        "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. The return nonstop flight is often slightly longer, around 3 hours to 3 hours 10 minutes, due to prevailing winds. With a layover, total travel time commonly ranges from 5 to 8 hours, depending on the connection point."
      },
      "q1": {
        "question": "Are there any direct flights from Houston to San Salvador?",
        "answer": "Yes, there are nonstop flights from Houston (IAH) to San Salvador (SAL). United Airlines and Avianca both fly the route daily, while Volaris El Salvador (N3) operates on Tuesdays, Thursdays, and Saturdays, and Frontier flies on Mondays, Wednesdays, and Fridays — so in total you have at least two airlines offering daily nonstops plus additional options several days a week.",
        "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.",

        "question": "Are there visa requirements to travel from Houston to San Salvador?",
        "answer": "Yes, there are visa requirements for travel from Houston to San Salvador depending on your nationality. U.S. citizens do not need a visa for tourism or business visits up to 90 days; a valid passport is required, and a tourist card purchased on arrival. Citizens of El Salvador also do not need a visa. Nationals of many other countries may require a visa; check with the nearest Salvadoran consulate. For the return flight from San Salvador to Houston, U.S. citizens only need a valid passport, while Salvadoran citizens and others may need a U.S. visa or ESTA if eligible under the Visa Waiver Program."

      "q3": {
        "question": "What are the ground transportation options in San Salvador?",
        "answer": "From El Salvador International Airport (SAL), also known as Comalapa, the most common way to reach San Salvador is by taxi or ride-share, taking about forty to fifty minutes. Official airport taxis are available at fixed rates and are considered safe and reliable, while Uber operates in the city and can be requested from the airport. Public buses run from the airport entrance to downtown but are not recommended for tourists due to safety concerns and limited comfort. Car rentals are available but driving in San Salvador can be challenging for visitors. There is no mass transit rail connection. Most travelers use official taxis or ride-share services for convenience and security."

        "question": "When is the cheapest time to fly from Houston to San Salvador?",
        "answer": "The cheapest months to fly from Houston to San Salvador are April (average $369), September ($379), and May ($403), while the most expensive are December (average $773), November ($538), and January ($528).",
        "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 Houston to San Salvador?",
        "answer": "For flights from Houston to San Salvador, the optimal booking window is about 3 to 6 weeks ahead, with average fares around $511 and the cheapest single fare at $506 around 30 days out. Booking last-minute (0 days) can spike to $778, while prices stay relatively flat between 15 and 55 days, so booking a bit earlier for summer or holiday travel is safer to avoid any late surges.",
        "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": "Yes, United Airlines operates a daily nonstop red‑eye from Houston (IAH) to San Salvador (SAL), departing around 9:39 PM and arriving the next morning.",
        "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.",

Panama City's Tocumen Airport is a major hub with efficient transfers and visa-free transit for many nationalities.

        "question": "How do I get to George Bush Intercontinental Airport from the city center?",
        "answer": "Public transit from downtown Houston to IAH is limited to the METRO 102 bus, which takes about 50–70 min and is the cheapest option. Most travelers use rideshare or taxis, which take 25–35 min and cost more. Shuttle services are available, and driving with on‑site parking is convenient but priciest."
