found was $506 at about 180 days (roughly 26 weeks) out. During peak summer or holiday periods, demand can shift the ideal window earlier, so booking 25–30 weeks ahead is safer to avoid last‑minute spikes up to $778.",
        "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.",

A connecting overnight option exists via Houston (IAH) on United, where the long leg IAH→SJU departs around 11:56 PM and arrives at 5:29 AM, but no direct late-evening departure from GSP itself is available.",
        "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.",

The airport is a hub for airlines like JetBlue and serves major U.S. carriers, offering connections throughout the Caribbean and the mainland U.S. There are no other commercial airports in the immediate San Juan area, so SJU is the only practical choice."
