Latin America’s aviation network continues to expand in 2025, with several airports emerging as critical hubs for both domestic and international travel.
Connectivity—how effectively an airport links passengers to multiple destinations—has become a key metric for assessing the strength of the continent’s air transport system.
From the bustling metropolises of Mexico and Brazil to the Caribbean gateways that tie the region together, these airports facilitate the flow of passengers, cargo, and commerce, shaping the economic and social landscape of South America.
Most Connected Airports in Latin America
Mexico has multiple airports that play key roles in regional connectivity. In 2025, Mexico City, Guadalajara, and Cancún are the most significant.
Mexico City International Airport (MEX) serves as the country’s primary international gateway. Aeromexico operates 57 percent of flights from MEX, providing an extensive network of domestic and international connections across the Americas and Europe.
The airport functions as both a destination and a transfer hub, enabling efficient connections for travelers heading to Central and South America.
Guadalajara International Airport (GDL) complements MEX by focusing on domestic connections and select international routes, particularly to the United States. Volaris operates 51 percent of flights at GDL, supporting business travel, regional tourism, and cargo movement.
Cancún International Airport (CUN) caters primarily to leisure travel. Vivaaerobus operates 16 percent of flights, but the airport maintains strong seasonal connectivity with North America and Europe.
CUN demonstrates how airports with a tourism focus contribute significantly to regional connectivity, even if airline dominance is lower than in larger hubs.
The Mexican airports illustrate the diversity of connectivity roles, balancing domestic demand, international linkages, and tourism-driven traffic.

Brazil and Immediate Neighbors: Continental Gateways
Brazil’s São Paulo–Guarulhos International Airport (GRU) is the busiest airport on the continent and a central hub for LATAM Airlines Group, which operates 53 percent of flights.
GRU links domestic destinations throughout Brazil with major international cities, supporting both business and leisure travel. Infrastructure developments and cargo operations enhance its significance as a continental gateway.
Peru’s Jorge Chávez International Airport (LIM) and Chile’s Comodoro Arturo Merino Benítez Airport (SCL) complement GRU’s connectivity. LATAM Airlines Group operates 61 percent of flights at each airport.
LIM serves as a gateway between the Pacific and Atlantic regions, while SCL connects Chile’s domestic cities and international destinations across the Americas.
Bogotá’s El Dorado International Airport (BOG) functions as a northern corridor hub. Avianca operates 53 percent of flights, linking Colombia efficiently to South America and North America.
Panama’s Tocumen International Airport (PTY) stands out with Copa Airlines controlling 90 percent of flights. PTY is widely regarded as the “Hub of the Americas,” connecting North and South America as well as the Caribbean with high efficiency.
These airports highlight the importance of major hubs in maintaining continental connectivity, balancing passenger flow, cargo operations, and regional integration.

Caribbean Gateways: Linking the Americas
Certain Caribbean airports play a critical role in connecting Latin America with the US and beyond. Luis Muñoz Marín International Airport (SJU) in Puerto Rico and Punta Cana International Airport (PUJ) in the Dominican Republic are prime examples.
JetBlue Airways operates 22 percent of flights at SJU, making the airport a key link between South America, the Caribbean, and the United States.
PUJ is more tourism-oriented, with JetBlue operating 12 percent of flights, yet it remains a critical hub for travelers moving across the Caribbean and the Americas.
These Caribbean airports demonstrate that connectivity is not solely about airline dominance or total flight numbers. Strategic location, seasonal travel patterns, and regional demand all contribute to their importance in the broader network.
