Chetumal International Airport — Chetumal, Mexico

Capital of Quintana Roo state and hugging the border with Belize, Chetumal relies on the airport coded CTM to link its government offices and modest tourism sector with Mexico City and other domestic points. Unlike the Riviera Maya's crowded resort airports farther north, Chetumal's terminal stays comparatively quiet, serving travelers headed toward the multicolored Bacalar lagoon or Maya ruin sites such as Kohunlich and Dzibanche rather than beachfront crowds. Chetumal Bay borders the city just beyond the runway, and the historic role of the town as a smuggling and trading post lingers in its layered cultural identity.
