Colombia accelerates, Mexico stabilizes, and Puerto Rico softens — early 2026 data reveals shifting demand patterns within one of the region’s largest airport portfolios.
Diverging trajectories inside ASUR’s portfolio
January 2026 passenger data from Grupo Aeroportuario del Sureste (ASUR) offers more than a routine traffic update. Beneath the group’s headline 3.6% year-on-year increase — reaching 6.66 million passengers — lies a more telling story: aviation demand across Latin America and the Caribbean is no longer moving in unison.
Within a single airport portfolio spanning Mexico, Colombia and Puerto Rico, three distinct demand cycles are now visible. The contrast is sharp, and strategically significant.
Colombia emerges as the growth engine
Colombia delivered the standout performance of the month, with passenger traffic surging 15.0% year-on-year to 1.72 million passengers. The momentum is largely domestic-driven, with internal traffic climbing 18.3%, while international volumes rose 5.2%.
Medellín’s José María Córdova International Airport (MDE – Rionegro) remains the anchor of this expansion. Total traffic at the airport increased 16.3%, supported by a striking 21.4% surge in domestic demand. Secondary airports also posted double-digit growth: Montería (+18.1%), Carepa (+19.9%) and Quibdó (+14.7%).
The implication is clear: Colombia’s internal air mobility is strengthening, reinforcing Medellín’s role as a rising secondary hub within the Andean aviation system. Unlike leisure-driven spikes, domestic expansion typically reflects broader economic resilience and improved regional connectivity.
For ASUR, Colombia is no longer a peripheral asset. It is becoming the group’s principal growth vector.
Mexico: international resilience masks domestic softness
Mexico, which accounts for more than half of ASUR’s total passenger base, reported a modest 0.9% increase to 3.75 million passengers.
However, the underlying structure tells a more nuanced story. International traffic grew 2.5%, while domestic traffic declined 1.2%. This divergence suggests that Mexico’s early-2026 stability remains heavily supported by inbound tourism, particularly from the United States.
Cancún International Airport (CUN), the portfolio’s largest asset, recorded a slight 1.0% contraction overall. Given that Cancún represents over 70% of ASUR Mexican traffic, even marginal fluctuations carry systemic weight.
Meanwhile, several secondary airports demonstrated stronger momentum. Mérida expanded 12.9%, Veracruz 11.4%, and Villahermosa 6.8%, pointing to a gradual redistribution of traffic flows within the southeast region.
The broader question is whether Mexico’s domestic slowdown is cyclical or structural. If international tourism remains the primary growth driver, Mexico’s airport system may face increased sensitivity to external economic conditions in 2026.
Puerto Rico: a cautious start to the year
San Juan’s Luis Muñoz Marín International Airport (SJU) recorded a 2.1% year-on-year decline, with total passenger traffic reaching 1.19 million.
Domestic traffic fell 2.6%, while international volumes increased 1.8%. As in Mexico, international demand shows resilience. However, overall contraction suggests competitive pressures within the Caribbean aviation market.
San Juan operates in an increasingly dynamic environment, competing with rapidly expanding hubs such as Punta Cana and Panama City. A soft January does not define a yearly trajectory, but it does signal that the Caribbean competitive landscape remains fluid.
Fragmentation defines early 202
The most important takeaway from ASUR January traffic data is not the 3.6% group growth figure. It is the fragmentation beneath it.
- Colombia: strong domestic expansion and structural momentum
- Mexico: stable but tourism-dependent
- Puerto Rico: mild contraction amid regional competition
Within a single operator’s portfolio, aviation demand is moving at different speeds across markets. For investors, airport authorities and network planners, this divergence matters.
It suggests that 2026 will not be defined by a uniform regional recovery. Instead, competitiveness, economic resilience, and route strategy will increasingly determine performance outcomes.
For LATAM and Caribbean aviation, the skies may be growing busier — but not evenly so.
