        "question": "Which cities in Puerto Rico can I fly to from San Diego?",
        "answer": "From San Diego you will most often connect through a major U.S. hub such as Dallas, Miami or Atlanta to reach San Juan's Luis Muñoz Marín International Airport, the main gateway into Puerto Rico. Smaller airports in Aguadilla and Ponce typically require an additional stop or a domestic connection, and are less practical from the West Coast. Most travelers fly into San Juan for its historic Old City, beaches and connections to the rest of the island."
      },
      "q1": {
        "question": "How long is the flight from San Diego to Puerto Rico?",
        "answer": "There are no non-stop flights from San Diego to Puerto Rico. A typical one-stop connection to San Juan takes about 9 to 11 hours eastbound and roughly 10 to 12 hours westbound, depending on the layover city and duration."
      },
      "q2": {
        "question": "Are there direct flights from San Diego to Puerto Rico?",
        "answer": "There are currently no non-stop flights from San Diego to Puerto Rico. The most common one-stop routings connect through major U.S. hubs like Atlanta, Dallas, Miami or New York, with total travel times typically ranging from about 7½ to 10 hours depending on the layover."
      },
      "q3": {
        "question": "Which airlines fly from San Diego to Puerto Rico?",
        "answer": "No non-stop flights. Common one-stop options from San Diego to Puerto Rico include American via Dallas/Fort Worth, Delta via Atlanta, and United via Houston."
      },
      "q4": {
        "question": "When is the cheapest time to fly from San Diego to Puerto Rico?",
        "answer": "The cheapest months to fly from San Diego to Puerto Rico are September, October, and August, with late summer and early fall offering the lowest fares, while December, March, and July are the most expensive. For the best deal, book about 9 to 11 weeks ahead, aim to depart on a Wednesday or Saturday, and choose an early-morning or late-night flight; peak summer and major holidays like Christmas push prices significantly higher.",
        "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. 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. The cheapest day of the week and time of day to depart are drawn from the same large sample of real fares Priceline users found on this route in the last 72 hours, grouped by the day of the week and by the time-of-day window of the outbound departure, with the lowest and average price reported for each."
      },
      "q5": {
        "question": "How far in advance should I book flights from San Diego to Puerto Rico?",
        "answer": "For San Diego to San Juan, the sweet spot is booking 9 to 11 weeks ahead, when average fares drop to about $508 — waiting until the last minute can push prices above $800, while booking too early (more than 20 weeks out) rarely beats the 9-to-11-week window.",

The typical price, the lowest fare, a 'great deal' threshold, and how fares are spread across price bands are summarized from a large sample of the real fares Priceline users found on this route in the last 72 hours, with a small fraction of extreme outlier fares excluded from the range."

      "q6": {
        "question": "What are the most popular cities to visit in Puerto Rico?",
        "answer": "In Puerto Rico, San Juan is the main entry with Old San Juan’s colonial charm and nightlife. Rincon and Isabela draw surfers, while Ponce offers history and museums. Vieques and Culebra are prized for pristine beaches and bioluminescent bays, reachable by short flights or ferries."
      },
      "q8": {
        "question": "Which airports in Puerto Rico are best to fly into from San Diego?",
        "answer": "From San Diego to Puerto Rico, Luis Muñoz Marín International Airport in San Juan is the primary gateway with the most flights and connections to the rest of the island. For a more relaxed start near the west coast beaches, fly into Rafael Hernández Airport in Aguadilla, though options are fewer."
      },
      "q12": {
        "question": "When is the best time of year to visit Puerto Rico?",
        "answer": "For Puerto Rico, mid-April to June and November to early December offer warm weather with fewer tourists and lower prices than peak winter and summer. Hurricane season runs June through November, so monitor forecasts."
      },
      "q13": {
        "question": "How do I get to San Diego Intl Airport from the city center?",
        "answer": "From downtown San Diego, you can reach San Diego International Airport (SAN) by taking the Metropolitan Transit System (MTS) bus Route 992, which provides direct service from the city center to the terminals. Ride‑share services like Uber and Lyft, as well as taxis, offer convenient door‑to‑door options and are typically the fastest and most popular choices, though they cost more than public transit. Driving yourself is straightforward via North Harbor Drive, with on‑airport parking available in several lots and garages, but this is generally the most expensive option when factoring in parking fees. Shuttle services are also available, including shared‑ride vans and hotel shuttles, providing a middle ground in cost and convenience.",
