        "question": "Which cities in Costa Rica can I fly to from Denver?",
        "answer": "From Denver you can fly non-stop to Liberia in the northwest, good for Pacific beaches. One-stop routes via Houston, Dallas or Miami reach San José, the capital and gateway to the central valley and Caribbean coast."
      },
      "q1": {
        "question": "How long is the flight from Denver to Costa Rica?",
        "answer": "From Denver to Costa Rica, non-stop flights to Liberia, Guanacaste typically take around 5 hours, while one-stop routes to San José usually range from 6 to 8 hours. Westbound returns are often slightly longer due to headwinds, typically adding 30 minutes to an hour."
      },
      "q2": {
        "question": "Are there direct flights from Denver to Costa Rica?",

In low season or on other carriers, one-stop connections via Houston, Dallas, or Atlanta are common, with total travel times of roughly 7 to 9 hours."

      "q4": {
        "question": "When is the cheapest time to fly from Denver to Costa Rica?",
        "answer": "The cheapest months to fly from Denver to Costa Rica are typically May, April, and June, when fares dip well below the December and March peaks. Booking about 11 to 14 weeks ahead tends to land the best price, and departing on a Tuesday or during the late-night or evening window often saves money compared to pricier Saturday or Thursday flights. Peak summer and major holidays like Christmas usually push fares noticeably higher.",
        "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. 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. The cheapest day of the week and time of day to depart are drawn from the same large sample of real fares Priceline users found on this route in the last 72 hours, grouped by the day of the week and by the time-of-day window of the outbound departure, with the lowest and average price reported for each."

        "question": "How far in advance should I book flights from Denver to Costa Rica?",
        "answer": "For flights from Denver to Costa Rica, the best booking window is about 11 to 14 weeks before departure, when average fares hover around $531.",

        "question": "What are the most popular cities to visit in Costa Rica?",
        "answer": "In Costa Rica, most visitors head to San José for culture and as a transit hub, then to Arenal for volcanoes and hot springs, Manuel Antonio for beaches and wildlife, and Monteverde for cloud forests."
      },
      "q8": {
        "question": "Which airports in Costa Rica are best to fly into from Denver?",
        "answer": "From Denver to Costa Rica, Juan Santamaría International Airport in San José offers the most long-haul options and is the main hub for connecting flights or road transfers to both Pacific and Caribbean coasts. Liberia Guanacaste Airport is a better choice if you are headed directly to northwest beach resorts, with shorter transfer times to popular areas like Tamarindo and Papagayo. There is no rail network for onward travel, so most visitors rely on rental cars, shuttles or domestic flights."

      "q12": {
        "question": "When is the best time of year to visit Costa Rica?",
        "answer": "For Costa Rica, December to April is the dry season with sunny days but higher prices and crowds. May to November is the green season, with rain mostly in the afternoons, lower rates, and lush landscapes."
      },
      "q13": {
        "question": "How do I get to Denver Intl Airport from the city center?",
        "answer": "The A Line commuter train is the most popular and fastest way to get from downtown Denver to Denver International Airport, taking about 37 minutes from Denver Union Station. Public buses, including RTD regional routes, also serve the airport from various points in the metro area. Ride‑share services like Uber and Lyft, as well as taxis, offer door‑to‑terminal convenience at a higher cost. Driving and parking at the airport is straightforward, with multiple on‑site lots and economy options, but it's typically the most expensive choice for longer trips.",
