Cozumel International Airport — Cozumel, Mexico

Ferries and cruise tenders aren't the only way to reach this Caribbean island; CZM handles steady scheduled and charter flights, heaviest in winter when North American travelers escape colder weather. Cozumel sits off the Yucatan Peninsula's eastern coast, separated from Playa del Carmen by a narrow channel, with surrounding waters forming part of the Mesoamerican Barrier Reef, the second-largest reef system on Earth. Diving and snorkeling sustain much of the island's economy, alongside cruise arrivals that can drop thousands of day-trippers ashore at once. CZM's single runway handles a mix of widebody charters, narrowbody flights from US gateways, and smaller aircraft linking to mainland Mexico. Quintana Roo authorities have steadily expanded terminal facilities to keep pace with rising visitor numbers each season.
