Sierra Maestra International Airport — Manzanillo, Cuba

Sierra Maestra International Airport (MZO) serves Manzanillo, a port city on Cuba's southern coast in Granma province, named for the nearby Sierra Maestra mountain range historically associated with the Cuban Revolution. MZO primarily handles domestic flights within Cuba and limited charter service, supporting the region's agricultural and fishing economy as well as visitors interested in revolutionary history sites and the mountainous interior. Compared to Cuba's major tourist airports like Havana or Varadero, MZO sees modest passenger volumes and infrastructure, reflecting Manzanillo's role as a regional rather than international tourism center, despite its official 'International' designation.
