Passenger Traffic Overview

Total passenger traffic increased by 11.3% in June compared to the same month in 2024. Domestic passenger traffic rose by 11.7% year over year (YoY), largely driven by Argentina, along with strong performances in Brazil and, to a lesser extent, Italy and Ecuador. Meanwhile, international traffic grew by 9.2%, with all operating countries contributing positively YoY—except Ecuador—and particularly strong results in Brazil, Argentina, and Italy. Notably, Argentina accounted for over 60% of the total traffic growth in June.

In Argentina, total passenger traffic increased by 14.2% YoY, driven by double-digit growth in both domestic and international segments. Domestic traffic continued its strong performance, rising by 13.4% YoY — marking four consecutive months of double-digit growth. JetSMART, which recently added another Airbus A320neo to its fleet — now totaling 16 aircraft — continued to gain market share, carrying 127% more passengers than in the same month last year. Aerolíneas Argentinas, which resumed its Córdoba–Posadas route, saw its market share decline by 5 percentage points; however, it transported 6% more passengers than in June 2024. Notably, domestic traffic was negatively affected by a one-day strike by Aerolíneas Argentinas workers. International passenger traffic also remained strong, increasing by a solid 14.7% YoY. Avianca began operating flights between Córdoba and Bogotá with three weekly frequencies, while Azul launched seasonal routes connecting Mendoza with Viracopos, as well as Bariloche with Viracopos, Porto Alegre, and Belo Horizonte. Also in June, LATAM resumed its São Paulo–Bariloche and Buenos Aires–Rio de Janeiro routes, while Air Europa increased its Córdoba–Madrid service from three to four weekly frequencies.

In Italy, passenger traffic grew by 7.2% 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 7.5% YoY, driven by a 12.9% increase at Florence Airport and a 3.9% increase at Pisa Airport. Domestic passenger traffic grew by 5.3% YoY, supported by a strong performance at Pisa Airport due to the increase in Ryanair’s flight frequencies, partially offset by a decline at Florence Airport.

In Brazil, total passenger traffic increased by 12.5% 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 10.8% YoY, while transit passengers increased by 13.9% YoY. Notably, although representing a small share of total traffic (5%), international traffic grew strongly by 22.9% YoY.

In Uruguay, total passenger traffic — predominantly international — remained largely flat, growing by 0.3% YoY. Azul Linhas Aéreas announced a new direct route between Montevideo and Campinas, with five weekly flights starting in July. This new connection will help strengthen ties between Uruguay and Brazil, facilitate passenger flows, and promote the development of new commercial and tourism opportunities.

In Ecuador, where security concerns persist, passenger traffic increased by 1.4% YoY. International traffic declined slightly by 0.3% YoY, mainly due to reduced operations to the U.S., while domestic traffic rose by 3.7% YoY, although high airfares continued to dampen travel demand.

In Armenia, passenger traffic increased by 9.3% 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.
