        "question": "What is the typical flight duration from Madrid to Washington?",
        "answer": "A nonstop flight from Madrid (MAD) to Washington (IAD) typically takes about 8 hours 30 minutes eastbound. The return westbound flight is longer, usually around 9 hours 10 minutes. With a layover, total travel time often ranges from 11 to 14 hours depending on the connection."
      },
      "q1": {
        "question": "Are there any direct flights from Madrid to Washington?",
        "answer": "Yes, Iberia and United both fly nonstop from Madrid to Washington Dulles (IAD). The service is daily on both carriers — United operates one flight a day and Iberia runs two, giving a combined 17 weekly nonstops. There are no nonstop flights into Washington National (DCA); all direct Madrid–Washington service lands at Dulles.",
        "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.",

        "question": "Are there visa requirements to travel from Madrid to Washington?",
        "answer": "Yes, there are visa or travel authorization requirements for the Madrid to Washington route. For U.S. citizens traveling to Spain (Schengen area), no visa is required for stays up to 90 days within a 180-day period for tourism or business, but a valid passport is needed; starting in 2025, the European Travel Information and Authorization System (ETIAS) will be required for visa-exempt travelers, including U.S. citizens. For Spanish citizens traveling to the U.S., they can travel visa-free under the Visa Waiver Program for stays up to 90 days, but must obtain an approved ESTA authorization before departure. Travelers of other nationalities should check both U.S. and Schengen visa requirements based on their citizenship."
      },
      "q4": {
        "question": "When is the cheapest time to fly from Madrid to Washington?",
        "answer": "The cheapest months to fly from Madrid to Washington are October, November, and September, with average round-trip fares around $562, $584, and $610 respectively. The most expensive months are June, July, and May, where average prices climb to $1009, $867, and $847.",
        "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. For this route, fares for the requested travel direction were unavailable, so the pattern shown is derived from the reverse direction, which shares the same seasonal demand cycle.",

      },
      "q5": {
        "question": "How far in advance should I book tickets from Madrid to Washington?",
        "answer": "For flights from Madrid to Washington, the best fares are typically found when booking 8 to 11 weeks before departure, with an average price around $773. The absolute cheapest window is about 55 days out, at $770, while last-minute bookings can cost $895 or more. During peak summer and holiday periods, prices tend to rise and the optimal booking window may shift earlier, so booking 10–12 weeks ahead is advisable for those travel dates.",
        "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. For this route, fares for the requested travel direction were unavailable, so the pattern shown is derived from the reverse direction, which shares the same seasonal demand cycle.",

        "answer": "No overnight (red‑eye) flights operate from Madrid to Washington — neither nonstop nor connecting itineraries with a red‑eye long leg are available on this route.",
        "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 Madrid to Washington?",
        "answer": "Iberia and United fly nonstop from Madrid to Washington. Iberia operates 10 weekly flights, while United operates 7 weekly flights — both daily services to Dulles (IAD). Typical per-carrier fares aren't available in the schedule data, but both airlines offer regular nonstop connections.",
        "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).

        "question": "How reliable are on‑time departures on this route from Madrid to Washington?",
        "answer": "Departures are generally punctual, though afternoon flights face higher delay risks due to congestion. Early morning flights, particularly on Iberia, tend to be more reliable."

      },
      "q12": {
        "question": "Which airport should I use in Washington?",
        "answer": "Washington has three airports. Dulles is the primary international gateway, located further from downtown. Reagan National is closest to the city centre and monuments, mainly serving domestic routes. Baltimore/Washington is farther north, handling low-cost carriers and some international flights."
      },
      "q14": {
        "question": "Are there hotels or sleeping facilities at Washington airport?",
        "answer": "Washington Reagan National Airport (DCA) does not have on-site hotels, capsule hotels, or sleeping pods inside the terminals. Several nearby hotels, such as the Courtyard Arlington Crystal City/Reagan National Airport and the Crystal City Marriott at Reagan National Airport, are within a 5-minute trip and offer free airport shuttles.",
