        "question": "What is the typical flight duration from Boston to St. Louis?",
        "answer": "A nonstop flight from Boston (BOS) to St. Louis (STL) typically takes about 3 hours to 3 hours 15 minutes. With one stop, depending on the layover city, total travel time often ranges from 5 to 7 hours. The return flight is usually similar in duration, though headwinds can sometimes make the westbound leg slightly longer."
      },
      "q1": {
        "question": "Are there any direct flights from Boston to St. Louis?",
        "answer": "Yes, Southwest and American fly nonstop from Boston to St. Louis. Southwest runs up to 84 weekly flights daily, while American (operated by Envoy and Republic) offers another 40 weekly departures — daily on Envoy, and twice daily Monday through Friday plus Sunday on Republic. Together they provide over 120 nonstop flights a week, with departures spread from early morning through evening.",
        "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.",

        "answer": "From St. Louis Lambert International Airport, the MetroLink light rail provides a direct and economical connection to downtown and other areas, making it a popular choice. Taxis, ride-sharing services like Uber and Lyft, and numerous car rental agencies are also available for flexible travel. The MetroLink is often the most used option for cost and efficiency, with a trip to downtown taking about 30 minutes.",

        "question": "When is the cheapest time to fly from Boston to St. Louis?",
        "answer": "The cheapest months to fly from Boston to St. Louis are October and September, with average fares around $306 and $318 respectively. The most expensive months are March and July, where average prices reach $467 and $461.",
        "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.",

        "question": "How far in advance should I book tickets from Boston to St. Louis?",
        "answer": "For the best fare on the Boston to St. Louis route, book between 5 and 25 days before departure, when average prices are around $325. Booking extremely early — 145 days out — can cost as much as $509, and last-minute tickets (day of departure) are also relatively high at $428.",
        "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.",

        "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.",

Southwest operates the most, with 84 weekly flights spread throughout the day, while the two American Eagle affiliates together add 40 weekly flights. Typical fares on the route are not available in the current data.",

      },
      "q9": {
        "question": "How reliable are on‑time departures on this route from Boston to St. Louis?",
        "answer": "On‑time departures are generally reliable, though afternoon and evening flights can be affected by weather or air traffic. Early morning flights, particularly on Southwest and Delta, tend to have better on‑time performance."
      },
      "q10": {
        "question": "Which months have the best weather for traveling to St. Louis?",

        "question": "Which airport should I use in St. Louis?",
        "answer": "St. Louis Lambert International Airport is the only commercial airport serving the city, located about 14 miles northwest of downtown. It offers a range of domestic flights and is the primary choice for all travellers."
      },
      "q13": {
        "question": "How do I get to Logan Intl Airport from the city center?",
        "answer": "From downtown Boston, the MBTA Silver Line SL1 bus offers a direct, free connection from South Station to all Logan terminals, making it the most popular and economical choice. The Blue Line subway to Airport station is another public transit option, connecting to a free shuttle bus to the terminals. Logan Express buses serve Back Bay and suburban locations with comfortable, low-cost rides, while taxis and ride-shares like Uber and Lyft provide door-to-door convenience at a higher price. Driving and parking at the airport is also possible, with garages and advance reservations available, though it's generally the most expensive option given downtown traffic and daily rates.",
