Airport
Cancún International Airport (CUN)
Cancún is the busiest way into the Caribbean side of the country, and it behaves less like one airport than like several parked side by side: the terminals are separate buildings, allocated by airline rather than by domestic or international, and nothing joins them airside. The flight is rarely the hard part. The hard part is the short walk between customs and the doors, where the airport's commercial ecosystem waits for tired arrivals — and knowing in advance who may actually drive you into Cancún or down the coast.

Four terminals, allocated by airline
The buildings are numbered but not specialised: the main three each handle a mix of domestic and international departures, and which one your airline uses is a commercial arrangement that shifts between seasons. Check the terminal on the boarding pass on the day of travel rather than trusting a guidebook, a friend, or a memory of last winter's trip.
A free airport bus circulates between the terminals and is the only no-cost way to move between them. It is a landside service, so a self-connection means collecting bags, leaving the building and clearing security again in the next one. Two separately booked flights through Cancún therefore need genuine time between them, not the turnaround a single airline would sell you.
Getting out of arrivals
Past customs the corridor is lined with counters that look like information desks, transport desks or tourist offices and are mostly selling holiday-club presentations dressed up as a free transfer or a discounted tour. The tell is simple: nobody with a legitimate reason to speak to you stands between customs and the exit doors. Keep walking, agree to nothing, and hand over neither passport nor hotel reservation.
Prebooked drivers wait outside the terminal, not inside it, and hold a name board at the kerb. If you have booked a transfer, its instructions will send you out of the building — follow them literally rather than accepting help halfway along the corridor.
Coaches, the train shuttle and who may collect you
Coach stops sit directly outside the terminals with ticket counters inside, and the services run both to the city's own bus station and straight down the highway to the beach towns of the Riviera Maya. This is how most independent travellers leave. Fares are modest and popular departures do sell out, so buying only on arrival can mean waiting for the one after.
A railway station serves the airport but is not walkable from it: shuttle buses timed to the Tren Maya departures leave from each terminal and are sold at the same counter. Authorised airport taxis work to posted zone fares. Ride-hailing apps cannot pick up at the terminals at all, and a driver who agrees to try will usually cancel on arrival.
The border, the waves and the day of the week
Immigration records the stay as a stamp with the permitted days written beside it. There is no paper card to keep and none to surrender on the way out, which catches out returning visitors who remember the old routine, so read what the officer has written before leaving the hall. What a passport needs before boarding is a matter for the entry rules for Mexico.
The airport's rhythm is the resort calendar rather than the working week. Saturdays and Sundays are when whole hotel weeks turn over, and both the arrivals hall and departure security stretch accordingly, while a midweek flight clears in a fraction of the time. For a weekend departure, arrive far earlier than the flight time alone suggests.
Onward: a hire car, the ferry ports, the domestic wing
Hire-car companies keep small modules at baggage claim and their lots off-site, a shuttle ride away. The trap here is insurance: Mexican law requires local third-party liability cover, many online quotes exclude it, and the counter then adds it at a price that can exceed the rental itself. Get written confirmation of what your booking includes before you fly.
Ferries to the islands leave from ports along the coast rather than from the airport, reached by the same coaches or by road, and the cenote and reef country inland is the other direction people take from here. Domestic flights also link the peninsula to the rest of the country without routing through the capital.
Layovers, late landings and the practical end
A hotel strip lines the airport road with its own shuttles, and it exists for two situations: a pre-dawn departure, and a landing late enough that driving an unfamiliar highway in the dark is the worse option. That decision is much cheaper made at the booking stage than at the kerb at midnight.
Two habits save money and friction. Prices along the resort strip are often quoted in US dollars, and paying that way costs you the spread twice over, so ask for the figure in pesos and settle in them where you can. The other is data: transfer, booking and map all live on a phone, and a connection that works the moment you land is worth arranging before departure.
