        "question": "What is the typical flight duration from Kathmandu to Washington?",
        "answer": "There are no nonstop flights from Kathmandu (KTM) to Washington Dulles (IAD). The shortest one-stop journeys, commonly via Doha or Dubai, take about 19 to 22 hours total travel time. Return flights from Washington to Kathmandu are similar in duration, typically 20 to 23 hours depending on layover length."
      },
      "q1": {
        "question": "Are there any direct flights from Kathmandu to Washington?",
        "answer": "There are no nonstop flights from Kathmandu to Washington. The shortest way to make the trip is a one-stop connection, with Qatar Airways via Doha offering the quickest routing at about 27 hours total travel time (roughly 4h40m to Doha, a ~15-hour layover, then 14h20m to Washington). Turkish Airlines via Istanbul and Emirates via Dubai are also common one-stop options, though the majority of itineraries require two stops.",
        "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. Stop counts, connecting hubs, and per-airline prices are drawn from a large sample of the real fares Priceline users found on this route in the last 72 hours. We group those fares by number of stops, by the hub airport a connection routes through, and by operating airline, and report each group's share of the sample alongside its lowest and median price.",

        "question": "Are there visa requirements to travel from Kathmandu to Washington?",
        "answer": "Yes, there are visa requirements for travel between Kathmandu and Washington. If you are a Nepalese citizen, you need a visa to enter the United States. You must apply for a U.S. visa at the U.S. Embassy in Kathmandu before travel. If you are a U.S. citizen, you can obtain a visa on arrival in Nepal at Tribhuvan International Airport or apply in advance at a Nepalese embassy. For other nationalities, check both U.S. and Nepalese visa requirements based on your citizenship."

      "q3": {
        "question": "What are the ground transportation options in Washington?",
        "answer": "Washington Dulles International Airport (IAD) offers several ground transportation options to the city center, including the Silver Line Metrorail via a $5 express bus to Wiehle-Reston East station, Washington Flyer taxi cabs available 24/7, ride-share services like Uber and Lyft, shared vans, and rental cars. The Metrorail is the most cost-effective and commonly used option, though no rail service runs overnight. Taxis and ride-shares provide the fastest, most direct trip, especially outside Metrorail hours. Shared vans and rental cars are also available but are less popular for downtown access.",

        "question": "When is the cheapest time to fly from Kathmandu to Washington?",
        "answer": "The cheapest months to fly from Kathmandu to Washington are August, September, and April, with average fares around $1,457 to $1,527, while December, June, and July are the most expensive, averaging $1,823 to over $2,000.",
        "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 Kathmandu to Washington?",
        "answer": "For the Kathmandu to Washington route, the optimal booking window is about 6 to 9 weeks before departure, with average fares around $1,640. The single cheapest fare appears around 50 days out at $1,633, while last-minute tickets can exceed $2,000. During peak summer and holiday periods, booking on the earlier side of this window—closer to 9 weeks—is advisable to avoid steeper price hikes.",
        "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 — neither nonstop nor connecting itineraries with a red-eye long leg appear in the schedule.",
        "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 is no nonstop service between Kathmandu and Washington, D.C. Common one-stop connections include Qatar Airways via Doha (up to 9 daily patterns), Emirates via Dubai (4 daily patterns), and Turkish Airlines via Istanbul (2 daily patterns). These carriers operate the long-haul segments and connecting flights on their own metal. Specific per-carrier fares are not provided in the available data.",

      },
      "q9": {
        "question": "How reliable are on‑time departures on this route from Kathmandu to Washington?",
        "answer": "On-time performance can be variable due to weather and operational factors at Kathmandu airport; early morning departures often have better reliability. Airlines like Qatar Airways and Turkish Airlines typically maintain solid punctuality."
      },
      "q10": {
        "question": "Which months have the best weather for traveling to Washington?",

        "question": "What documents should I bring with me to the airport when flying from Kathmandu to Washington?",

      },
      "q12": {
        "question": "Which airport should I use in Washington?",
        "answer": "Washington Dulles is the primary international gateway, about 26 miles from downtown, and is a hub for United Airlines. Ronald Reagan National is closer to the city centre and the National Mall, making it more convenient for domestic connections and business travellers. Baltimore/Washington International is the farthest out but often offers lower fares and serves as a major Southwest focus city."
      },
      "q13": {
        "question": "How do I get to Tribhuvan Intl Airport from the city center?",
        "answer": "From central Kathmandu, taxis and ride‑sharing apps like Pathao are the most popular and quickest way to reach Tribhuvan International Airport, taking about 20–30 minutes depending on traffic. Pre‑paid taxis are available at the airport counter and offer fixed fares, while metered street taxis are cheaper but require negotiation. Public buses run from Ratna Park and other city stops to the airport gate, but they are slow and crowded, so they are rarely used by travelers with luggage. There is no dedicated airport shuttle bus, and driving yourself is not recommended because airport parking is limited and chaotic.",
