General José María Yáñez International Airport guide

General José María Yáñez International Airport (Aeropuerto Internacional General José María Yáñez, ICAO MMGM) serves the port city of Guaymas on the Gulf of California coast of Sonora. It opened in 1972 and is run by the Mexican Navy through Grupo Aeroportuario Marina, which took over from Aeropuertos y Servicios Auxiliares when the federal government assigned the airport to the Navy in 2024. The airport also hosts the Guaymas Naval Air Base of the Mexican Navy.

A single asphalt runway 2,350 metres long handles all traffic. Passenger numbers are small. The airport handled 7,846 passengers in 2025, against a peak of 49,655 in 2011, and recorded 2,913 aircraft movements in 2025. Scheduled service is limited to regional flights on Aéreo Servicio Guerrero, linking Guaymas with Guerrero Negro and Loreto in Baja California.

The terminal is a single-storey building with check-in counters, a departure lounge with two gates that open onto the apron, and a baggage claim area. It normally operates from about 07:00 to 19:00 and is closed overnight. Most visitors to Guaymas and the nearby resort of San Carlos arrive through Hermosillo International Airport instead, which has a wider choice of airlines.
