The typical flight time is the median scheduled block time, given both per carrier and across all carriers on the route; where a schedule does not publish an elapsed time, it is derived from the scheduled departure and arrival times converted to UTC. Outbound and return times are computed by the same method, so the difference between them is directly comparable and reflects prevailing winds rather than any change in derivation.

Ride‑share services like Uber operate in the area but may face restrictions, so taxis are generally faster and more predictable. Several car rental agencies have desks at the airport, giving you flexibility for onward travel.

The most expensive months are July, December, and August, when average prices climb above $799, peaking in July at $817.", "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.", "toolsUsed": ["seasonal_prices"]}, "q5": {"question": "How far in advance should I book tickets from Houston to Liberia?", "answer": "For flights from Houston to Liberia, Costa Rica, the best fares are typically found when booking 12 to 15 weeks ahead, with an average price around $650. The sweet spot is about 105 days out, where fares can dip to roughly $647, while last-minute bookings can exceed $980. During peak summer or holiday periods, demand pushes prices higher, so aiming for the earlier end of that window—around 15 weeks—is wise.", "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.", "toolsUsed": ["booking_timing"]}, "q6": {"question": "Are overnight (red‑eye) flights available from Houston to Liberia?", "answer": "No overnight / red‑eye flights are scheduled from Houston (IAH) to Liberia, Costa Rica (LIR) — neither nonstop nor connecting itineraries with a red‑eye long leg operate 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.", "toolsUsed": ["redeye_flights"]}, "q7": {"question": "Which airlines usually operate this route from Houston to Liberia?", "answer": "United Airlines operates nonstop service from Houston to Liberia, Costa Rica, with 43 weekly flights departing daily at various times throughout the day.
