        "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. (IAD). A typical one-stop journey takes around 19 to 22 hours, depending on the layover city. Common connections include Doha (Qatar Airways), Dubai (Emirates, flydubai), Istanbul (Turkish Airlines), and Abu Dhabi (Etihad). The fastest one-stop options often route through the Middle East and total roughly 19 hours. The return flight (IAD to KTM) is usually similar in duration, though westbound flights may be slightly longer due to prevailing winds."

      "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. (IAD). The shortest connecting routing is typically via Doha (DOH) on Qatar Airways, with a total journey around 18–19 hours including a layover of about 12–15 hours; Emirates via Dubai (DXB) and Turkish Airlines via Istanbul (IST) are other one-stop options, each taking roughly 19–21 hours.",
        "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. 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. Aircraft types are taken from the equipment each operating carrier schedules on this route, drawn from published airline timetables and airline equipment schedules in our flight-schedule database. They describe typical scheduled aircraft and can vary with seasonal or day-of-week assignments and last-minute equipment swaps.",

        "question": "Are there visa requirements to travel from Kathmandu to Washington D.C.?",
        "answer": "Yes, there are visa requirements for travel from Kathmandu, Nepal to Washington D.C., United States. Nepalese citizens generally need a U.S. visa, such as a B-1/B-2 visitor visa, to enter the United States. They are not eligible for the Visa Waiver Program or ESTA. U.S. citizens do not need a visa to enter the U.S. but must present a valid U.S. passport. For the return from Washington D.C. to Kathmandu, 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. Non-U.S. and non-Nepalese nationals should check visa requirements based on their nationality for both countries."

        "question": "What are the ground transportation options in Washington D.C.?",
        "answer": "Washington Dulles International Airport offers several options to reach downtown D.C. The Silver Line Express bus connects to the Wiehle-Reston East Metro station in about 15 minutes, from where the Metro’s Silver Line takes you to the city center in roughly 45 minutes. This is the most used public transit route. Alternatively, the Metrobus 5A is a slower, cheaper bus to Rosslyn. Taxis and ride-share services take 40 to 60 minutes depending on traffic, costing $60 to $80. Car rentals are available but driving and parking in D.C. can be difficult. Shared shuttle vans are an economical middle ground. Most visitors use the Silver Line Express plus Metro combination for its balance of speed and cost."

        "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, March, and September, with average round-trip fares around $1,511, $1,524, and $1,542, respectively. The most expensive months are December, June, and July, where average fares climb to $2,204, $2,025, and $1,857.",
        "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 the best fare from Kathmandu to Washington D.C., aim to book 2–5 weeks before departure, with the lowest price around $1,642 about 30 days out. Prices rise closer to departure, exceeding $2,000 for last-minute bookings, and remain fairly stable farther in advance, so there's little advantage to booking more than two months ahead.",
        "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.",

        "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": "If I need a connection, what are common layover cities between Kathmandu and Washington D.C.?",
        "answer": "Common one-stop hubs include Doha, Dubai, and Istanbul. Doha and Dubai offer efficient connections via Qatar Airways and Emirates, while Istanbul provides a single layover with broad US-bound options. European hubs like London or Frankfurt are possible but often involve longer total travel time and additional visa considerations for Nepali passport holders unless they qualify for transit exemptions."

      "q12": {
        "question": "Which airport should I use in Washington D.C.?",
        "answer": "For Washington D.C., the three main airports are Dulles International (IAD), Reagan National (DCA), and Baltimore/Washington International (BWI). Dulles (IAD) is your listed destination, located about 26 miles west of downtown D.C., and serves as a major international gateway for Star Alliance carriers like United and Lufthansa. Reagan National (DCA) is closest to downtown, just across the Potomac River, and is ideal for domestic flights and quick access to monuments and government buildings, with American Airlines as a dominant carrier. Baltimore/Washington (BWI) is about 30 miles northeast of D.C. and is a base for Southwest's low-cost domestic services, with some international flights. Choose IAD for international arrivals, DCA for proximity to the city center, or BWI for budget options."

        "answer": "From central Kathmandu to Tribhuvan Airport, taxis are the most popular and take about 20–30 minutes depending on traffic. Ride‑share apps like Pathao and Tootle are available and cost slightly less. Public buses run but are crowded, slower, and less reliable. Hotel shuttles offer convenience at a moderate price. Driving and parking at the airport is possible but uncommon due to limited space."
