Return flights follow similar durations." }, "q1": { "question": "Are there any direct flights from Des Moines to San Juan?", "answer": "There are no nonstop flights from Des Moines (DSM) to San Juan (SJU). The quickest one-stop option typically connects through Chicago O'Hare (ORD) on United, taking around 7 hours and 45 minutes total with a short layover.

U.S. citizens and lawful permanent residents can travel with the same documents they use for any domestic flight, such as a REAL ID‑compliant driver’s license or passport.

Public buses operated by the AMA serve the airport area but have limited routes and require exact change or a contactless card, making them less convenient for visitors. Rental car counters are available at the airport for exploring beyond the city, though parking in Old San Juan is tight.

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 Des Moines to San Juan?", "answer": "For the best fare from Des Moines to San Juan, aim to book roughly 14–17 weeks ahead, where average prices settle around $623.

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.
