        "question": "What is the typical flight duration from Nashville to San Diego?",
        "answer": "The nonstop flight from Nashville to San Diego is about 1,750 miles and typically takes 4 hours 20 minutes. The return leg from San Diego to Nashville is about 20 minutes shorter, at 4 hours flat.",
        "methodology": "Flight times and distances come 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). The typical flight time is the median scheduled block time across all carriers on the route, computed the same way in both directions so the difference reflects prevailing winds rather than any change in method. Distance is the great-circle distance between the two airports, so the actual flown track is typically 2-5% longer.",

        "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.",

        "question": "What are the ground transportation options in San Diego?",
        "answer": "San Diego International Airport (SAN) offers several ground transportation options to the city center. The most convenient public transit is the San Diego Metropolitan Transit System (MTS) Route 992 bus, which runs directly between the airport and downtown, with contactless tap-to-pay; the San Diego Flyer shuttle also connects terminals to the Old Town Transit Center for trolley access. Taxis and ride-hailing apps like Uber and Lyft are readily available curbside and offer the fastest door-to-door service, typically reaching downtown in 10–15 minutes. A Rental Car Center with major providers is on-site, served by a 24-hour shuttle, and car rentals are popular for exploring the wider region. Among these, ride-share and taxis are the most used for direct downtown trips due to speed and convenience, while the Route 992 bus is the primary low-cost public option.",

        "question": "When is the cheapest time to fly from Nashville to San Diego?",
        "answer": "Average fares on Nashville to San Diego bottom out around $303 in late January. The cheapest months overall are September ($308), January ($309), and February ($314), while the most expensive period is late December at $385, with December ($369), March ($357), and June ($354) as the priciest months.",
        "methodology": "Seasonal fares come from Priceline's own air booking-summary archive, analysed in-house and refreshed monthly. For each day of the year we take a representative round-trip fare, a blend of the 25th-percentile and average ticket price over the route's bookings, and smooth the series into a seasonal curve; the half-month low and high and the monthly figures quoted here are averages of that curve. Thin and international routes borrow their seasonal shape from the nearest busy routes, with the price level anchored to the route's own bookings.",

      "q5": {
        "question": "How far in advance should I book tickets from Nashville to San Diego?",
        "answer": "The optimal booking window for flights from Nashville to San Diego is roughly 6 to 9 weeks before departure, with average fares around $260 and the single cheapest day at 50 days out ($257). Booking much earlier (170 days) or later (0–5 days) tends to cost more, with prices climbing above $400 at the extremes. For summer and holiday periods, expect the window to shift slightly earlier — likely 8–12 weeks out — as demand pushes prices up and the best deals sell out sooner.",
        "methodology": "Booking-window guidance comes from the same monthly in-house analysis of Priceline's own air booking-summary archive. We aggregate the route's bookings by how many days before departure they were made, from about 180 days out to the day of travel, smooth the curve, and highlight the stretch of lead times with the lowest average fare. Thin and international routes borrow the curve shape from the nearest busy routes, anchored to the route's own price level. It reflects current fares and is refreshed monthly.",

        "answer": "Yes, Southwest operates nonstop red-eye flights from Nashville to San Diego on Tuesdays and Wednesdays, departing at 9:00 PM. The flight arrives the same night, 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.",

        "methodology": "On-time arrival 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; a flight counts as on time when it arrives within 15 minutes of schedule. Carriers are ranked by arrival on-time rate on this route, and the carrier list itself comes 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).",

        "question": "How do I get to Nashville Intl Airport from the city center?",

Taxis and ride-share services pick up at the Ground Transportation Center on Level 1 of Terminal Garage 2. Driving is straightforward via I-40 or the Donelson Pike exit, with parking available at the airport.

Where the source does not commit to a specific variant we name the aircraft family (for example Airbus A320 family) rather than guess, and where no reliable type is on file the aircraft is omitted rather than estimated.

        "question": "Which airline alliances serve flights from Nashville to San Diego?",
        "answer": "Only Southwest Airlines flies nonstop between Nashville and San Diego, and Southwest does not belong to any major global alliance — it is an independent carrier. Other alliances (such as Star Alliance, oneworld, and SkyTeam) may serve the route via connecting itineraries, but no nonstop service from alliance members exists.",
        "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, 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.",
