The airports are about 7,580 miles apart, and a typical one-stop itinerary takes roughly 20 to 24 hours of total travel time, depending on the layover.", "methodology": "Carrier service, flight times and distances for this route come 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). We report the days of the week and the departure times each carrier operates. The typical flight time is the median scheduled block time, given both per carrier and across all carriers on the route; where a schedule does not publish an elapsed time, it is derived from the scheduled departure and arrival times converted to UTC. Outbound and return times are computed by the same method, so the difference between them is directly comparable and reflects prevailing winds rather than any change in derivation. Distance is the great-circle distance between the two specific airports named, so an actual flown track is typically 2-5% longer. Where shown, on-time departure and arrival rates and cancellation rates come from the U.S. Bureau of Transportation Statistics (BTS) Airline On-Time Performance dataset, which covers U.S. domestic routes only; where a typical fare is shown, it comes from the U.S. DOT Airline Origin and Destination Survey (DB1B), a quarterly 10% sample of tickets sold.", "toolsUsed": ["flight_schedule"]}, "q1": {"question": "Are there any direct flights from Kathmandu to San Francisco?", "answer": "There are no nonstop flights from Kathmandu to San Francisco.

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.

Ride-share services like Uber and Lyft pick up on Level 5 of the Domestic Garage, while taxis are available outside arrivals. Rental cars are centralized at the Rental Car Center, accessible via the AirTrain Blue Line, and many hotels offer complimentary shuttles.

The most expensive months are June, December, and July, where average fares climb to approximately $1,821, $1,758, and $1,653. August and the low-season months also offer lower prices, while November and the high-season months see higher costs.", "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.", "toolsUsed": ["seasonal_prices"]}, "q5": {"question": "How far in advance should I book tickets from Kathmandu to San Francisco?", "answer": "For the best fare on flights from Kathmandu to San Francisco, aim to book around 9 to 12 weeks ahead, when average prices are lowest at about $1,449. The absolute cheapest point is roughly 75 days before departure at around $1,432, while waiting until the last minute pushes fares above $2,000. Summer and holiday periods typically require booking even earlier, as demand drives prices up and the optimal window may shift to 12–16 weeks out.", "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.
