        "question": "What is the typical flight duration from Boston to Washington?",
        "answer": "The flight from Boston to Washington is about 400 miles and typically takes 1 hour 48 minutes. The return trip is slightly shorter at 1 hour 39 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": "From Reagan National (DCA), the most-used and fastest option to downtown Washington is the Metrorail, with a station directly connected to Terminal 2 via the Blue and Yellow Lines for a quick, affordable ride. Taxis are available at the curb outside baggage claim, while ride shares like Uber and Lyft can be summoned via smartphone. On-airport rental car counters are located in Terminal Garage 1, with a shuttle or a 10-15 minute walk to reach them. Shuttle vans like SuperShuttle also provide shared rides, but the Metro is generally the top choice for speed and convenience.",

        "question": "When is the cheapest time to fly from Boston to Washington?",
        "answer": "The cheapest months to fly from Boston to Washington are September, August, and October, with average fares as low as $191 in September. The most expensive months are May, April, and December, when average fares reach up to $304.",
        "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 Washington?",
        "answer": "For Boston to Washington, the best fares generally appear when booking 9 to 11 weeks ahead, with an average price around $161. Booking about 80 days out can yield the lowest typical fare near $156, while waiting until the last minute pushes prices toward $288. Around summer and holiday peaks, it's wise to book a few weeks earlier than usual, as demand can shrink the window for the cheapest seats.",
        "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 Washington?",
        "answer": "Yes, overnight red-eye flights are available nonstop from Boston to Washington. Republic Airways (operating for a mainline brand) runs a daily departure around 9:55–9:59 PM and American Airlines departs around 9:06 PM six days a week (Monday through Friday and Sunday). These late-evening flights are short hops, so they land the same night before midnight.",
        "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.",

        "question": "Which airlines usually operate this route from Boston to Washington?",
        "answer": "JetBlue, American Airlines, and Delta (with flights operated by Republic) all offer nonstop service from Boston to Washington, D.C., with hundreds of weekly flights combined. JetBlue operates around 170 weekly flights, often with the lowest median fare at about $306, while American has about 149 weekly flights with a median fare near $337. Delta's service, operated by Republic, is the most frequent at roughly 256 weekly flights, though its median fare wasn't reported. All three carriers fly daily with departures spread throughout the day.",
        "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.

        "question": "If I need a connection, what are common layover cities between Boston and Washington?",
        "answer": "Common layover cities between Boston and Washington include New York (JFK/LGA), Philadelphia, and Newark. These hubs offer frequent flights and efficient transfers, keeping total travel time competitive. New York and Philadelphia serve as major domestic hubs with numerous daily connections, while Newark provides a straightforward routing slightly west of the direct path. All are within the United States, so no transit visas are required for domestic passengers."
      },
      "q9": {
        "question": "How reliable are on‑time departures on this route from Boston to Washington?",

American posts a 78.4% on‑time departure rate with a 2.5% cancellation rate, while Delta‑ and American‑branded flights operated by Republic show 76.7% on‑time departures and a 3.4% cancellation rate.",

        "question": "Which airport should I use in Washington?",
        "answer": "Reagan National is closest to downtown and the National Mall, ideal for business and tourism. Dulles is farther out, serves more international flights, and is a United hub. Baltimore/Washington is the farthest but often has lower fares on Southwest."
      },
      "q13": {
        "question": "How do I get to Logan Intl Airport from the city center?",
        "answer": "From downtown Boston, the MBTA’s Blue Line subway and free Silver Line bus (SL1) connect to all terminals, with the Silver Line departing from South Station and the Blue Line from Airport Station via a free shuttle. The Logan Express bus provides direct service from Back Bay, while ride‑share apps, taxis, and parking are also available. The Silver Line is often the most popular public transit choice for its direct, frequent service, and public transit is generally the cheapest option, with Logan Express and ride‑shares or taxis costing progressively more.",
