How far in advance should I book plane tickets, hotels, and popular attractions?

International Flights: Most cost-effective if booked 2–3 months in advance; Lunar New Year and summer holidays require booking 4–6 months ahead. Domestic Flights: Book 30–60 days in advance, commonly available at 30–60% of the full price; during Spring Festival travel season and National Day, buy as soon as tickets are released. High-Speed Rail: Advance booking period is 15 days (30 days for some), popular routes sell out instantly, use waiting list feature. Hotels: On weekdays, book 2–4 weeks ahead; during peak season (National Day, Lunar New Year, summer holidays) book 1–2 months in advance, prices may double. Popular Attractions: Forbidden City 7 days in advance (tickets released daily at 20:00), Jiuzhaigou 14 days in advance, Mogao Caves 30 days in advance (A-class tickets in peak season sell out the same day). Tibet Entry Permit: At least 15–20 working days in advance, recommended to start a month ahead. In short: Book flights and Tibet entry permits first, attractions according to their ticket release schedules, and hotels in between.
