Passenger Traffic Overview

Total passenger traffic increased by 10.2% in August compared to the same month in 2024. Domestic passenger traffic rose by 10.4% year over year (YoY), largely driven by Argentina, along with strong performances in Brazil and, to a lesser extent, Italy. Meanwhile, international traffic grew by 9.6%, with all operating countries contributing positively YoY—except Uruguay—and particularly strong results in Argentina, Italy and Armenia. Notably, Argentina accounted for two thirds of the total traffic growth in August.

In Argentina, total passenger traffic increased by 13.5% YoY, driven by double-digit growth in both international and domestic segments. Domestic traffic maintained its strong performance, rising by 10.4% YoY despite the strike organized by the ATEPSA union on August 22, 24, and 26. International traffic also remained solid, increasing by 18.9% YoY, with particularly strong results on the Buenos Aires–Madrid route, which operated six daily flights with load factors of 94%. The winter season reached record highs in Bariloche and Mendoza, which were the destinations with the highest YoY growth among international travelers. Similar to domestic traffic, international operations were also affected by the ATEPSA union strike on August 22, 24, and 26.

In Italy, passenger traffic grew by 6.8% 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 6.7% YoY, driven by a 10.5% increase at Florence Airport and a 4.4% increase at Pisa Airport. Domestic passenger traffic grew by 6.9% YoY, supported by a strong performance at Pisa Airport (+10.9%) due to the increase in Ryanair’s flight frequencies, partially offset by a 3.5% decline at Florence Airport.

In Brazil, total passenger traffic increased by 10.2% YoY, reflecting an improvement in traffic trends despite ongoing challenges in the aviation environment. Domestic traffic, which accounted for almost 60% of total traffic, rose by a strong 13.7% YoY, while transit passengers increased by 4.9% YoY. Notably, although representing a small share of total traffic (5%), international traffic grew by 13.5% YoY.

In Uruguay, total passenger traffic, predominantly international, declined by 6.3% YoY. The year-over-year comparison was affected by JetSMART’s removal of the Montevideo–Buenos Aires route in the second half of 2024. In addition, traffic in August was impacted by a four-day scheduled closure of operations due to the installation of the new Category IIIb Precision Instrument Landing System (ILS CAT IIIb) on the main runway.

In Ecuador, where security concerns persist, passenger traffic increased by 2.0% YoY. International traffic grew by 3.6% YoY, mainly driven by JetBlue’s increased operations to New York and Avianca’s additional frequencies on its routes to New York, Bogotá, Medellín, and Buenos Aires. Domestic traffic rose by 2.3% YoY, although high airfares continued to weigh on travel demand.

In Armenia, passenger traffic increased by 7.2% 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.
