        "question": "What is the typical flight duration from Baltimore to San Juan?",
        "answer": "The flight from Baltimore to San Juan is about 1,570 miles and typically takes 4 hours and 5 minutes nonstop. The return leg is slightly longer at 4 hours and 10 minutes, a small difference from prevailing winds. Southwest and Frontier both serve the route daily or near-daily with direct flights.",
        "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 Baltimore to San Juan?",
        "answer": "Yes, Southwest and Frontier both fly nonstop from Baltimore (BWI) to San Juan (SJU). Southwest operates up to 67 weekly flights — essentially daily with multiple departures throughout the day — while Frontier runs about 16 weekly flights on all days except Tuesday. A few late-night red-eye options are also available: Frontier departs at 9:29 PM on Monday, Wednesday, and Friday, and Southwest has Sunday departures at 9:05 PM and 9:20 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. 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. 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.",

There is no limit on the length of stay for US nationals.\n\nThis is general guidance to help you plan, not official immigration advice — entry rules can change and can depend on your nationality and circumstances, so please confirm the current requirements with the relevant embassy or official government source before you travel.",

        "answer": "From Luis Muñoz Marín International Airport (SJU), the main ground transportation options to reach central San Juan are taxis, rideshare services like Uber, and rental cars; there is no direct rail link from the airport itself. The Tren Urbano metro system serves the broader San Juan metropolitan area, but its nearest station is not at the airport and requires a connecting bus or taxi. Taxis and rideshares are the most used and generally fastest for door-to-door trips to the city center, typically taking 15–25 minutes depending on traffic. Rental cars offer flexibility for exploring beyond San Juan but involve parking and traffic considerations. Public buses are available but are slower and less convenient for airport transfers.",

        "question": "When is the cheapest time to fly from Baltimore to San Juan?",
        "answer": "Average fares from BWI to San Juan bottom out around $228 in early October, making that the cheapest stretch to fly. October, September, and January are the cheapest months overall, with average fares of $232, $251, and $252 respectively, while late December is the most expensive period at an average of $346, with December, July, and March the priciest months at $319, $293, and $290.",
        "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.",

        "answer": "For Baltimore to San Juan, the best fares come when you book 4 to 6 weeks before departure, with average prices around $197. Booking about 30 days out yields the single lowest fare at roughly $196, while waiting until the last minute or booking more than 10 weeks ahead tends to push prices noticeably higher. Summer and holiday periods typically require booking a bit earlier than the 4-6 week sweet spot to lock in the lowest fares.",
        "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.",

Free BWI courtesy shuttles run 24/7 between the terminal, parking lots, and the Amtrak/MARC rail station every 10–15 minutes, providing easy access if you arrive by train or park off-site. Taxis are available at the lower-level arrivals roadway outside baggage claim, with no flat rates permitted, while app-based ride services like Uber and Lyft pick up and drop off at the departures/ticketing level of the terminal. Driving is straightforward via I-195, and BWI offers several on-airport parking options—daily garage, express lot, and long-term lots—served by the same frequent courtesy shuttles, though parking costs vary by lot and duration.",

        "question": "What aircraft are typically used on flights from Baltimore to San Juan?",
        "answer": "Southwest operates the most flights on the Baltimore to San Juan route, using the Boeing 737 family and specifically the Boeing 737-700. Frontier also flies the route, using the Airbus A320 family.",
        "methodology": "Aircraft types 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). For U.S. routes the type is grounded in the tail number that actually operated the flight; elsewhere it comes from the airline's filed equipment code. Where the source does not commit to a specific variant we name the aircraft family (for example Airbus A320 family) rather than guess, and where no reliable type is on file the aircraft is omitted rather than estimated. Types describe typical scheduled equipment and can vary with seasonal or day-of-week assignments and last-minute swaps.",

        "question": "Which airline alliances serve flights from Baltimore to San Juan?",
        "answer": "Southwest Airlines (WN) is not part of any global alliance, and Frontier Airlines (F9) is also unaffiliated, so there are no alliance carriers on the BWI–SJU nonstop route. Other alliances may serve it via connections, but neither Oneworld, Star Alliance, nor SkyTeam has a member operating nonstop here.",
        "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.",
