        "answer": "There are no nonstop flights from Washington (IAD) to Kathmandu (KTM). With one stop, the fastest total travel time is around 18 to 19 hours, typically via Doha or Dubai; with two stops, total time often exceeds 22 hours. The return flight duration is similar, though it can vary slightly depending on layover length and routing."

      "q1": {
        "question": "Are there any direct flights from Washington to Kathmandu?",
        "answer": "There are no nonstop flights from Washington Dulles (IAD) to Kathmandu (KTM). The shortest connecting routing is a one-stop itinerary, most commonly via Doha (DOH) on Qatar Airways, taking around 27 hours total with a short layover. Emirates via Dubai (DXB) and Etihad via Abu Dhabi (AUH) are also one-stop options, with typical fares starting around $1,300–$1,350 and median prices in the $1,750–$1,900 range.",
        "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.

        "answer": "Yes, visa requirements apply for travel between Washington, D.C. (IAD) and Kathmandu (KTM). U.S. citizens need a visa to enter Nepal, obtainable on arrival at Kathmandu airport or in advance from a Nepalese embassy. Nepalese citizens require a visa to enter the United States, which must be obtained from a U.S. embassy or consulate before travel. Travelers of other nationalities should check both U.S. and Nepalese entry requirements based on their citizenship."

      "q3": {
        "question": "What are the ground transportation options in Kathmandu?",
        "answer": "From Tribhuvan International Airport (KTM) to central Kathmandu, prepaid taxis are the most reliable and widely used option, with a fixed fare counter inside the terminal ensuring a set price. Metered taxis are also available outside, but agreeing on a fare beforehand is common. Ride-hailing apps like Pathao and Tootle operate in the city, though pickup at the airport can be inconsistent. Public buses run from the airport gate to Ratna Park and other city points, but they are often crowded and not recommended with luggage. There is no rail or mass transit link, and self-drive car rental is virtually nonexistent; a pre-arranged hotel pickup is the most convenient choice.",

        "question": "When is the cheapest time to fly from Washington to Kathmandu?",
        "answer": "The cheapest time to fly from Washington to Kathmandu is late summer and early fall, with August averaging $1,457, September $1,476, and April $1,527. The most expensive months are December at $2,028, June at $2,002, and July at $1,823.",
        "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.",

        "question": "How far in advance should I book tickets from Washington to Kathmandu?",
        "answer": "For the best fare from Washington to Kathmandu, aim to book 6 to 9 weeks before departure, when average prices hover around $1,640. The absolute cheapest window is about 50 days out, at roughly $1,633, while last-minute bookings can spike above $2,000. Summer and holiday periods typically push the ideal booking window earlier, so consider locking in tickets 10 to 12 weeks ahead for peak 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.",

        "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": "No airline flies nonstop from Washington Dulles to Kathmandu. The most common one-stop connection is on Qatar Airways via Doha, with about 11 daily options. Emirates also offers a handful of routings through Dubai, sometimes with a second leg on flydubai or Nepal Airlines. Etihad provides a single daily connection via Abu Dhabi, with the onward segment operated by Air Arabia Abu Dhabi.",

Doha and Dubai offer efficient one-stop connections via Qatar Airways and Emirates, with visa-free transit for many nationalities. Istanbul provides a geographic midpoint with Turkish Airlines' broad network, and Delhi serves as a gateway with connections on airlines like Air India, though a transit visa may be required for some travelers."

        "question": "Which months have the best weather for traveling to Kathmandu?",

      },
      "q13": {
        "question": "How do I get to Washington Intl Airport from the city center?",
        "answer": "From downtown Washington, D.C., the fastest public transit option to Dulles is taking the Metrorail Silver Line directly to the airport station. A cheaper alternative is the Silver Line Express bus, which runs nonstop from the Wiehle-Reston East station to the terminal and costs $5 each way. Ride-share services like Uber and Lyft are authorized and offer door-to-door convenience, while Washington Flyer taxis are available 24/7 at the terminal. Driving and parking is also an option, with economy lots starting at $15 per day and a free shuttle to the terminal.",
