AD PLACEMENT — CONTEXTUAL
Check whether your connection stays within the Main Terminal or requires a klia2 transfer, as the latter can eat well over an hour.
If transferring between Main Terminal and klia2, budget at least 2 hours since you must clear security again and possibly immigration.
Use the free inter-terminal shuttle bus rather than waiting for the KLIA Ekspres if your layover is tight, as buses run more frequently for transfer passengers.
Malaysia Airlines and oneworld connections within the Main Terminal via the Aerotrain are fast and don't require re-screening.
AirAsia's self-transfer product often books tight connections at klia2, so don't assume airline ticketing guarantees a comfortable buffer.

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 the Main Terminal, the automated Aerotrain shuttles passengers to the Satellite Building in about 2-3 minutes with no re-screening for onward connecting flights. Moving between Main Terminal and klia2 requires either a free inter-terminal shuttle bus (roughly 20 minutes) or the KLIA Ekspres train (about 3 minutes of ride time), but in both cases you exit and re-enter secured areas, meaning a full security screening and sometimes immigration/customs re-clearance.

If you miss a connection, Malaysia Airlines and other full-service carriers have transfer desks in the Main Terminal arrivals/transit area, while AirAsia passengers should go to the AirAsia service counters in klia2; both can rebook you onto the next available flight, though LCC rebooking often carries a fee.
