AD PLACEMENT — CONTEXTUAL
Always check whether your connection is within Terminal 3 or requires a transfer to/from Terminal 2, as the latter needs much more buffer time.
All connecting passengers, including domestic-to-domestic, must clear security again — carry-on liquids and electronics rules are strictly enforced.
International arrivals connecting to another international flight still route through immigration-adjacent transfer desks in some cases, so confirm with your airline whether a true transit-without-visa corridor applies.
Take advantage of Beijing's 144-hour visa-free transit policy if you have a long layover and want to leave the airport, but this requires pre-planning and is not useful for short connections.
Signage is bilingual (Chinese/English) but the terminal is enormous, so budget extra walking time even after clearing security.

Low risk
Moderate
High risk
Tight connections are safer outside peak hours. Morning rush (6–9a), midday (11a–2p), and evening (4–8p) are highest risk.
Within Terminal 3, an automated people mover (APM) links the 3C/3D domestic/Star Alliance zone with the international 3E concourse in about 5–8 minutes, though queuing for the connected security and immigration checks adds significant time. Moving between Terminal 2 and Terminal 3 requires a free inter-terminal shuttle bus (15–20 minutes) plus a fresh security screening on arrival, as there is no landside walkway between them.
