Bahías de Huatulco International Airport — Huatulco, Mexico

Serving the resort area along Oaxaca's Pacific coastline, Bahías de Huatulco International Airport, tagged with the code HUX, sits amid nine bays of clear water, sheltered beaches, and coral reef patches that draw snorkelers and divers. Developed deliberately as a planned tourism zone starting in the 1980s under Mexican government initiative, Huatulco grew with environmental protections built into its design, distinguishing it from the more built-up development seen in some other Mexican coastal resorts. The airport handles a combination of domestic flights from Mexico City and international charter and scheduled service from the United States and Canada, with traffic climbing noticeably during the winter high season. Surrounding national park land protects much of the coastline from further development, preserving the bays' relatively unspoiled character even as tourism grows.
