AD PLACEMENT — CONTEXTUAL
If arriving internationally, budget extra time for immigration and baggage reclaim before rechecking for a domestic flight.
Confirm which terminal your connecting flight departs from, as Hainan Airlines and China Southern flights can be split between T1 and T2.
Use the inter-terminal shuttle rather than walking if you have less than 45 minutes, as the walkway route can be longer than it looks on paper.
Domestic-to-domestic connections on the same terminal are the easiest; avoid tight connections requiring a terminal change during peak morning or evening banks.
Chinese ID/passport checks at security can be slow for foreign passport holders, so allow extra buffer time versus locals with ID cards.

High risk
Tight connections are safer outside peak hours. Morning rush (6–9a), midday (11a–2p), and evening (4–8p) are highest risk.
Terminal 1 and Terminal 2 are linked by a covered walkway and shuttle bus service, with the walk itself taking 10-15 minutes plus queuing for security. International arrivals must clear immigration and customs before any onward connection, even to a domestic flight, since there is no dedicated international-to-domestic transit corridor.
