Overview

CUN is the IATA airport code stored in this dataset for Cancún International Airport in Cancun, Mexico (MX). The matching ICAO identifier is MMUN. Travel agents see CUN on tickets, baggage tags, and GDS segment city pairs (six letters, for example CUNLHR when the other airport is London Heathrow). ICAO MMUN is used in flight plans and ATC, not as the two-or-three-character GDS city-pair token. The IANA timezone recorded for local GDS times at this airport is America/Cancun. This code page explains how CUN is used in PNR text. It is not a live departures board. Terminal maps, contact phone numbers, lounge lists, and published flight schedules are not available in this dataset and are not invented here. Nearby airports stored for Mexico: MEX (Mexico City), GDL (Guadalajara). Related IATA city code in this dataset: CUN. To turn a booked PNR that contains CUN into a customer itinerary, paste the cryptic text into the PNR parser.
