Who This Helps

  • Foreign visitors flying between Chinese cities.
  • Travelers comparing high-speed rail and domestic flights.
  • Travelers carrying passports, power banks, or checked luggage.

Before You Start

  • Enter passport details exactly when booking.
  • Carry the original passport and any visa or entry documents.
  • Arrive earlier than a local frequent flyer, especially at unfamiliar airports.
  • Check airline baggage and battery rules before packing.
  • Keep power banks in carry-on and review current CCC marking rules for domestic flights.
  • Store hotel address in Chinese for arrival transfer.
  • Compare domestic flight door-to-door time against high-speed rail before choosing.

Common Failure Cases

  • The ticket name does not match passport order. Contact the booking platform or airline before airport arrival.
  • A domestic flight looks faster than rail. Compare door-to-door time.
  • The official source and a platform or staff answer do not match. Follow the more authoritative official or on-site source, keep screenshots or documents, and choose the lower-risk fallback until the conflict is resolved.

Source cross-check

This answer was checked against CAAC: power banks without CCC markings prohibited on domestic flights and China Eastern Airlines: safety instructions for lithium batteries and dangerous goods. A third source, U.S. Department of State: China travel advisory and country information, was used where the answer depends on implementation detail or traveler-facing handling. Additional support from China Southern Airlines: domestic passenger check-in with valid ID documents was kept when official rules and platform execution need to be separated. Where sources use different scope or dates, the guide follows the current official or most directly authoritative source and keeps platform or traveler-facing material as implementation context only.
