        "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 25 minutes to 5 hours 45 minutes. With one stop, common layovers include Houston or Dallas, bringing total travel time to roughly 7 to 9 hours. Return flights from San José to Denver often take slightly longer, around 5 hours 45 minutes to 6 hours nonstop, due to prevailing winds."
      },
      "q1": {
        "question": "Are there any direct flights from Denver to San José?",
        "answer": "Yes, there are nonstop flights from Denver (DEN) to San José (SJO). United Airlines flies daily with two daily departures around 3:48 PM and 3:55 PM, while Southwest operates four weekly flights on Saturdays and Sundays with departures at 7:00 AM, 8:55 AM, 1:55 PM, and 2:30 PM.",
        "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 San José?",
        "answer": "Juan Santamaría International Airport (SJO) is about 20 kilometers from downtown San José. Official orange taxis are available directly outside the terminal, taking roughly 20 to 40 minutes to the city center depending on traffic, and are a safe and popular choice. Ride-share services like Uber and DiDi operate but face legal uncertainty, so pickup may be less straightforward. Public buses run regularly and are the cheapest option, though they take 30 to 60 minutes and can be crowded with limited luggage space. Car rentals are available but driving in San José is challenging due to congestion and aggressive drivers. Shared shuttles offer a good balance of cost and comfort. Most travelers use official taxis for their convenience and reliability."
      },
      "q4": {
        "question": "When is the cheapest time to fly from Denver to San José?",
        "answer": "Based on seasonal price data for Denver to San José, the cheapest months to fly are April (average $471), May ($480), March ($502), and September ($546), while December is the most expensive at an average of $776, followed by January ($615) and February ($598).",
        "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 Denver to San José?",
        "answer": "For the Denver to San José route, the best fares are typically found when booking 11 to 14 weeks in advance, averaging around $515. Booking very last-minute (0 days out) can sometimes yield a slightly lower fare of $495, but prices rise sharply during peak summer and holiday periods, so aiming for that 3-to-4-month window is generally safest.",
        "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 Denver (DEN) to San José (SJO). Connecting overnight options exist — for example, Copa Airlines via Panama City with the long leg DEN→PTY departing around 10:42 PM and arriving at 5:32 AM, or United via San Francisco with the SFO→SJO leg departing around 11:36 PM and arriving at 7:15 AM — but no direct late-evening nonstop service.",
        "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.",

United operates about 9 weekly flights, while Southwest runs 4 weekly flights on weekends. Other carriers may serve this route with connections, but the schedule data shows United and Southwest as the nonstop operators.",
