        "question": "What is the typical flight duration from Washington to San José?",
        "answer": "The flight from Washington Dulles to San José covers about 2,040 miles and typically takes 4 hours and 58 minutes outbound. The return leg is slightly shorter at 4 hours and 43 minutes, a modest difference driven by prevailing winds.",
        "methodology": "Carrier service, flight times and distances for this route come 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). We report the days of the week and the departure times each carrier operates. 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. Distance is the great-circle distance between the two specific airports named, so an actual flown track is typically 2-5% longer. Where shown, on-time departure and arrival rates and cancellation rates come from the U.S. Bureau of Transportation Statistics (BTS) Airline On-Time Performance dataset, which covers U.S. domestic routes only; where a typical fare is shown, it comes from the U.S. DOT Airline Origin and Destination Survey (DB1B), a quarterly 10% sample of tickets sold.",

Public buses run 24 hours to downtown San José with departures roughly every 10 minutes during the day from the airport bus stop. Ride‑share services like Uber operate in the area, though pickup points may be slightly away from the terminal exit. Car rental counters for major agencies are in the arrivals hall. Buses are the most‑used option for their low cost and frequency, while an official taxi is the fastest door‑to‑door choice.",

        "answer": "The cheapest months to fly from Washington to San José are September, October, and February, with average fares around $299–$319. The most expensive months are December, July, and June, with averages from $358 to $382.",
        "methodology": "This seasonal price baseline is a 365-day daily curve of typical round-trip fares for the route, precomputed monthly in-house from Priceline's own air booking-summary archive (the same data that backs the site), not a third party. For each calendar day we take a representative round-trip fare — a blend of the 25th-percentile and average ticket price over the route's bookings — and Gaussian-smooth the series so it reads as a clean seasonal trend rather than day-to-day noise. Thin and international routes are neighbor-filled: the seasonal shape is borrowed from the nearest dense routes (by origin-and-destination great-circle distance) with the price level anchored to the route's own bookings, so a sparse route still shows a plausible curve. It reflects current fares and is refreshed monthly.",

        "question": "How far in advance should I book tickets from Washington to San José?",
        "answer": "For flights from Washington (IAD) to San José (SJO), the optimal booking window is about 4–6 weeks before departure, averaging $323 round-trip. Booking around 30 days out typically yields the lowest fares at $322, while prices rise steadily if you book more than 10 weeks ahead, peaking near $451 at 160 days. For summer and holiday periods, you should book earlier — roughly 8–10 weeks out — since demand pushes fares higher and the cheapest inventory disappears sooner.",
        "methodology": "This booking-window guidance comes from the same monthly in-house analysis of Priceline's own air booking-summary archive. It expresses the typical round-trip fare as a function of how many days before departure a trip is booked — from about 180 days out down to the day of departure — aggregating the route's bookings by advance-purchase days and Gaussian-smoothing the curve the same way as the seasonal baseline. From that curve we highlight the stretch of lead times with the lowest average fare as the suggested booking window. Thin and international routes are neighbor-filled from the nearest dense routes, with the price level anchored to the route's own bookings. It reflects current fares and is refreshed monthly.",

        "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.",

      },
      "q12": {
        "question": "Which airport should I use in San José?",
        "answer": "San José has one main international airport, Juan Santamaría International Airport, located about 20 minutes northwest of downtown. It serves all major airlines flying to Costa Rica and is the only airport you will use."
      },
      "q13": {
        "question": "How do I get to Washington Intl Airport from the city center?",
        "answer": "From downtown Washington, D.C., the fastest and most popular option is the Silver Line Express bus to the Wiehle-Reston East Metrorail station, then the Silver Line train into the city — the bus runs every 15–20 minutes from Arrivals Door #4 and costs $5 each way, with Metrorail fare separate. Taxis and ride‑share services like Uber and Lyft are available 24/7 from the terminal, offering a direct but more expensive door‑to‑door trip. Shared‑van services such as SuperShuttle and Supreme Shuttle also serve the airport, and driving yourself is possible with economy parking at $15 per day plus a free shuttle to the terminal.",
