        "question": "What is the typical flight duration from Charlotte to San Juan?",
        "answer": "The flight from Charlotte to San Juan covers about 1,480 miles. Nonstop flights typically take 3 hours and 40 minutes, while the return leg is about 3 hours and 57 minutes, making the trip back slightly longer. One-stop itineraries generally add two to four hours of total travel time.",
        "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.",

        "question": "What are the ground transportation options in San Juan?",
        "answer": "From San Juan's Luis Muñoz Marín International Airport (SJU), taxis, ride-shares like Uber, and rental cars are the most practical options for reaching the city center, as the airport is just 4 to 7 miles east of San Juan's key districts. Public buses operated by the AMA serve the area but are less convenient for visitors due to limited routes and a requirement for exact change. Taxis offer fixed-rate fares to zones like Old San Juan and Condado, making them a popular and reliable choice. Ride-sharing services are widely available and often provide a comparable or lower cost than taxis, while rental cars are abundant for those planning to explore beyond the metro area. The fastest and most-used option is typically a taxi or ride-share, with the trip to Old San Juan taking about 15 minutes.",

        "question": "When is the cheapest time to fly from Charlotte to San Juan?",
        "answer": "The cheapest months to fly from Charlotte to San Juan are October, February, and January, with average fares around $370, $373, and $374 respectively; September is also relatively affordable at $382. The most expensive months are December at $464, March at $434, and June at $429, with May and July also in the higher range.",
        "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 Charlotte to San Juan?",
        "answer": "For flights from Charlotte to San Juan, the best time to book is roughly 4 to 6 weeks before departure, when fares average around $299. The single cheapest day to book is about 35 days out at $297, while booking 6 months ahead can cost as much as $507. For summer and holiday travel, you'll want to book earlier than the 4-6 week window, as those peak periods typically see higher demand and fares.",
        "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.",

Connecting itineraries with an overnight leg exist — for example, Frontier offers a red-eye from Philadelphia (PHL) to San Juan departing at 10:59 PM and arriving at 2:59 AM (early hours), and another from Orlando (MCO) departing at 11:17 PM and arriving at 2:15 AM (early hours), both requiring a connection in those cities.",
        "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.",

        "question": "How do I get to Douglas Intl Airport from the city center?",
        "answer": "From downtown Charlotte, the Sprinter bus (Route 5) is the only direct public transit option to CLT, taking about 25 minutes and running frequently on weekdays. Ride-share services like Uber and Lyft are the most popular choice for their door-to-door convenience, usually taking 15–20 minutes, while taxis are available but less commonly used and can be pricier. Driving yourself is straightforward via I-85 or Wilkinson Boulevard, with various on-site parking options ranging from hourly to long-term economy lots. The Sprinter bus is the cheapest, ride-share is the fastest and most popular, and taxis are the most expensive.",
