        "question": "What is the typical flight duration from Charlotte to San Salvador?",

      },
      "q2": {
        "question": "Are there visa requirements to travel from Charlotte to San Salvador?",
        "answer": "Yes — visa requirements depend on your nationality. If you are a U.S. citizen traveling from Charlotte to San Salvador, you do not need a visa for tourism for stays up to 180 days; you must purchase a tourist card upon arrival for $12. If you are a Salvadoran citizen or resident, you may need a U.S. visa to enter the United States on the return, unless you hold a valid U.S. visa or are a U.S. citizen. Other nationalities should check both El Salvador and U.S. entry rules."
      },
      "q4": {
        "question": "When is the cheapest time to fly from Charlotte to San Salvador?",
        "answer": "The cheapest months to fly from Charlotte to San Salvador are February, September, and January, with average fares around $616–$639. The most expensive month is December, with an average fare of $944, and March and July are also pricey, averaging above $720.",
        "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 Charlotte to San Salvador?",
        "answer": "For flights from Charlotte to San Salvador, the best fares are typically found by booking 13 to 16 weeks ahead, with an average price around $612 and the absolute lowest around $602 at 95 days out. Last-minute bookings (under 3 weeks) can spike above $670, and while summer or holiday periods will push prices higher, aiming for that 3-4 month window still offers the best chance at a lower fare.",
        "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.",

      "q6": {
        "question": "Are overnight (red‑eye) flights available from Charlotte to San Salvador?",
        "answer": "No overnight (red-eye) flights operate on the CLT to SAL route — neither nonstop red-eyes nor connecting itineraries with a red-eye long leg are scheduled. All service on this route runs during daytime or earlier evening hours.",
        "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.",

      "q7": {
        "question": "Which airlines usually operate this route from Charlotte to San Salvador?",
        "answer": "There are no nonstop flights from Charlotte to San Salvador. The most common connecting routings are operated by Avianca via Washington Dulles (IAD) with about 10 daily options, and American Airlines via Miami (MIA) or Dallas/Fort Worth (DFW) with roughly 7 and 6 daily options, respectively. United also offers connections via IAD, Houston (IAH), and Newark (EWR), while Avianca connects via Toronto (YYZ) and Fort Lauderdale (FLL). Specific per-carrier fares are not available for this route.",
        "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.",

      },
      "q9": {
        "question": "How reliable are on‑time departures on this route from Charlotte to San Salvador?",
        "answer": "On‑time performance is generally reliable, though afternoon thunderstorms at Charlotte can cause delays. Early morning departures on American Airlines offer the best odds of punctuality."

      "q10": {
        "question": "Which months have the best weather for traveling to San Salvador?",

      },
      "q12": {
        "question": "Which airport should I use in San Salvador?",
        "answer": "San Salvador has one main airport, El Salvador International Airport (SAL), which serves all commercial flights and is located about 40 km southeast of downtown."
      },
      "q13": {
        "question": "How do I get to Douglas Intl Airport from the city center?",
        "answer": "From Uptown Charlotte, the most popular and affordable way to reach the airport is the CATS Sprinter bus, which offers direct service from the city center to the terminal. Ride-sharing services like Uber and Lyft are widely available and faster, with dedicated pickup zones at the airport, while taxis queue curbside on the arrivals level. Driving and parking is straightforward with several on-site lots and decks, though it is the most expensive option for longer trips.",
