AD PLACEMENT — CONTEXTUAL
If your connection spans T3 and T4, budget extra time for the inter-terminal shuttle, which can have long waits during peak hours.
International arrivals must clear immigration and collect checked bags before rechecking in for any onward flight, even domestic ones.
Xiamen Airlines same-terminal domestic connections are the smoothest option here and can be made in under an hour if both flights are in T3.
Signage is bilingual (Chinese/English) but staff English proficiency is limited, so have your boarding pass and connection details printed or ready to show.
Avoid tight connections around the 7-9am and 6-8pm banks, when Xiamen Airlines' domestic schedule peaks and queues lengthen.

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.
T3 handles the bulk of domestic and all international flights, while T4 is a secondary domestic terminal used mainly by Xiamen Airlines for overflow routes; a free shuttle bus connects the two, taking about 10-15 minutes plus waiting time. Passengers connecting between international and domestic flights must exit through immigration/customs, collect and recheck bags, and pass back through security, as there is no dedicated airside international transit corridor.
