        "question": "What is the typical flight duration from Kathmandu to San Francisco?",
        "answer": "There are no nonstop flights from Kathmandu (KTM) to San Francisco (SFO). A typical one-stop itinerary, often via Doha, Dubai, or Istanbul, takes around 20 to 24 hours total travel time. The return flight from San Francisco to Kathmandu is similar in duration."
      },
      "q1": {
        "question": "Are there any direct flights from Kathmandu to San Francisco?",
        "answer": "There are no nonstop flights from Kathmandu (KTM) to San Francisco (SFO). The shortest connecting itineraries are one-stop and typically take around 30 hours and 50 minutes, with airlines like Cathay Pacific, Turkish Airlines, China Southern, and Emirates offering these routings via hubs such as Hong Kong, Istanbul, or Dubai. Fares for one-stop connections start around $1,200, with typical prices near $1,850.",
        "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. 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.",

        "answer": "Yes, visa requirements apply when traveling from Kathmandu to San Francisco. U.S. citizens do not need a visa to enter Nepal but must obtain a visa on arrival or in advance for Nepal. For the flight from Kathmandu to San Francisco, Nepalese citizens require a U.S. visa unless eligible for the Visa Waiver Program (which they typically are not). Travelers of other nationalities must check both Nepalese exit requirements and U.S. entry requirements based on their citizenship."

        "question": "What are the ground transportation options in San Francisco?",
        "answer": "From SFO, BART rapid rail is the fastest and most-used option to downtown San Francisco, with a station in the International Terminal connected to all terminals by AirTrain. Ride-share services like Lyft and Uber pick up on Level 5 of the Domestic Garage, while taxis are available at the center islands outside of Arrivals. Rental cars are accessible via the AirTrain Blue Line to the consolidated Rental Car Center. Waymo autonomous rides are also available for select passengers at the Rental Car Center. Hotel shuttles and SamTrans buses provide additional public transit alternatives.",

        "question": "When is the cheapest time to fly from Kathmandu to San Francisco?",
        "answer": "The cheapest months to fly from Kathmandu to San Francisco are September, April, and August, with average fares around $1,325–$1,370. The most expensive months are June, December, and July, where average fares range from $1,660 to $1,821.",
        "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 San Francisco?",
        "answer": "For the best fare from Kathmandu to San Francisco, aim to book 9–12 weeks ahead, when prices average around $1,443. Booking about 75 days out can yield the lowest fares (around $1,426), while last-minute tickets cost significantly more, often exceeding $2,000. This optimal window may shift slightly for summer or holiday periods, when demand can push the best booking time a bit earlier.",
        "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 San Francisco. Neither nonstop red-eyes 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.",

The most frequent one-stop options are operated by Air India via Delhi (around 4 daily connections) and Emirates via Dubai (also about 4 daily), with Cathay Pacific via Hong Kong offering roughly 2 daily connections. Other carriers serving the route include Qatar Airways via Doha and China Southern via Guangzhou, each with about 1 daily connection.

      },
      "q9": {
        "question": "How reliable are on‑time departures on this route from Kathmandu to San Francisco?",
        "answer": "On-time performance can be inconsistent due to weather and operational challenges at Kathmandu. Early flights are your best bet, particularly on airlines like Qatar Airways or Emirates, which have stronger punctuality records."

      },
      "q12": {
        "question": "Which airport should I use in San Francisco?",
        "answer": "San Francisco International is the main airport, located 13 miles south of downtown. It serves as a hub for United Airlines and offers extensive international and domestic connections. Oakland International, across the bay, is a focus city for Southwest Airlines and handles many low‑cost and domestic flights. San Jose International, about 45 miles south of San Francisco, is convenient for Silicon Valley and serves a mix of domestic and limited international routes."
      },
      "q13": {
        "question": "How do I get to Tribhuvan Intl Airport from the city center?",
        "answer": "From central Kathmandu, the most popular way to reach Tribhuvan International Airport is by pre-paid taxi or ride‑share, which takes about 20–30 minutes in typical traffic and costs relatively more than public options. Local buses and tourist shuttle services also connect the city center to the airport at a lower cost, though they can be slower and less frequent. Driving yourself is possible but parking is limited, so most visitors rely on taxis or hotel‑arranged transfers for convenience.",
