What is the airport code for Cozumel, Mexico?

The airport code for Cozumel, Mexico, is indeed CZM. This code is derived from the IATA (International Air Transport Association) airport code system, which assigns unique three-letter codes to identify airports around the world.

In this case, CZM is specifically designated for Cozumel International Airport, reflecting its geographical location and ensuring that travelers, airlines, and booking systems can efficiently reference this airport. The use of the specific letters "CZM" helps distinguish it from other airports and their codes, creating a unique identity for Cozumel's airport in listings, reservations, and flight operations.

The other options represent different airports entirely: DAB is associated with Daytona Beach, Florida; DAY serves Dayton, Ohio; and CRW is the code for Yeager Airport in Charleston, West Virginia. Each of these codes relates to airports in the United States and is separate from Cozumel, further emphasizing why CZM is the correct choice for Cozumel, Mexico.
