        "question": "Which cities in China can I fly to from San Francisco?",
        "answer": "From San Francisco you can fly non-stop to Beijing and Shanghai. One-stop connections via those hubs or Guangzhou, Chengdu, and Hong Kong open up most of China. Beijing is best for history and the Great Wall, while Shanghai serves as a modern gateway with high-speed trains to nearby cities."

        "question": "When is the cheapest time to fly from San Francisco to China?",
        "answer": "The cheapest months to fly from San Francisco to China are September through November, with late summer (August) also offering lower fares, while peak summer (June–July) and the December holiday season are the most expensive. Booking about 23 to 26 weeks ahead tends to yield the best prices, and though specific day-of-week data isn't available for this route, midweek departures (Tuesday/Wednesday) and off-peak times like early morning or late evening typically cost less than weekend and midday flights. Peak summer and major holidays such as Chinese New Year and Christmas drive prices significantly higher.",
        "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. 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."

        "question": "How far in advance should I book flights from San Francisco to China?",

        "question": "Do I need a visa to travel from San Francisco to China?",
        "answer": "U.S. citizens traveling from San Francisco to China for tourism must obtain a visa before departure, as visa-free entry is not available for American tourists. China does not currently offer an electronic travel authorization for U.S. citizens, and visa requirements can change, so check with the Chinese embassy or consulate before your trip."

        "question": "Which airports in China are best to fly into from San Francisco?",
        "answer": "From San Francisco to China, Beijing Capital, Shanghai Pudong, and Guangzhou Baiyun offer direct flights and extensive onward connections. Beijing and Shanghai are ideal for high-speed trains to major cities, while Guangzhou works well for southern China and regional travel."

      "q12": {
        "question": "When is the best time of year to visit China?",
        "answer": "April to May and September to October are ideal for China, with comfortable weather and fewer tourists than the summer peak. Summer is hot, crowded and pricier, especially in Beijing and Shanghai."
