        "question": "What is the typical flight duration from Kathmandu to Washington D.C.?",
        "answer": "There are no nonstop flights from Kathmandu (KTM) to Washington D.C. (WAS). The typical total travel time with one or two layovers is 20 to 26 hours, depending on the connection. Common layover cities include Doha, Dubai, and Istanbul, with Doha often offering the shortest total journey around 20 hours. Eastbound flights via Europe can be slightly longer, and return flights from Washington to Kathmandu are typically similar in duration. Qatar Airways and Turkish Airlines are among the carriers frequently offering competitive timings on this route."

      "q1": {
        "question": "Are there any direct flights from Kathmandu to Washington D.C.?",
        "answer": "There are no nonstop flights from Kathmandu (KTM) to Washington, D.C. (WAS). The shortest one-stop routing is typically via Doha (DOH) on Qatar Airways, with a total journey time around 17–18 hours including a roughly 12.5-hour layover in Doha.",
        "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": "Are there visa requirements to travel from Kathmandu to Washington D.C.?",
        "answer": "Yes, there are visa requirements. Nepali citizens must obtain a U.S. visa before traveling to Washington D.C. U.S. citizens need a visa to enter Nepal, which can be obtained on arrival at Kathmandu airport or in advance from a Nepalese embassy or consulate. Travelers of other nationalities should check both U.S. and Nepalese entry requirements based on their citizenship."

        "question": "What are the ground transportation options in Washington D.C.?",
        "answer": "Washington D.C. is served by three major airports. From Ronald Reagan Washington National Airport (DCA), the Washington Metro’s Yellow and Blue Lines provide a quick and affordable fifteen-minute ride to downtown. Taxis and ride-shares take about the same time but cost more. From Washington Dulles International Airport (IAD), the Silver Line Express Bus connects to the Wiehle-Reston East Metro station, and since November 2022 the Silver Line Metro extension directly serves the airport, reaching the city center in about sixty minutes. Taxis and ride-shares from Dulles take forty to sixty minutes depending on traffic and are more expensive. Baltimore/Washington International Airport (BWI) is linked by MARC and Amtrak trains to Union Station in thirty to forty minutes, with BWI Express buses also available. Taxis and ride-shares from BWI are the most costly and time-consuming option. Car rentals are available at all airports but are generally unnecessary for city travel due to traffic and parking challenges. The Metro is the most used and efficient option for reaching central D.C., particularly from DCA."

      "q4": {
        "question": "When is the cheapest time to fly from Kathmandu to Washington D.C.?",
        "answer": "The cheapest months to fly from Kathmandu to Washington D.C. are April (around $1511), March ($1524), and September ($1542), with the low season generally spanning February through April and September. The most expensive months are December (around $2204), June ($2025), and July ($1857), with peak prices typically in June, July, November, and December.",
        "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.",

        "question": "How far in advance should I book tickets from Kathmandu to Washington D.C.?",
        "answer": "For flights from Kathmandu to Washington D.C., the best fares are typically found when booking 2–5 weeks before departure, with an average price around $1,656. The absolute lowest fare appears about 30 days out at $1,642, while booking at the last minute can cost over $2,000. During summer and holiday periods, demand may shift the optimal window slightly earlier, so aiming for 4–6 weeks ahead can help secure a better deal.",
        "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 are available from Kathmandu to Washington, D.C. — neither as a nonstop nor as a connecting itinerary where the long leg is a red-eye.",
        "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.",

        "answer": "There are no nonstop flights from Kathmandu to Washington D.C. Common one-stop connecting options include Qatar Airways via Doha, Emirates (sometimes with a Flydubai first leg) via Dubai, and Turkish Airlines via Istanbul. These were the carriers shown in a recent schedule sample, though other airlines may also offer connections on this route.",

      },
      "q9": {
        "question": "How reliable are on‑time departures on this route from Kathmandu to Washington D.C.?",
        "answer": "On-time reliability is mixed due to weather, airport congestion, and the need for connections. Departures from Kathmandu can be delayed by fog, especially in winter. Early morning flights on airlines like Qatar Airways or Turkish Airlines often perform better, as they leave before afternoon weather builds. No single airline dominates, but choosing the first wave of departures improves your odds."

      },
      "q13": {
        "question": "How do I get to Tribhuvan Intl Airport from the city center?",
        "answer": "From central Kathmandu to Tribhuvan International Airport, taxis are the most popular and quickest, taking about 15–25 minutes depending on traffic. Ride‑share apps like Pathao and Tootle are available and slightly cheaper. Public buses run but are crowded and slow. Hotel shuttles offer convenience at a moderate cost.
