Cancún International Airport (CUN)

Cancún International spreads passengers across four terminals: Terminal 1 for seasonal/charter operations, Terminal 2 with two concourses (H for domestic/regional and M for international), Terminal 3 focused on U.S. and European carriers, and the modern Terminal 4 handling both domestic and long-haul international flights. Each terminal has separate check-in halls and security, and bus gates at Terminal 2 and 3 are common for regional routes. A free inter-terminal shuttle stops outside each arrivals curb every 10–15 minutes; the ride between the most distant terminals takes about 15–20 minutes, so allow extra time when changing buildings. Within a terminal, walks are manageable: 5–10 minutes from security to most gates in Terminals 2 and 3, while Terminal 4’s A/B concourses can take up to 15 minutes with some stairs or elevators down to bus positions. Landside transfers between terminals are also possible by taxi, but airside transfers are not available—every change of terminal requires exiting and re-screening. Security checkpoint waits average 10–20 minutes outside of holiday peaks, though midday departures to the U.S. can push queues toward 30–40 minutes; priority and family lanes are signed at each terminal. Non-Mexican travelers typically complete immigration on arrival before baggage claim, and customs still uses the red/green light system for random inspections; agricultural items and large electronics may be pulled for additional screening. Amenities vary by terminal: duty-free corridors and cafés line the departures levels, with Mera Business Lounges in Terminals 2, 3, and 4 plus a Plaza Premium Lounge and The Lounge by Global Lounge Network in Terminal 4. Terminal 3 and 4 have larger food courts and brand-name shops, while Terminal 2 offers convenience dining and currency exchange near the H gates. Free Wi‑Fi is available in Terminals 3 and 4, with paid options more common in Terminal 2. All terminals provide ramps, elevators, and wheelchair assistance on request, and the inter-terminal shuttle accommodates passengers with reduced mobility. Baby-care and nursing rooms are signed near several gates in Terminals 3 and 4, and small children’s play areas sit near the B concourse in Terminal 4; family restrooms and changing tables are distributed throughout arrivals and departures areas.
