        "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 55 minutes to 3 hours 5 minutes. With one stop, depending on the connection city, total travel time often ranges from 5 to 8 hours."
      },
      "q1": {
        "question": "Are there any direct flights from Houston to San Salvador?",
        "answer": "Yes, nonstop flights from Houston (IAH) to San Salvador (SAL) are available on United, Avianca, Volaris El Salvador, and Frontier. United operates about 80 weekly flights daily, Avianca runs roughly 36 weekly flights also daily, Volaris El Salvador flies about 10 weekly on Tuesdays, Thursdays, and Saturdays, and Frontier offers 3 weekly on Mondays, Wednesdays, and Fridays. Typical fares are around $637 on Avianca, $830 on Frontier, and $1,137 on United.",
        "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.",

        "question": "Are there visa requirements to travel from Houston to San Salvador?",
        "answer": "Yes, there are requirements. For travel from Houston to San Salvador, U.S. citizens do not need a visa for visits up to 90 days. Salvadoran nationals can enter El Salvador with just a valid Salvadoran passport. For the return trip, Salvadoran nationals require a U.S. visa or ESTA under the Visa Waiver Program, while U.S. citizens can re-enter with a valid U.S. passport."

      "q3": {
        "question": "What are the ground transportation options in San Salvador?",
        "answer": "From El Salvador International Airport (SAL) to San Salvador, taxis are the most common and reliable option, with fixed rates to the city center around $30–35 and a ride of about 45 minutes. Ride‑sharing services like Uber operate but are less universally available and may face restrictions directly at the terminal. Car rentals are available from major agencies, though driving in the city can be challenging for visitors. There is no train or dedicated mass‑transit link from the airport, and public buses exist but are not recommended for tourists due to safety and comfort concerns. Taxis remain the most‑used choice for a straightforward, secure transfer.",

        "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 May, April, and September, with average fares around $403, $413, and $424 respectively. The most expensive months are December, March, and January, with December spiking to an average of $792.",
        "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 optimal booking window is roughly 15 to 18 weeks before departure, with average fares around $536 and the single cheapest day at about 110 days out. Prices start climbing sharply inside 4 weeks, so for summer or holiday travel it's even more important to book within that 3-4 month window to avoid last-minute spikes.",
        "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 operates a daily nonstop red-eye from Houston (IAH) to San Salvador (SAL), departing at 9:39 PM. The flight arrives the same night — not the next morning — given the short flight time on this route.",
        "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.",

Avianca runs about 36 weekly flights at a median fare near $637, while Volaris El Salvador offers 10 weekly flights on Tuesdays, Thursdays, and Saturdays. Frontier flies 3 times a week on Mondays, Wednesdays, and Fridays, with a median fare around $830.",

      "q12": {
        "question": "Which airport should I use in San Salvador?",
        "answer": "San Salvador has only one airport, El Salvador International Airport, also known as Monseñor Óscar Arnulfo Romero International Airport. It is located about 40 kilometers southeast of downtown San Salvador."
      },
      "q13": {
        "question": "How do I get to George Bush Intercontinental Airport from the city center?",
        "answer": "From downtown Houston, you can reach George Bush Intercontinental Airport (IAH) via the METRO 102 Bush IAH Express bus, ride‑share services like Uber and Lyft, taxis, or by driving and parking on‑site. Ride‑share and taxis are the most popular and offer door‑to‑door convenience in about 25–40 minutes depending on traffic, while the bus is the most budget‑friendly option. Driving yourself is also common, with various parking choices from economy lots to reserved garage spaces. The Hardy Toll Road provides a direct expressway connection from the city center.",

        "question": "Which airline alliances serve flights from Houston to San Salvador?",
        "answer": "Star Alliance is the only global alliance with nonstop service from Houston to San Salvador, represented by United and Avianca. Volaris El Salvador (N3) and Frontier also fly the route but belong to no alliance. Other alliances may serve it via connections, but no Oneworld or SkyTeam carriers operate nonstop here.",
        "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.",
