        "question": "What is the typical flight duration from Nashville to San Diego?",
        "answer": "A nonstop flight from Nashville (BNA) to San Diego (SAN) typically takes about 4 hours 20 minutes to 4 hours 35 minutes. With one stop, common layovers like Denver or Dallas add travel time, often totaling 6 to 8 hours. The return nonstop is usually similar, around 4 hours eastbound."
      },
      "q1": {
        "question": "Are there any direct flights from Nashville to San Diego?",
        "answer": "Southwest is the only airline flying nonstop from Nashville to San Diego, with up to 81 weekly flights operating daily. Departures are spread throughout the day from early morning (around 6:00 AM) through late evening (around 9:00 PM), giving you plenty of options.",
        "methodology": "Airlines and weekly frequencies are compiled from our flight-schedule database, which combines published airline timetables, U.S. government schedule data from the Bureau of Transportation Statistics (BTS), and observed flight operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI). We count each operating carrier's scheduled weekly departures and the days it flies; where there is no nonstop service, connecting carriers are identified by linking scheduled nonstop segments through common hub airports. Where a median fare is shown for a carrier, it reflects the real fares Priceline users found on this route in the last 72 hours. Carrier service and weekly frequencies are summarized 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). Where available, on-time and cancellation rates come from the U.S. Bureau of Transportation Statistics (BTS) Airline On-Time Performance dataset, and typical fares from the U.S. DOT Airline Origin and Destination Survey (DB1B), a quarterly 10% sample of tickets sold.",

        "question": "What are the ground transportation options in San Diego?",
        "answer": "At San Diego International Airport, the fastest and most-used option to reach the city center is ride share or taxi, with a typical drive of about 10 minutes. Public transit is available via the Metropolitan Transit System bus Route 992, which connects directly to downtown and the Santa Fe Depot transit hub. Rental cars are also on-site at a consolidated Rental Car Center. While bike and pedestrian access is possible, the airport's location on the harbor makes motorized transport the most practical for most travelers.",

        "question": "When is the cheapest time to fly from Nashville to San Diego?",
        "answer": "The cheapest months to fly from Nashville to San Diego are November and December, with average fares around $295 and $332, while the most expensive months are September and June, averaging $421 and $416.",
        "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.",

      "q5": {
        "question": "How far in advance should I book tickets from Nashville to San Diego?",
        "answer": "For flights from Nashville to San Diego, the best fares are typically found when booking 6 to 9 weeks before departure, averaging around $259. During summer or holiday periods, demand tends to push prices higher, so aiming for that same 6–9 week window or slightly earlier can help avoid peak surcharges.",
        "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.",

        "answer": "Yes, Southwest operates a nonstop red-eye from Nashville to San Diego, departing at 9:00 PM on Tuesdays and Wednesdays. The flight lands in San Diego the same evening, not the next morning.",
        "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.",

      },
      "q9": {
        "question": "How reliable are on‑time departures on this route from Nashville to San Diego?",
        "answer": "On-time reliability is generally good, but afternoon thunderstorms or air traffic can cause delays. Early morning flights, particularly on Southwest, tend to depart more punctually."
      },
      "q10": {
        "question": "Which months have the best weather for traveling to San Diego?",

        "question": "Which airport should I use in San Diego?",
        "answer": "San Diego has one main commercial airport, San Diego International Airport (SAN), located just 3 miles from downtown and convenient to attractions like the Gaslamp Quarter and Balboa Park."
      },
      "q13": {
        "question": "How do I get to Nashville Intl Airport from the city center?",
        "answer": "From downtown Nashville, you can take WeGo Public Transit bus Route 18 directly to the airport, or grab a taxi for a quick 15‑minute trip to the terminal. Ride‑share services like Uber and Lyft also pick up from the city center, and several shuttle companies offer shared rides to BNA. Driving yourself is an option, with multiple parking lots and garages available at the airport. The taxi and ride‑share are the fastest and most popular choices, while the bus is the most affordable.",
