        "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. Flights with one stop, commonly in San Salvador (SAL) or Panama City (PTY), usually increase total travel time to between 5 and 7 hours. The return flight from Liberia to Houston is often slightly longer, averaging around 3 hours and 45 minutes nonstop."
      },
      "q1": {
        "question": "Are there any direct flights from Houston to Liberia?",
        "answer": "Yes, United flies nonstop from Houston (IAH) to Liberia, Costa Rica (LIR) daily, with about 43 flights a week and multiple departure times throughout the day — typically ranging from early morning to late afternoon. United is the only airline operating this route nonstop.",
        "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. 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 Liberia?",
        "answer": "Yes, visa requirements apply for travel from Houston to Liberia, Costa Rica, depending on nationality. U.S. citizens do not need a visa for stays up to 90 days but must have a valid passport and proof of onward travel. Costa Rican citizens need a valid U.S. visa or ESTA authorization to enter the United States. Travelers of other nationalities should check both Costa Rican entry requirements and U.S. re-entry rules, as they vary."
      },
      "q3": {
        "question": "What are the ground transportation options in Liberia?",
        "answer": "From Liberia Airport (LIR), the most practical way to reach the city center is by taxi or pre-arranged shuttle, as there is no public bus service directly at the terminal and ride-share apps like Uber are not reliably available. Official orange airport taxis are metered and the most used option, offering a fixed-fare trip to Liberia in about 15–20 minutes. Car rentals are available on-site from major agencies, giving flexibility for exploring the region, though driving in Costa Rica can be challenging due to road conditions. For budget travelers, public buses do pass along the main road about a 10-minute walk from the terminal, but this is less convenient with luggage. Private transfer services and hotel shuttles are also common, providing a comfortable middle ground.",

        "question": "When is the cheapest time to fly from Houston to Liberia?",
        "answer": "The cheapest months to fly from Houston to Liberia are October and September, with average fares around $565–$567, while December and July are the most expensive, averaging $813 and $802 respectively.",
        "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 Liberia?",
        "answer": "For flights from Houston to Liberia, the optimal booking window is roughly 12 to 15 weeks before departure, where fares average around $650. Booking last-minute can be significantly more expensive, with prices climbing above $900, while booking more than 15 weeks out yields only slight savings. During peak summer or holiday periods, it's wise to book at least 15 weeks ahead, as fares tend to rise closer to departure.",
        "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": "There are no nonstop red-eye flights from Houston (IAH) to Liberia (LIR), but connecting red-eye itineraries are available. The overnight leg operates from Los Angeles (LAX) to Liberia on Alaska Airlines (AS), departing at 11:46 PM and arriving at 6:37 AM — a next-morning arrival. You would connect in Los Angeles from a United or American flight with a layover of about 1 hour 45–55 minutes.",
        "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.",

San Salvador and Panama City offer efficient connections and visa-free transit for many nationalities, while Miami and Atlanta provide broad network options and frequent service, keeping overall travel time competitive."
      },
      "q9": {
        "question": "How reliable are on‑time departures on this route from Houston to Liberia?",
        "answer": "On-time performance is generally consistent, but afternoon thunderstorms in Houston can cause delays. Morning flights, particularly on United, tend to depart as scheduled."
      },
      "q10": {
        "question": "Which months have the best weather for traveling to Liberia?",

        "answer": "Bring a passport valid for at least six months, proof of onward or return travel, a payment method for bags, and any required health documents such as a yellow fever certificate if applicable. U.S. citizens do not need a visa for Costa Rica for stays under 180 days."
      },
      "q12": {
        "question": "Which airport should I use in Liberia?",

      "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) by taxi, ride‑share (Uber/Lyft), shared shuttle, or rental car; the most popular and fastest option is a ride‑share or taxi, which takes about 25–35 minutes in light traffic. Public transit via the METRO 102 Bush IAH Express bus runs from the downtown area to the airport and is the most budget‑friendly choice, though it takes longer. Driving yourself and parking at the airport is also possible, with economy lots being the cheapest on‑site option and advance booking offering discounts.",

On connecting itineraries, the long-haul leg is also typically a 737 variant — MAX 9 via Los Angeles, 737-800 via Dallas/Fort Worth or Miami, or MAX 8 via Denver — paired with regional jets or narrowbodies like the Embraer 175 or Airbus A320 family on the shorter leg.
