PassengerTraffic Overview

Total passengertraffic increased by 8.2% in July compared to the same month in 2024. Domestic passenger traffic rose by 9.0% year over year (YoY), largely driven by Argentina, along with strong performances in Brazil, Italy and, to a lesser extent, Ecuador. Meanwhile, international traffic grew by 7.2%, with all operating countries contributing positively YoY—except Uruguay—and particularly strong results in Argentina, Brazil, Italy and Armenia. Notably, Argentina accounted for over 70% of the total traffic growth in July.

In Argentina, total passenger traffic increased by 11.4% YoY, driven by double-digit growth in international traffic and high single-digit growth in domestic traffic. Domestic traffic continued its strong performance, rising by 9.9% YoY. JetSMART continued to gain market share, adding another Airbus A321neo to its fleet—now totaling 17 aircraft—with capacity for 230 passengers. Aerolíneas Argentinas began operating the Córdoba–Esquel route and incorporated a new Boeing 737 MAX 8 into its MAX family, as part of its narrow-body fleet modernization plan. International traffic also remained strong, increasing by 13.2% YoY. LATAM increased frequencies between Córdoba and Lima, offering for the first time ten weekly flights, initially on a seasonal basis. JetSMART inaugurated its Buenos Aires–Recife route with four weekly flights, while GOL resumed seasonal service from São Paulo to Bariloche with three weekly flights. Notably, operations at Aeroparque and Ezeiza airports were temporarily affected by adverse weather conditions on July 8.

In Italy, passenger traffic grew by 6.5% compared to the same month in 2024, mainly supported by an increase in flight frequencies by Ryanair. International passenger traffic — which accounted for over 80% of total traffic — rose by 5.9% YoY, driven by a 12.4% increase at Florence Airport and a 2.1% increase at Pisa Airport. Domestic passenger traffic grew by 8.2% YoY, supported by a strong performance at Pisa Airport due to the increase in Ryanair’s flight frequencies, partially offset by a 3.3% decline at Florence Airport.

In Brazil, total passenger traffic increased by 6.0% YoY, reflecting an improvement in traffic trends despite ongoing challenges in the aviation environment and aircraft constraints in the country. Domestic traffic, which accounted for nearly 60% of total traffic, rose by 7.8% YoY, while transit passengers increased by 2.7% YoY. Notably, although representing a small share of total traffic (6%), international traffic grew by 10.0% YoY.

In Uruguay, total passenger traffic — predominantly international — declined by 5.5% YoY. Azul Linhas Aéreas inaugurated a new direct route between Montevideo and Campinas, with five weekly flights. Traffic in July was impacted by the removal of the Montevideo–Buenos Aires route by JetSMART, as well as several days of adverse weather conditions that led to flight cancellations.

In Ecuador, where security concerns persist, passenger traffic remained largely flat YoY. International traffic declined slightly by 0.7% YoY, mainly due to reduced operations to the U.S., while domestic traffic rose by 2.1% YoY, although high airfares continued to dampen travel demand.

In Armenia, passenger traffic increased by 6.8% YoY. Travel demand has benefited from the introduction of new airlines and routes, as well as increased flight frequencies. Wizz Air recently announced the opening of a new base at Yerevan’s Zvartnots Airport, with two aircraft and eight new direct routes to Europe.

Cargo Volumeand Aircraft Movements


Cargo volumeincreased by 2.1% compared to the same month in 2024, with positive YoY contributions from all countries of operations except for Ecuador and Brazil.

Argentina, Brazil, and Armenia accounted for almost 80% of the total cargo volume in July.

Argentina, Brazil, and Italy accounted for more than 80% of total aircraft movements in July.
