        "question": "What is the typical flight duration from Liberia to Houston?",
        "answer": "A nonstop flight from Liberia (LIR) to Houston (IAH) typically takes about 3 hours 30 minutes to 3 hours 45 minutes, with United Airlines offering direct service. One-stop flights, often connecting through San Salvador or Miami, range from 6 to 9 hours total travel time. The return flight from Houston to Liberia is usually a bit longer, averaging 3 hours 45 minutes to 4 hours nonstop due to prevailing winds."
      },
      "q1": {
        "question": "Are there any direct flights from Liberia to Houston?",
        "answer": "Yes, United Airlines flies nonstop from Liberia (LIR) to Houston (IAH) daily, with up to seven departures spread across the day from early morning through late afternoon. It is the only airline offering nonstop service on 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. 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 Liberia to Houston?",
        "answer": "Yes, visa requirements apply for travel from Liberia, Costa Rica (LIR) to Houston, Texas (IAH). U.S. citizens do not need a visa to enter the U.S., but all other travelers must comply with U.S. entry rules. Costa Rican citizens generally need a visa to enter the U.S., unless they hold a valid U.S. visa or are eligible for the Visa Waiver Program (Costa Rica is not a VWP country). Travelers should check their specific nationality requirements on the U.S. Department of State website. Additionally, all Visa Waiver Program travelers must have an approved ESTA. For the return trip, U.S. citizens can enter Costa Rica without a visa for stays up to 90 days."

        "question": "What are the ground transportation options in Houston?",
        "answer": "From George Bush Intercontinental Airport (IAH) to downtown Houston, taxis, ride‑share services like Uber and Lyft, rental cars, and a limited mass‑transit bus are available. METRO bus route 102 runs to the city center but takes about sixty to ninety minutes and is infrequent, making it the least used option. Taxis and ride shares take twenty‑five to forty‑five minutes depending on traffic and are the most popular choices for visitors without a car. Rental cars are widely available and convenient given Houston’s sprawling layout and limited public transit, but parking downtown can be expensive. There is no direct rail link from IAH. Most travelers prefer ride‑share services for a balance of cost and convenience, while business travelers often use taxis or rentals."

        "question": "When is the cheapest time to fly from Liberia to Houston?",
        "answer": "The cheapest months to fly from Liberia to Houston are September (average $547), October ($579), and November ($611), while the most expensive are December (average $813), April ($784), and March ($768).",
        "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. For this route, fares for the requested travel direction were unavailable, so the pattern shown is derived from the reverse direction, which shares the same seasonal demand cycle.",

        "question": "How far in advance should I book tickets from Liberia to Houston?",
        "answer": "For flights from Liberia, Costa Rica to Houston, the best fares are typically found when booking 19 to 22 weeks ahead, with an average price around $650. Booking about 105 days (15 weeks) before departure can also yield a low price near $648, but last-minute purchases can spike to $977 or more.",
        "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. For this route, fares for the requested travel direction were unavailable, so the pattern shown is derived from the reverse direction, which shares the same seasonal demand cycle.",

        "answer": "No red‑eye (overnight) flights are available from Liberia, Costa Rica (LIR) to Houston (IAH) — the schedule data shows no nonstop red‑eyes on this route, and no connecting itineraries with an overnight long leg were found.",
        "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 Guanacaste Airport from the city center?",
