        "question": "What is the typical flight duration from Houston to San Salvador?",
        "answer": "A nonstop flight from Houston (IAH) to San Salvador (SAL) typically takes about 2 hours 50 minutes to 3 hours 10 minutes. With one stop, common layover cities like Miami or Panama City can extend total travel time to around 5 to 7 hours, depending on connection duration. The return flight from San Salvador to Houston is usually similar in duration, though headwinds may add a few minutes."
      },
      "q1": {
        "question": "Are there any direct flights from Houston to San Salvador?",
        "answer": "There are no nonstop flights from Houston Hobby (HOU) to San Salvador (SAL), but from Houston Bush Intercontinental (IAH) four airlines fly nonstop: United runs up to 80 flights a week (daily, with a median fare around $1,137), Avianca operates 36 weekly flights (daily, median ~$637), Volaris El Salvador flies on Tuesdays, Thursdays, and Saturdays (10 weekly), and Frontier runs three weekly on Mondays, Wednesdays, and Fridays (median ~$830).",
        "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). 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 Houston to San Salvador?",
        "answer": "Yes, visa requirements depend on your citizenship. U.S. citizens do not need a visa for tourism or business stays up to 90 days in El Salvador, but must purchase a tourist card on arrival. Salvadoran citizens require a visa to enter the U.S., unless they hold a valid U.S. visa or are eligible for the Visa Waiver Program (which currently excludes El Salvador). Other nationals should check both Salvadoran and U.S. entry rules based on their passport."
      },
      "q3": {
        "question": "What are the ground transportation options in San Salvador?",
        "answer": "El Salvador International Airport (SAL) is about 50 km from San Salvador, and taxis are the most common way to reach the city center, taking roughly 45 minutes. Official airport taxis and ride-sharing apps like Uber are available, with taxis generally being the fastest and most used option. There is no direct mass transit rail link, but some private shuttle services and car rentals are offered at the airport. For budget travelers, public buses run from the airport to the city, though they are slower and less convenient.",

        "question": "When is the cheapest time to fly from Houston to San Salvador?",
        "answer": "May, April, and September are the cheapest months to fly from Houston to San Salvador, with average fares around $403–$424. December is the most expensive month, averaging $792, followed by March and January at about $600.",
        "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 Houston to San Salvador?",
        "answer": "For flights from Houston to San Salvador, the best fares are typically found when booking 15 to 18 weeks ahead, with an average price around $536. The absolute cheapest single fare observed was $528 at 110 days out, while last-minute bookings can cost over $850.",
        "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.",

        "answer": "No nonstop red-eye flights operate from Houston (HOU) to San Salvador (SAL). One connecting itinerary exists whose long leg is an overnight flight: United's Houston Intercontinental (IAH) to Mexico City (MEX) leg departs at 9:45 PM and arrives at 11:10 PM the same night, connecting onward via Avianca through Mexico City with a layover of about 4 hours 50 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 Houston to San Salvador?",
        "answer": "There is no nonstop service from Houston Hobby to San Salvador. The most common one-stop routings are on United and Avianca, with United connecting through Mexico City (about 10 daily options) or San José, Costa Rica (7), and Avianca via Dallas/Fort Worth (6) or Miami (5). American also offers connections via Dallas/Fort Worth and Miami. Fares are not available for this route.",

        "answer": "Common layover cities include Miami, Panama City, and Mexico City, which offer efficient connections and competitive total travel times. Miami provides extensive onward flights to Central America. Panama City's hub is compact and easy to navigate. Mexico City offers multiple daily frequencies and visa‑free transit for many nationalities."
      },
      "q9": {
        "question": "How reliable are on‑time departures on this route from Houston to San Salvador?",
        "answer": "On‑time performance is generally reliable, though afternoon thunderstorms in Houston can cause delays. Early flights, particularly those operated by United or Avianca, tend to depart closer to schedule."

        "answer": "Bring a passport valid for at least six months, proof of onward or return travel, and a payment method for baggage. U.S. citizens do not need a visa for stays under 90 days, but check for any vaccination requirements."
      },
      "q12": {
        "question": "Which airport should I use in San Salvador?",

      },
      "q13": {
        "question": "How do I get to William P Hobby Airport from the city center?",
        "answer": "From downtown Houston to William P. Hobby Airport, ride‑share services like Uber and Lyft are the most popular and typically the fastest option, while taxis offer a similar door‑to‑door experience at a slightly higher cost. Shared shuttle vans and public buses provide lower‑cost alternatives, though they take longer. Driving yourself is also straightforward with ample on‑site parking, and reserving a spot online can save up to 50%.",
