AD PLACEMENT — CONTEXTUAL
Assume you will have to reclaim bags, clear customs, and recheck in for any international arrival with a connection — CUN has no true sterile transit zone for most itineraries.
If your connection spans terminals, budget extra time for the inter-terminal shuttle bus, which can be slow during midday charter surges.
Book connections on a single ticket with the same airline or alliance where possible, since CUN ground staff can be scarce for rebooking walk-in passengers.
Aeromexico's domestic-to-domestic connections within Terminal 2 are the smoothest option if you must connect here.
Arrive at your gate well before boarding closes, since gate changes and long walks in Terminal 3's international wing are common.

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.
Terminal 2, 3, and 4 are separate structures connected by a free inter-terminal shuttle bus that runs every 10-20 minutes, with the T2-to-T4 leg taking the longest. There is no airside train or sterile walkway between terminals, so passengers connecting across terminals must exit, take the bus, and re-enter through security (and often immigration) at the new terminal.
