        "question": "What is the typical flight duration from Detroit to St. Louis?",
        "answer": "The nonstop flight from Detroit to St. Louis covers about 440 miles and typically takes 1 hour 35 minutes, while the return leg is slightly shorter at 1 hour 30 minutes. Southwest and Delta both operate the route daily.",
        "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.",

      "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 daily. Southwest runs about 45 flights a week with departures spread from early morning through late evening, while Delta operates around 25 weekly flights with five daily departures. The flight takes roughly an hour and a half in the air.",
        "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. 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.",

        "answer": "From St. Louis Lambert International Airport (STL), the MetroLink light rail offers direct and economical service to downtown in about 30 minutes, making it the most-used public transit option. Taxis and ride-share services like Uber and Lyft are readily available for door-to-door convenience, while several on-site car rental agencies provide flexibility for onward travel. The MetroLink is the fastest budget-friendly choice, but ride-share or taxi is quickest overall, typically taking 15–20 minutes to the city center.",

        "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.",

Booking too early (180 days out) can cost nearly $360, while last-minute tickets jump back up to around $299. Summer and holiday periods shift this window earlier — aim for 8-12 weeks out to beat seasonal demand spikes.",
        "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.

        "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.",

Ride‑share services like Uber and Lyft, along with taxis, provide a faster door‑to‑door trip in about 25–35 minutes at a higher cost. Driving yourself takes a similar time and both terminals have parking, but you'll pay daily garage or lot rates.",

        "answer": "The nonstop service on this route is operated by Southwest Airlines, and the specific aircraft type isn't publicly listed for those flights — it's shown as unspecified, though Southwest's fleet is all Boeing 737s so you can expect a 737 variant. On connecting itineraries, the most common long-leg aircraft are the Bombardier CRJ-550, Embraer 175, Embraer 170, and Boeing 737-800, typically routing through Chicago O'Hare, with other connections via Dallas/Fort Worth, Denver, or Nashville on Boeing 737s and Airbus A319s. The exact aircraft can vary by day and airline, and while Wi-Fi and seatback entertainment are widely available, the specifics depend on the carrier and particular aircraft assigned.",
        "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.",
