        "question": "What is the typical flight duration from Houston to Liberia?",
        "answer": "A nonstop flight from Houston (IAH) to Liberia, Costa Rica (LIR) typically takes about 3 hours and 30 minutes.

United Airlines operates the fastest nonstop service on this route."

      "q1": {
        "question": "Are there any direct flights from Houston to Liberia?",
        "answer": "Yes, United Airlines flies non‑stop from Houston (IAH) to Liberia (LIR) daily, with multiple departures throughout the day ranging from early morning to late afternoon.",
        "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": "What are the ground transportation options in Liberia?",
        "answer": "From Liberia Airport (LIR), taxis and ride‑sharing are the primary ground transportation options for reaching the city center, about a fifteen‑minute drive. Official airport taxis are readily available and offer fixed rates, while Uber operates in Liberia but may have limited availability compared to taxis. There is no mass transit directly serving the airport, though public buses run along the main road a short walk away and offer a very cheap but infrequent option. Car rentals are popular for travelers continuing to beaches or national parks and are available at the airport. Most visitors heading into Liberia city center use taxis for their convenience and speed, as the distance is short and the fare is reasonable."

      "q4": {
        "question": "When is the cheapest time to fly from Houston to Liberia?",
        "answer": "Based on seasonal price data, the cheapest months to fly from Houston (IAH) to Liberia (LIR) are September, October, and November, with average fares around $547 to $611. The most expensive months are December, April, and March, with average fares climbing to $768 to $813.",
        "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 Liberia?",
        "answer": "For the Houston to Liberia route, the best fares typically appear when booking 19 to 22 weeks ahead, averaging around $650, with the absolute lowest price around $648 about 105 days before departure. During summer or holiday peaks, you'll want to book even earlier — at least 5 to 6 months out — as last-minute tickets can climb above $950.",
        "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.",

Connecting options exist where the overnight leg departs Los Angeles (LAX) around 11:46 PM on Alaska Airlines and arrives in Liberia around 6:37 AM, but these require an initial flight from Houston to LAX with a layover of roughly 1h50m.",
        "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.",
