Which city is represented by the city code CUN?

The city code CUN is the IATA (International Air Transport Association) code for Cancun, Mexico. Each airport around the world is assigned a unique three-letter code to simplify identification, particularly useful in international travel and ticketing processes. Cancun is a well-known tourist destination located on the Yucatan Peninsula, famous for its beaches, resorts, and vibrant nightlife, making its airport an important hub for travelers.

In contrast, the other cities listed have different airport codes: Denver International Airport is served by the code DEN; Dallas is primarily represented by DFW for Dallas/Fort Worth International Airport; and Detroit Metropolitan Airport uses the code DTW. Thus, recognizing that CUN specifically refers to Cancun provides clarity in the context of airline travel and city identification.
