        "question": "What is the typical flight duration from Boston to Austin?",
        "answer": "The flight from Boston to Austin covers about 1,700 miles and typically takes 4 hours and 25 minutes nonstop. The return from Austin is about 4 hours, roughly 25 minutes shorter due to prevailing winds.",
        "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.",

Capital Metro's high-frequency Route 20 bus provides the most affordable transit connection. Rental cars are on-site, and parking garages or economy lots are available for those driving themselves.",

        "question": "When is the cheapest time to fly from Boston to Austin?",
        "answer": "The cheapest months to fly from Boston to Austin are August, September, and July, with average fares as low as $281 in August. The most expensive months are December, November, and January, with average fares peaking at $619 in December.",
        "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 Boston to Austin?",
        "answer": "For flights from Boston to Austin, the best time to book is about 3–6 weeks before departure, with an average fare around $236. Booking around 25 days out can yield the lowest prices, while waiting until the last week or buying more than 4 months ahead tends to be more expensive.",
        "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.",

        "question": "Are overnight (red‑eye) flights available from Boston to Austin?",
        "answer": "No red-eye flights are available from Boston to Austin — there are no nonstop overnight flights on this route, and no connecting itineraries whose long leg is a red-eye were found.",
        "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.",

      "q7": {
        "question": "Which airlines usually operate this route from Boston to Austin?",
        "answer": "Delta, JetBlue, and Southwest all operate nonstop flights from Boston to Austin. Delta offers the most frequent service with 31 weekly flights, followed by JetBlue with 27 and Southwest with 19. Specific median fares for each carrier are not available in the current data, so typical pricing cannot be stated.",
        "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.",

      },
      "q9": {
        "question": "How reliable are on‑time arrivals on this route from Boston to Austin?",
        "answer": "JetBlue is the most reliable, with 74.6% of flights arriving on time and a 0.4% cancellation rate. Delta follows at 72.0% on time and 1.4% cancelled, while Southwest trails at 51.8% on time but with no cancellations recorded.",

        "question": "Which airport should I use in Austin?",
        "answer": "Austin has one commercial airport, Austin-Bergstrom International Airport, located about 8 miles southeast of downtown. It serves as a focus city for Southwest and hosts major carriers like American, United, and Delta, covering both domestic and limited international routes."
      },
      "q13": {
        "question": "How do I get to Logan Intl Airport from the city center?",
        "answer": "From downtown Boston, the fastest and most popular way to reach Logan Airport is the MBTA Blue Line subway, which connects directly to the airport terminals via a free shuttle bus; the Silver Line bus also offers a direct ride from South Station. Logan Express buses provide comfortable coach service from Back Bay and several suburban park-and-ride lots, while ride-share apps like Uber and Lyft, as well as taxis, offer door-to-door convenience at a higher cost. Driving and parking is possible with on-airport garages and advance reservations, but it is generally the most expensive option and subject to traffic. The Blue Line and Silver Line are the most economical choices, while ride-share and taxis balance speed and cost.",

        "question": "What aircraft are typically used on flights from Boston to Austin?",
        "answer": "On nonstop flights from Boston to Austin, the most common aircraft are the Airbus A220-200, operated by JetBlue, and the Boeing 737-800, flown by Southwest. Connecting itineraries most often use Boeing 737 variants — particularly the 737-800, 737 MAX 8, and 737 MAX 9 — on the longer leg, with American, United, and Southwest all operating these types through hubs like Dallas/Fort Worth, Chicago O'Hare, and Baltimore. The exact aircraft can vary by day and airline, and while specific onboard amenities aren't listed, Wi-Fi and seatback entertainment are widely available on these modern narrowbody fleets.",
        "methodology": "Aircraft types are taken from the equipment each operating carrier schedules on this route, drawn from published airline timetables and airline equipment schedules in our flight-schedule database. They describe typical scheduled aircraft and can vary with seasonal or day-of-week assignments and last-minute equipment swaps.",

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.",
