On the return leg, the flight is longer at about 4 hours 1 minute due to prevailing winds. Connecting itineraries are also available, with total journey times typically ranging from about 5 to 8 hours depending on the layover.", "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).

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.

Taxis and ride‑sharing services like Uber are the fastest and most common door‑to‑door choices, and all major car rental agencies have desks right at the terminal. Public buses (AMA) run several routes from the airport to the metro area and cost just $0.75, but they can be slow and require exact change or a contactless card.

The most expensive months are December, March, and January, with December averaging $650. Spring and early summer fall in between, with April offering moderate prices around $460.", "methodology": "This 'good deal' estimate shows a representative best price for each departure date across roughly a 12-month window (about 3 months back and 9 months forward). It is built from real flight prices found by Priceline users searching this route, accumulated into a price history for each departure date. Rather than weighting all of that history equally, we apply exponential time decay so recent prices dominate — a price seen yesterday counts almost in full, one from about a month ago roughly a third, and prices from a few months back very little — giving a figure that tracks today's market instead of a stale long-run average. Clear price outliers are removed before any calculation, departure dates with no observations are filled in from nearby dates, and the resulting curve is lightly smoothed so it reads as a clean seasonal trend rather than day-to-day noise.", "toolsUsed": ["seasonal_prices"]}, "q5": {"question": "How far in advance should I book tickets from Atlanta to San Juan?", "answer": "For flights from Atlanta to San Juan, the best time to book is about 6 to 9 weeks before departure, when average fares are around $437. The absolute cheapest day to buy is roughly 60 days out, at $432. During peak summer and holiday periods, demand can push prices higher, so aiming for the earlier end of that window or even slightly further out may help lock in a better fare.", "methodology": "This booking-window guidance is built from the same real flight prices found by Priceline users searching this route, re-grouped by how many days before departure each price was seen (from the departure day out to about 180 days ahead) across the route's price history. At each booking lead time we report the 25th-percentile price — the cheaper end of what travelers were quoted, rather than the rock-bottom minimum (which can be a fluke) or the average (which is pulled up by expensive last-minute fares). The buy-or-wait advice then applies a risk premium that grows as departure approaches, since seat availability shrinks and prices become less predictable; using that adjusted curve we flag windows where waiting is likely to save a meaningful amount (at least $20 or 5%) versus windows where booking now is the better call. Isolated single-day recommendations are filtered out, so the advice only reflects a window that holds for several days in a row.", "toolsUsed": ["booking_timing"]}, "q6": {"question": "Are overnight (red‑eye) flights available from Atlanta to San Juan?", "answer": "No nonstop red-eye flights operate from Atlanta to San Juan, but connecting red-eye itineraries are available via Orlando, Miami, or Tampa on Frontier.
