So How early to arrive to the Cancun International Airport for your international flight?
The quick answer is that you should arrive 3 hours prior to your flight at the Cancun Airport.
The Cancun Airport states that you have to show up 3 hours prior for international flights. We and lots of people say that 2 Hours is enough, but this will always depend on the season of the year, the amount of luggage you have and the number of people in your party. Remember that at Cancun Airport Transportation we suggest these times, however you can decide your own at the moment of reserving.
