        "question": "What is the typical flight duration from Denver to San José?",
        "answer": "A nonstop flight from Denver (DEN) to San José (SJO) typically takes about 5 hours 30 minutes to 6 hours. With one stop, common layover cities like Houston or Miami bring the total travel time to around 7 to 9 hours. The return flight is often slightly shorter, usually around 5 hours 15 minutes to 5 hours 45 minutes nonstop."
      },
      "q1": {
        "question": "Are there any direct flights from Denver to San José?",
        "answer": "Yes, United and Southwest both fly nonstop from Denver to San José. United runs daily with two departures in the mid-afternoon, while Southwest flies four times a week — Saturdays and Sundays only — with morning and early-afternoon departures. Together they offer up to 13 weekly nonstop flights.",
        "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.",

      "q2": {
        "question": "Are there visa requirements to travel from Denver to San José?",
        "answer": "Yes, there are visa requirements depending on nationality. U.S. citizens do not need a visa for tourist stays up to 90 days in Costa Rica. Costa Rican citizens must have a valid U.S. visa or ESTA authorization to enter the United States. Travelers of other nationalities should check Costa Rican and U.S. entry requirements based on their citizenship."
      },
      "q4": {
        "question": "When is the cheapest time to fly from Denver to San José?",
        "answer": "The cheapest time to fly from Denver to San José is late spring and early summer, particularly May and April, when average fares drop to around $477–$496, while the most expensive period is December, with average fares reaching $755.",
        "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 Denver to San José?",
        "answer": "For the Denver to San José route, the sweet spot for the best fares is typically 11 to 14 weeks before departure, with an average price around $529. Booking very last-minute can sometimes yield a slightly lower fare, but for summer and holiday periods, you'll want to book even earlier—ideally 3 to 4 months out—to avoid steep price hikes.",
        "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": "No overnight (red-eye) flights are scheduled from Denver to San José, Costa Rica — neither nonstop nor connecting itineraries with a red-eye long leg turned up in the schedule data.",
        "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.",

        "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).

        "answer": "Common layover hubs include Houston (IAH), Dallas/Fort Worth (DFW), Miami (MIA), and Panama City (PTY). Houston and Dallas offer extensive domestic connections and efficient transfers for a smooth journey. Miami provides a quick, direct routing southward. Panama City’s Tocumen Airport is a major Latin American gateway with visa‑free transit for many nationalities, often yielding competitive total travel times."
      },
      "q9": {
        "question": "How reliable are on‑time departures on this route from Denver to San José?",
        "answer": "On‑time performance is generally good, though afternoon thunderstorms in Denver can cause delays. Early flights, particularly on United and Southwest, tend to depart more reliably."

        "question": "Which airport should I use in San José?",
        "answer": "San José has one main airport, Juan Santamaría International Airport, located about 20 minutes northwest of downtown and serving as the primary gateway for international and domestic flights."
      },
      "q13": {
        "question": "How do I get to Denver Intl Airport from the city center?",
        "answer": "From downtown Denver, the A Line commuter train offers a direct 37-minute ride to the airport, which is the fastest and most popular option. RTD buses also serve DEN, while ride‑share, taxis, and shuttles provide door‑to‑door convenience at a higher cost. Driving takes about 30‑40 minutes with parking available on‑site, though fees apply.",
