        "question": "What is the typical flight duration from Delhi to Washington?",
        "answer": "There are no nonstop flights between Delhi (DEL) and Washington, D.C. (IAD/DCA). With one stop, the most common layovers are in the Middle East or Europe, and the total travel time typically ranges from 17 to 22 hours. Eastbound flights from Washington to Delhi are often about 1–2 hours shorter due to favorable tailwinds."
      },
      "q1": {
        "question": "Are there any direct flights from Delhi to Washington?",
        "answer": "There are no nonstop flights from Delhi to Washington. The shortest one‑stop connections are via Newark (United, about 15h 40m total) or New York JFK (American, roughly 16h 55m), both with an overnight long‑leg departing Delhi around 11:30 PM and arriving on the US East Coast the next morning. Air India also operates a Delhi–Washington nonstop on some schedules, but it does not appear in the current published timetable.",
        "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. 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": "Are there visa requirements to travel from Delhi to Washington?",
        "answer": "Yes. Indian citizens must obtain a U.S. visa before traveling to the United States, typically a B-1/B-2 visitor visa. U.S. citizens traveling to India must have a valid visa or an approved e-Visa for tourism, business, or medical purposes. Check the latest requirements before travel."

      "q4": {
        "question": "When is the cheapest time to fly from Delhi to Washington?",
        "answer": "The cheapest months to fly from Delhi to Washington are September, April, and August, with average fares around $813, $826, and $853 respectively. The most expensive months are December, June, and July, where average prices climb to about $1,181, $1,131, and $1,049.",
        "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 Delhi to Washington?",
        "answer": "For the best fares from Delhi to Washington, book 9–12 weeks before departure, when average prices are around $978. Booking about 65 days ahead can yield the lowest single fare at $972, while last-minute tickets at departure can cost $1,396. During peak summer and holiday periods, earlier booking within this window is advisable as prices tend to rise closer to 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.",

        "question": "Are overnight (red‑eye) flights available from Delhi to Washington?",
        "answer": "Yes, connecting red-eye itineraries are available from Delhi to Washington. The long overnight leg is typically on United Airlines departing Delhi at 11:35 PM and arriving at Newark at 6:20 AM (early hours), then connecting to Washington, or on Air India departing Delhi at 10:50 PM and arriving at JFK at 9:40 AM the next morning, then connecting onward.",

        "question": "If I need a connection, what are common layover cities between Delhi and Washington?",
        "answer": "Common layover cities include Dubai, Doha, Abu Dhabi, and London. Dubai and Doha offer efficient single-terminal transfers with extensive global networks. Abu Dhabi provides streamlined connections and visa-free transit for many nationalities. London serves as a major hub with broad onward connections, though transit visas may be required for some travelers. These hubs keep total travel time competitive, typically ranging from 16 to 20 hours."

        "question": "How reliable are on‑time departures on this route from Delhi to Washington?",
        "answer": "On‑time performance is generally dependable, though fog in Delhi can delay early mornings in winter. Mid‑morning departures on Air India often balance reliability and comfort."
      },
      "q10": {
        "question": "Which months have the best weather for traveling to Washington?",
        "answer": "April to May and September to October offer pleasant temperatures, blooming or colorful foliage, and fewer tourists than summer."

      },
      "q12": {
        "question": "Which airport should I use in Washington?",
        "answer": "Washington Dulles is the primary international gateway, serving Star Alliance and nonstop flights from Delhi. Ronald Reagan is closest to downtown and the National Mall, handling domestic flights. Baltimore/Washington is farther out and serves as a low‑cost alternative."
      },
      "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. Several nearby hotels like the Courtyard Arlington Crystal City/Reagan National Airport and Crystal City Marriott at Reagan National Airport offer free shuttle service to the airport, typically a 5-minute ride away.",
