        "question": "What is the typical flight duration from Denver to Kathmandu?",
        "answer": "There are no nonstop flights from Denver (DEN) to Kathmandu (KTM). A typical itinerary with one stop, often via Istanbul, Doha, or Dubai, takes around 20 to 24 hours of total flight time, plus layover time. The return flight is similar in duration."
      },
      "q1": {
        "question": "Are there any direct flights from Denver to Kathmandu?",
        "answer": "There are no nonstop flights from Denver to Kathmandu — every itinerary requires at least two stops. The shortest connecting routing found takes about 23 hours and 55 minutes, operated by United with two connections. Fares for these multi-stop journeys start around $728 round-trip on JetBlue, though United offers the quickest option at roughly $6,341.",
        "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. Quoted prices come from real-time, bookable flight offers from our airline partners. Prices are dynamic and subject to change throughout the day.",

        "question": "Are there visa requirements to travel from Denver to Kathmandu?",
        "answer": "Yes. 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."
      },
      "q4": {
        "question": "When is the cheapest time to fly from Denver to Kathmandu?",
        "answer": "The cheapest months to fly from Denver to Kathmandu are January, February, and April, with average fares around $1,600–$1,660. The most expensive months are June, December, and July, where average prices climb above $1,960, peaking at about $2,100 in June.",
        "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.",

      "q5": {
        "question": "How far in advance should I book tickets from Denver to Kathmandu?",
        "answer": "For flights from Denver to Kathmandu, the optimal booking window is about 8 to 11 weeks before departure, with average fares around $1,693. The cheapest single day to book is around 55 days out at roughly $1,673, while last-minute bookings (0–5 days prior) can cost $2,000 or more. During summer and holiday periods, you should book a few weeks earlier than the typical window to secure the best fare, as demand can push prices higher.",
        "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.",

        "answer": "No overnight (red-eye) flights are available from Denver to Kathmandu — neither nonstop nor connecting itineraries with a red-eye long leg operate on this route.",
        "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 Denver to Kathmandu. The route is typically served by connecting itineraries, though the data does not provide specific carrier or fare details for these multi-stop routings.",
        "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).

        "question": "If I need a connection, what are common layover cities between Denver and Kathmandu?",
        "answer": "Common layover hubs for the Denver to Kathmandu route include Doha, Dubai, and Istanbul. These cities offer broad connections and efficient transfers, with Doha and Dubai providing visa-free transit for many nationalities, while Istanbul serves as a strategic bridge between the Americas and Asia, minimizing total travel time."
      },
      "q9": {
        "question": "How reliable are on‑time departures on this route from Denver to Kathmandu?",
        "answer": "On-time performance is variable due to multiple connections and weather risks. Early departures from Denver and choosing carriers like Qatar Airways or Turkish Airlines with strong hub efficiency can improve your odds."
      },
      "q10": {
        "question": "Which months have the best weather for traveling to Kathmandu?",
        "answer": "October and November offer clear skies, mild temperatures, and fewer tourists than spring."

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

      },
      "q12": {
        "question": "Which airport should I use in Kathmandu?",
        "answer": "Kathmandu has only one airport, Tribhuvan International Airport, which serves all domestic and international flights and is about 6 km from the city centre."
      },
      "q13": {
        "question": "How do I get to Denver Intl Airport from the city center?",
        "answer": "From downtown Denver, the A-Line commuter train is the fastest and most popular option, reaching the airport in about 37 minutes from Union Station for around $10.50. Ride-share services like Uber and Lyft offer door-to-door convenience with typical fares ranging from $40 to $60, while taxis charge a flat rate of approximately $56 from downtown. Several shared shuttle services and public buses also serve the airport, and driving yourself is possible with on-site parking available, though costs vary by lot.",
