CUN City Code: Cancun IATA Airports
CUN identifies the city of Cancun, Mexico, in IATA coding. Airport codes in this dataset for that city: CUN. A city code is not always the same as an airport code.
Overview
CUN is the IATA city code stored for Cancun, Mexico (MX). City codes group one or more airports. In this dataset CUN is aligned with airport CUN. Some cities share the airport code; others (NYC, LON, TYO) do not. Airport names stored: CUN Cancún International Airport. GDS availability and some pricing entries use the city code when the traveller can use any airport in the metro. Ticketed segments still print a specific airport such as JFK rather than NYC. This page does not list every airfield in the metropolitan area, only rows in the catalog. Timezone and ICAO live on each airport page.
How to use this page
- Search CUN or Cancun in the city code finder.
- Open each airport page for ICAO and timezone.
- Parse the actual PNR to see which airport was ticketed.
Example
