The airports are about 2,280 miles apart.", "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). We report the days of the week and the departure times each carrier operates. 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. Distance is the great-circle distance between the two specific airports named, so an actual flown track is typically 2-5% longer. Where shown, on-time departure and arrival rates and cancellation rates come from the U.S. Bureau of Transportation Statistics (BTS) Airline On-Time Performance dataset, which covers U.S. domestic routes only; where a typical fare is shown, it comes from the U.S. DOT Airline Origin and Destination Survey (DB1B), a quarterly 10% sample of tickets sold.", "toolsUsed": ["flight_schedule"]}, "q3": {"question": "What are the ground transportation options in San Juan?", "answer": "From Luis Muñoz Marín International Airport (SJU), you can reach central San Juan by taxi, ride-share, public bus (AMA), or rental car. Taxis and ride-shares are the fastest and most used options—a flat-rate taxi to Old San Juan or Condado takes about 15–25 minutes. The public bus (route E40 or T5) is the cheapest at $0.75 but slower and less frequent; you’ll need exact change or a contactless card. Rental cars are available at the airport if you plan to explore beyond the city. For most visitors, a taxi or ride-share is the easiest door-to-door choice.", "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 Des Moines to San Juan?", "answer": "The cheapest months to fly from Des Moines to San Juan are September, October, and August, with average fares dropping to $569, $583, and $622 respectively. Prices are highest in March, December, and June, averaging $771, $751, and $700, while the shoulder months of January, November, April, and May fall in between.", "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 Des Moines to San Juan?", "answer": "For flights from Des Moines to San Juan, the best fares are typically found when booking 14 to 16 weeks ahead, with an average price of $620. The absolute lowest fare, $614, appears around 135 days before departure, while last-minute bookings can cost over $830.", "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 Des Moines to San Juan?", "answer": "No overnight (red‑eye) flights operate from Des Moines to San Juan — neither nonstop nor connecting itineraries with a red‑eye long leg are currently scheduled on this route.", "methodology": "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.", "toolsUsed": ["redeye_flights"]}, "q7": {"question": "Which airlines usually operate this route from Des Moines to San Juan?", "answer": "No airline flies nonstop from Des Moines to San Juan.
