        "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.",

        "question": "What are the ground transportation options in San Juan?",
        "answer": "Taxis, ride-share services like Uber, and car rentals are available at San Juan's airport, with taxis offering fixed rates to zones like Old San Juan and Condado. Public buses are an option via the AMA system, but they are less convenient for visitors due to limited schedules and the need for exact change. Ride-share is popular for its ease and app-based convenience, while taxis remain the most used and readily available at the terminal, though they can be pricier. For the fastest trip to the city center, a taxi or ride-share takes about 10–20 minutes depending on your exact destination.",

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.",

        "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.

You can also take the MTA Light Rail directly to the terminal, which is slower but cheaper. Ride‑share services like Uber and Lyft, as well as taxis, offer door‑to‑door convenience at a higher cost, while driving yourself and parking in the daily garage or long‑term lots provides flexibility for longer trips.",
