        "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). With one stop, the total travel time typically ranges from 18 to 22 hours, depending on the layover location and duration. Common layover cities include Doha, Dubai, and Istanbul.

        "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 one-stop connections typically route via Dubai (DXB) on flydubai and Emirates, with the first leg around 4.5 hours and the second leg about 16.5 hours, plus a layover of roughly 5 hours, making total travel time around 26 hours. Other common one-stop options go via Delhi (DEL) on Air India or via Hong Kong (HKG) on Cathay Pacific, with similar or longer total durations.",
        "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).

        "question": "What are the ground transportation options in San Francisco?",
        "answer": "From San Francisco International Airport (SFO) to the city center, the Bay Area Rapid Transit (BART) system is the most used option, reaching downtown in about thirty minutes. It is efficient, affordable, and avoids traffic. SamTrans buses also serve the airport but are slower and less direct. Taxis and ride-share services like Uber and Lyft are widely available, offering door-to-door convenience, though travel times vary from twenty-five to forty-five minutes depending on traffic and they are more expensive. Car rentals are available at SFO but are generally not recommended for city exploration due to limited and costly parking. The BART train is the most popular choice for its speed, reliability, and value."

        "answer": "The cheapest months to fly from Kathmandu to San Francisco are September (average $1301), January ($1306), and August ($1310), while the most expensive are June ($1828), December ($1670), and July ($1604).",
        "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.",

        "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.",
