        "question": "What is the typical flight duration from Detroit to San Juan?",
        "answer": "The flight from Detroit to San Juan is about 1,930 miles and typically takes 4 hours 20 minutes nonstop. The return leg is longer at 4 hours 48 minutes, a difference driven by prevailing winds.",
        "methodology": "Flight times and distances come 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). The typical flight time is the median scheduled block time across all carriers on the route, computed the same way in both directions so the difference reflects prevailing winds rather than any change in method. Distance is the great-circle distance between the two airports, so the actual flown track is typically 2-5% longer.",

        "question": "Are there any direct flights from Detroit to San Juan?",
        "answer": "Delta flies nonstop from Detroit to San Juan twice daily, every day of the week, with departures around 8:25 AM and 8:56 AM. The flight takes about 4 hours and 20 minutes, and the return from San Juan is roughly 4 hours and 48 minutes due to prevailing winds.",
        "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, 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": "Ground transportation options from Luis Muñoz Marín International Airport to San Juan include taxis, ride share services, public buses (Metropolitan Bus Authority), the Tren Urbano metro system, and rental cars. The airport is connected to the city via the Teodoro Moscoso Bridge and the Baldorioty de Castro Expressway (PR-26). Taxis and ride share are generally the fastest and most convenient for direct city-center access, while rental cars are popular for exploring beyond San Juan. The Tren Urbano offers an affordable rail option but does not directly serve the airport, requiring a bus or taxi connection. Taxis are the most commonly used mode for airport-to-city transfers due to their availability and fixed-rate zones.",

        "question": "When is the cheapest time to fly from Detroit to San Juan?",
        "answer": "Average fares on the Detroit to San Juan route bottom out around $305 in late September, with September, August, and July being the cheapest months overall at $307, $308, and $319 respectively. The most expensive time to fly is late December, when average fares climb to about $423, making the holiday period the priciest stretch of the year.",
        "methodology": "Seasonal fares come from Priceline's own air booking-summary archive, analysed in-house and refreshed monthly. For each day of the year we take a representative round-trip fare, a blend of the 25th-percentile and average ticket price over the route's bookings, and smooth the series into a seasonal curve; the half-month low and high and the monthly figures quoted here are averages of that curve. Thin and international routes borrow their seasonal shape from the nearest busy routes, with the price level anchored to the route's own bookings.",

        "question": "How far in advance should I book tickets from Detroit to San Juan?",
        "answer": "For Detroit to San Juan, the best fares are found by booking about 4 to 7 weeks ahead of departure, with the absolute lowest price around 35 days out at roughly $235. Booking further in advance, especially 15 weeks or more out, tends to cost notably more, and prices also climb sharply inside three weeks, so for summer or holiday travel you'll want to stay on the early side of that 4–7 week window.",
        "methodology": "Booking-window guidance comes from the same monthly in-house analysis of Priceline's own air booking-summary archive. We aggregate the route's bookings by how many days before departure they were made, from about 180 days out to the day of travel, smooth the curve, and highlight the stretch of lead times with the lowest average fare. Thin and international routes borrow the curve shape from the nearest busy routes, anchored to the route's own price level. It reflects current fares and is refreshed monthly.",

The long red‑eye leg from Orlando departs at 23:17 and arrives in San Juan at 02:15 in the early hours, while the Tampa leg departs at 21:50 and arrives at 00:56 the same night.",
        "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 Detroit Metro Airport from the city center?",
        "answer": "From downtown Detroit, the Detroit Air Xpress (DAX) bus runs daily from 3:30 AM to 11 PM and is the most direct public transit option, costing $6 if purchased in advance (or $8 on board). SMART fixed-route and FAST limited-stop buses also serve both terminals, while the Michigan Flyer and AirRide connect from Ann Arbor and East Lansing. Ride-share services and taxis are available at the Ground Transportation Centers, and driving is straightforward with short-term and long-term parking at both terminals. The DAX bus is the most popular budget-friendly choice, while driving or a taxi is fastest but pricier.",
