        "question": "What is the typical flight duration from Detroit to St. Louis?",
        "answer": "A nonstop flight from Detroit (DTW) to St. Louis (STL) typically takes about 1 hour 30 minutes to 1 hour 45 minutes. With one stop, depending on the connection city, total travel time often ranges from 3 to 5 hours."
      },
      "q1": {
        "question": "Are there any direct flights from Detroit to St. Louis?",
        "answer": "Yes, Southwest and Delta both fly nonstop from Detroit to St. Louis. Southwest operates 45 weekly flights and Delta 25, with departures spread throughout the day on both airlines. Service runs daily.",

        "answer": "From St. Louis Lambert International Airport (STL), the most used and fastest option to downtown is the MetroLink light rail, which offers direct, economical service in about 30 minutes. Taxis and ride-share services like Uber and Lyft are readily available for a quicker, door-to-door trip, while numerous on-site car rental agencies provide flexibility for those wanting their own vehicle. The airport is about 14 miles northwest of the city center, so driving or taking a ride-share typically takes 20–30 minutes without traffic.",

        "question": "When is the cheapest time to fly from Detroit to St. Louis?",
        "answer": "The cheapest months to fly from Detroit to St. Louis are October and August, with average fares around $241–$248, while June and March are the most expensive, averaging $342 and $324 respectively. Late summer and fall offer the lowest prices, whereas early summer and early spring see higher fares.",
        "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 Detroit to St. Louis?",
        "answer": "For the Detroit to St. Louis route, the best fares are typically found when booking 8 to 11 weeks ahead, with an average price around $216 during that window. The absolute lowest fare observed was $174 at 70 days out, while last-minute bookings can cost over $350. Summer and holiday periods usually require booking a bit further in advance to secure similar savings, as demand pushes optimal windows slightly earlier.",
        "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, overnight red-eye flights are available from Detroit (DTT) to St. Louis (STL). Southwest operates three weekly red-eyes departing at 9:10 PM on Mondays, Thursdays, and Fridays, while Delta runs one on Saturdays at 9:20 PM. Both departures are late evening and, given the short flight duration on this route, arrive the same night.",
        "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 Detroit to St. Louis?",
        "answer": "On‑time performance is generally good on this short route, but afternoon thunderstorms can cause delays. Early morning flights, especially on Delta, tend to depart on schedule."

      "q10": {

        "answer": "St. Louis Lambert International Airport is the only commercial airport serving the city. It is located about 14 miles northwest of downtown and handles all scheduled passenger flights."
      },
      "q13": {
        "question": "How do I get to Detroit Metro Airport from the city center?",
        "answer": "From downtown Detroit, you can reach DTW via the Detroit Air Xpress (DAX) express bus, which runs daily from 3:30 a.m. to 11 p.m. and costs $8 at the door or $6 in advance, offering a direct 30–40 minute trip. SMART public buses (routes 125, 261, 280) also serve the airport with lower fares but longer travel times. Ride‑share and taxis are available at both terminals, providing door‑to‑door convenience for a higher cost, while driving and parking at one of the on‑site lots is straightforward. The DAX bus is the fastest and most popular public option for its direct service and affordability.",
