Public buses (AMA) run a few routes from the airport, but service is infrequent and not well integrated with tourist areas; it's the cheapest option at $0.75 but rarely used by visitors. Car rentals are widely available and useful if you plan to explore beyond San Juan, though parking in the old city can be difficult. There is no direct rail link from the airport, but the Tren Urbano has a station nearby with a shuttle connection, though it's less convenient for most travelers.", "toolsUsed": [], "references": [ { "url": "https://en.wikipedia.org/wiki/Luis_Mu%C3%B1oz_Mar%C3%ADn_International_Airport", "title": "Luis Muñoz Marín International Airport", "favicon": "https://en.wikipedia.org/static/apple-touch/wikipedia.png", "time_published": "2026-07-21T20:24:02Z" }, { "url": "https://en.wikipedia.org/wiki/List%20of%20the%20busiest%20airports%20in%20Puerto%20Rico", "title": "List of the busiest airports in Puerto Rico", "time_published": "2025-09-20T07:52:17Z" }, { "url": "https://en.wikipedia.org/wiki/Luis_Mu%C3%B1oz_Marin_International_Airport", "title": "Luis Muñoz Marín International Airport - Wikipedia", "time_published": "2002-09-10T02:45:15Z" }, { "url": "https://en.wikipedia.org/wiki/List_of_the_busiest_airports_in_Puerto_Rico", "title": "List of the busiest airports in Puerto Rico", "favicon": "https://en.wikipedia.org/static/apple-touch/wikipedia.png", "time_published": "2025-09-20T07:52:17Z" }, { "url": "https://en.wikipedia.org/wiki/Puerto%20Rico%20Metropolitan%20Bus%20Authority", "title": "Puerto Rico Metropolitan Bus Authority", "time_published": "2026-01-08T02:20:19Z" } ] }, "q4": { "question": "When is the cheapest time to fly from Charleston to San Juan?", "answer": "The cheapest months to fly from Charleston to San Juan are September, February, and April, with average fares around $363–$375, while October and August are also relatively low.

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.
