What airport code is assigned to Tulum, Mexico?

The correct answer refers to the fact that Tulum, Mexico does not currently have an assigned airport code for an operational airport. While Tulum is a popular tourist destination, its main access points are through nearby airports, such as Cancún International Airport (CUN), which serves as the primary gateway for international travelers to Tulum. Therefore, no official airport code is designated specifically for Tulum itself, making "None" the right choice.

The other options represent airport codes that may exist for different locations or purposes but do not correspond to any active airport in Tulum, reinforcing that the absence of a specific code is indeed the accurate answer.
