How early should I get to CUN?
Cancún International Airport, Cancún, Mexico · Checked Oct 25, 2026
The short answer
When you're traveling outside of the United States, we suggest arriving at least 3 hours prior to your departure. (Delta; JetBlue and Southwest also advise 3 hours at Cancún.)
Those are blanket rules. Your real number depends on your terminal, the time of day, passport control and whether you're checking a bag. Leave By works out your exact leave time.

Passport control on the way out
Mexico has no separate exit immigration check for departing tourists; your airline checks your passport at check-in. Air arrivals no longer fill in a paper FMM tourist card: you get a passport stamp or an e-gate ticket, and the digital record (FMMd) can be downloaded from Mexico's immigration institute (INM). Keep your passport with its entry stamp and any printed e-gate ticket; UK government advice tells visitors they must show these when leaving. Quintana Roo's Visitax tourist tax applies to all foreign tourists, and spot checks just before security were reported in December 2025, so keep your Visitax QR code handy. Cancún has no US preclearance, so you clear US immigration and customs after you land.
