        "question": "What is the typical flight duration from Houston to San Salvador?",
        "answer": "A nonstop flight from Houston (IAH) to San Salvador (SAL) takes about 3 hours. With a layover, total travel time is typically 5 to 8 hours, depending on the connection. The return flight is similar in duration, though headwinds can add 15–30 minutes westbound. United and Avianca offer the fastest nonstop service."
      },
      "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 offer nonstop service: United runs up to 12 daily flights, Avianca has up to 6 daily flights, Volaris El Salvador (N3) flies on Tuesdays, Thursdays, and Saturdays, and Frontier operates on Mondays, Wednesdays, and Fridays. From HOU, the quickest one-stop options connect through DFW on American Airlines or through PTY/MIA on United/Avianca, with total travel times around 5 to 6 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 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 sufficient. Travelers of other nationalities should check El Salvador's visa policy, as many countries are visa-exempt while others require a visa obtained in advance. When returning to Houston, U.S. citizens only need a valid passport, while foreign nationals must meet U.S. entry requirements, which may include a visa or ESTA authorization."

      "q3": {
        "question": "What are the ground transportation options in San Salvador?",
        "answer": "San Salvador's main international airport, Monseñor Óscar Arnulfo Romero International Airport (SAL), is about forty kilometers from the city center. Taxis are the most common and reliable option, with authorized airport taxis offering fixed rates and a trip taking around forty-five minutes to an hour depending on traffic. Ride-share services like Uber operate in the area but may have limited availability at the airport due to local regulations, so you might need to walk slightly outside the terminal to meet the driver. Public buses run to the city but are not recommended for visitors because they are often crowded, slow, and pose safety concerns. Car rentals are available at the airport, but driving in San Salvador can be challenging due to heavy traffic and aggressive driving styles. Most travelers use authorized taxis for convenience and safety."

        "question": "When is the cheapest time to fly from Houston to San Salvador?",
        "answer": "Based on seasonal price data, 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 the Houston to San Salvador route, the best fares appear when booking 3 to 6 weeks in advance, with an average price around $511 during that window. Last-minute bookings tend to spike above $700, and while this data doesn't isolate summer or holiday periods, prices often rise further during those peak travel times, so booking earlier than the typical window is advisable.",
        "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.",

        "question": "Are overnight (red‑eye) flights available from Houston to San Salvador?",
        "answer": "There are no nonstop red‑eye flights from Houston (HOU) to San Salvador (SAL). A connecting itinerary exists with an overnight leg from Houston (IAH) to Mexico City (MEX) on United departing at 9:45 PM and arriving at 11:10 PM, followed by a long layover and a morning flight to San Salvador on Avianca, but no true late‑evening departure that arrives in San Salvador 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.",

      },
      "q13": {
        "question": "How do I get to William P Hobby Airport from the city center?",
        "answer": "From downtown Houston to Hobby Airport, METRO bus 40 takes about 50–60 min and is the cheapest. Rideshares and taxis take 20–30 min and are the most popular and convenient. Shuttles are available but less common. Driving and parking are options but cost more for long stays."

For connecting itineraries, common long-leg aircraft include the Boeing 737-800 and 737 MAX 9 via Dallas, Miami, or Panama City, as well as the Airbus A320 series.
