        "question": "What is the typical flight duration from Detroit to Washington?",
        "answer": "The flight from Detroit to Washington is about 400 miles and typically takes around 1 hour 35 minutes. In the return direction, flights average 1 hour 40 minutes, a difference of just 5 minutes.",
        "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.",

        "question": "Are there any direct flights from Detroit to Washington?",
        "answer": "Yes, there are nonstop flights from Detroit (DTW) to Washington, D.C. — both to Reagan National (DCA) and Dulles (IAD). American (operated by Republic and PSA) and Delta fly DTW–DCA daily with a combined 21 daily departures, while United (operated by Republic) and Delta serve DTW–IAD daily with roughly 17 daily flights. All routes run daily except one Delta DTW–IAD departure which skips Saturday, and the flight takes about 90–100 minutes.",
        "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.",

        "answer": "At Ronald Reagan Washington National Airport (DCA), the fastest way into downtown Washington is the Metrorail, which has an elevated station connected directly to Terminals B and C and is the most-used option for easy, affordable access across the metro area. Ride-hailing apps like Uber and Lyft are available with designated pickup zones on the outer curb of both terminals, and taxis are also permitted. Rental cars and on-airport shuttle buses provide further flexibility, while local Metrobus route 5A and Fairfax Connector buses serve downtown D.C., Reston, and the Udvar-Hazy Air & Space Museum.",

        "question": "When is the cheapest time to fly from Detroit to Washington?",
        "answer": "Average fares from Detroit to Washington bottom out around $229 in late January, with January and February being the cheapest months overall at $235 and $240 respectively. The most expensive stretch is late March, when average fares climb to about $278, and July is the priciest month at $272 on average.",
        "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 Detroit to Washington?",
        "answer": "For Detroit to Washington, the best fares are typically found when booking 3 to 6 weeks before departure, averaging around $200, with the absolute lowest price at 25 days out ($199). Booking much earlier or later tends to cost more — prices rise to about $232 at 5 days and $264 at 155 days ahead. For summer and holiday periods, demand pushes fares higher, so you should book closer to the 6-week mark or even slightly earlier to lock in the best available price.",
        "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.",

Delta operates a daily red-eye from Detroit (DTW) to Reagan National (DCA) departing at 9:29 PM, and SkyWest (operating for a mainline partner) flies a daily red-eye from DTW to Dulles (IAD) with departures at 9:25 PM and 9:35 PM. Both flights depart in the late evening and, given the short flight time, 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.",

Delta operates the most flights, with up to 104 weekly departures split between Dulles and Reagan National, while American offers up to 64 weekly flights, all to Reagan National, and United flies up to 29 weekly flights to Dulles. Fares vary by carrier, with Delta typically around $158, American around $179, and United around $159.",
        "methodology": "Airlines and weekly frequencies 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). 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 typical fare is shown for a carrier, it is the median of the real fares Priceline users found on this route in the last 72 hours.",

American Eagle operated by PSA arrives on time 85.9% of the time (0.0% cancelled), while Delta Connection operated by SkyWest is at 78.5% on-time with a 0.5% cancellation rate. Delta mainline flights have a 73.5% on-time arrival rate and 1.1% cancellations.",
        "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.

        "question": "How do I get to Detroit Metro Airport from the city center?",
        "answer": "From downtown Detroit, the Detroit Air Xpress (DAX) bus runs daily from 3:30 a.m. to 11 p.m. to Detroit Metropolitan Wayne County Airport (DTW), with fares around $6–$8. SMART public buses (Routes 125, 280, and FAST 261) also serve both terminals from downtown and surrounding suburbs at a lower cost, but with more stops. Ride-share and taxi services are available at the Ground Transportation Centers and are generally the fastest door-to-door option, though more expensive. Driving yourself is popular for flexibility, with on-airport parking garages near both terminals, but parking fees add up for longer trips.",

        "question": "What aircraft are typically used on flights from Detroit to Washington?",
        "answer": "Delta Air Lines flies the most between Detroit and Washington, using Airbus A319s, Boeing 717-200s, and regional jets operated by SkyWest (Bombardier CRJ-900s, Embraer E175s, and CRJ family aircraft). American Airlines, via Republic Airways and PSA Airlines, flies Embraer E175s and Bombardier CRJ-700s. United Airlines, operated by Republic Airways, flies Embraer E175s.",
        "methodology": "Aircraft types 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). For U.S. routes the type is grounded in the tail number that actually operated the flight; elsewhere it comes from the airline's filed equipment code. 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. Types describe typical scheduled equipment and can vary with seasonal or day-of-week assignments and last-minute swaps.",
