Airport hub guide
Cancun International CUN: the complete layover guide
Mexico's busiest holiday gateway runs three working terminals with no airside link between them and an immigration hall that can swallow an hour of your life. Here is how to handle a Cancun layover without losing your nerve.
Layover verdict Fine for 2 to 4 hours spent inside one terminal, hard work for anything that involves changing buildings, because every transfer happens landside and every international arrival clears immigration first.
Best lounge play The Lounge in Terminal 3 takes Priority Pass for international departures with a 4 hour stay cap. The Mera Business Lounges in T2, T3 and T4 cover the rest, with entry rules that vary by card.
The one thing to know There is no sterile transit at CUN. Connecting passengers clear Mexican immigration and customs like everyone else, and at peak holiday banks that hall can run well past an hour.

Orientation
How Cancun is laid out
Cancun is a point to point charter and leisure airport wearing a hub's traffic numbers: three working terminals strung along an access road south of the city, each one a separate island once you are inside.
Terminal 2 is the domestic heart and takes Aeromexico, Volaris and a mix of international services. Terminal 3 handles most of the big US carriers, including American, Delta and United. Terminal 4 hosts Southwest, JetBlue and long haul Europeans such as Lufthansa and Air France. Assignments shift, so check your airline on the day. Terminal 1, the old charter building, is closed to scheduled flights; a rebuild is reported to bring it back around mid 2026 ahead of the World Cup, timing to be confirmed.
The transfer math is the part that surprises people. There is no airside connection between any terminals at CUN. Changing buildings means walking out, finding the marked shuttle stop on the curb, and riding a free bus that loops T2, T3 and T4 around the clock. Published frequencies vary, so plan on a wait of up to 30 minutes, then a full security screening at the next terminal. The shuttle costs nothing. Anyone offering to sell you that ride is running a hustle.
Immigration is the other tax on your time. Every international arrival clears Mexican immigration and customs, connections included. The paper FMM tourist card has been eliminated for air arrivals at Cancun; the visitor permit is now issued digitally at the booth. That speeds up the paperwork but not the line. When several widebodies land together in high season, the hall can take well over an hour.
Leaving the airport is cheap if you take the bus. ADO coaches run from outside Terminals 2, 3 and 4 to the downtown bus station on Avenida Uxmal for 140 pesos, about 7 US dollars, taking 25 to 40 minutes, with departures every 30 to 60 minutes. The ADO route does not serve the Hotel Zone directly; from downtown you continue by local bus or taxi. Prebooked private shuttles run to the Hotel Zone from about 29 dollars per vehicle. Book transport before you exit, or walk straight to the ADO counter.
Timing honesty: on a single ticket connecting through CUN, treat 2.5 to 3 hours as the floor once you count immigration, customs, the landside shuttle and a second security screening. On separate tickets, give it 4 hours. People do make shorter connections here. They tend to be the ones who landed at 7am in low season.
Terminal by terminal
What each terminal gives you
Terminal 1
Closed to scheduled passenger flights. The original charter building has been out of regular service for years; a rebuild is reported, with reopening planned around mid 2026 as part of the World Cup expansion. Until the airport confirms a date, plan around T2, T3 and T4 only.
Terminal 2
The domestic workhorse, with Aeromexico and Volaris running the show alongside some international services. It feels the most dated of the three, but it holds one quiet advantage for the stranded: a few short benches without armrests. Airside, a Mera Business Lounge sits on the upper floor past the duty free shops. ADO buses to downtown leave from directly outside.
Terminal 3
Built for the US market, which means American, Delta and United. For independent lounge access this is the strongest terminal at CUN: The Lounge sits on the upper floor next to Gate C17, takes Priority Pass for international departures, and caps stays at 4 hours. A Mera Business Lounge operates here as well. If you hold Priority Pass and have any say over where you wait, wait in T3.
Terminal 4
The newest and most comfortable building, serving Southwest, JetBlue, Lufthansa and Air France. Mera runs two lounges here, one for international departures near Gate 67 and a separate domestic lounge. Traveler guides report sleep pods inside the Mera operation at T4; confirm directly before building an overnight around them. Of the three working terminals, this is the one where killing 5 hours hurts least.

FAQ
Cancun layover questions
Can I sleep overnight at Cancun airport?
The terminals stay open 24 hours, so you can, but it is a rough night: most seating has armrests, the air conditioning runs cold, and there are no free rest zones. T2 has a few short benches without armrests. The Yellow Capsule pod hotel just off airport is the better play; its 24 hour shuttle runs at an extra charge.
How do I transfer between terminals at CUN?
There is no airside link, so you exit the terminal and take the free shuttle bus that loops T2, T3 and T4 around the clock. Budget up to 30 minutes for the wait and ride, then a full security screening at the next building. The shuttle is free; never pay anyone for a transfer between terminals.
Do I clear immigration on a connection at Cancun?
Yes. Cancun has no sterile transit, so every international arrival clears Mexican immigration and customs, connecting or not. The paper FMM tourist card has been eliminated for air arrivals and the visitor permit is now issued digitally at the booth.
Is wifi free at Cancun airport?
Yes, but with a catch: free sponsored sessions are capped at 60 minutes and travelers regularly report patchy connectivity at busy times. For a long layover, bring an eSIM or local data rather than relying on the airport network.
Can I leave the airport and hit the beach during a layover at CUN?
With about 6 hours or more, yes. ADO buses run to downtown Cancun in 25 to 40 minutes for 140 pesos, and prebooked shuttles reach the Hotel Zone beaches from about 29 dollars per vehicle. You will clear immigration and customs both ways, and Mexican entry rules depend on your nationality; verify before travel.
Which lounges at CUN take Priority Pass?
The Lounge in Terminal 3 takes Priority Pass for international departures, with a 4 hour stay cap and a boarding pass check. The Mera Business Lounges in T2, T3 and T4 are listed by several access programs, but traveler reports on acceptance are mixed, so confirm your specific card in the app on the day.

The country's true connecting hub. If you can route a domestic connection through MEX instead, the transfer is usually less painful.

The US hub on many Cancun itineraries, with far deeper lounge coverage and proper airside links between concourses. A different layover league entirely.
Guadalajara (GDL)
Mexico's second city airport and a growing low cost base. Smaller and simpler than CUN, with a fraction of the immigration queue drama.
