Santa Rosa - Artillery Colonel Victor Larrea International Airport — Santa Rosa, Ecuador

ETR represents Santa Rosa International Airport in El Oro Province, Ecuador, near the city of Santa Rosa and not far from the larger city of Machala. Despite its international designation, the airport primarily handles domestic traffic connecting this banana-export region of southern coastal Ecuador with Quito and Guayaquil. The surrounding area is one of Ecuador's key agricultural zones, particularly for banana production, and air links help move business travelers and goods-related personnel efficiently through a region where road travel to the capital can be lengthy. ETR's runway and terminal are modest in scale, consistent with its role serving a mid-sized provincial economy rather than a major metropolitan center.
