Monthly Passenger Traffic Performance

(In million PAX)

Passenger Traffic Overview

Total passenger traffic decreased by 4.1% in June compared to the same month in 2025. Domestic traffic declined by 12.5% year over year, primarily due to lower traffic in Argentina. International traffic increased by 2.8%, with all operating countries posting year-over-year growth except Argentina. Overall traffic performance was supported by double-digit year-over-year growth in Armenia and continued growth in Italy, Brazil, and Uruguay, offset by declines in Argentina and Ecuador.

In Argentina, total passenger traffic declined by 13.0% year over year in June, reflecting lower domestic and international traffic volumes. Domestic traffic decreased by 18.0% year over year, primarily driven by reduced capacity at Flybondi, which operated only three aircraft during the month—representing approximately 30% of its originally scheduled fleet—as well as lower capacity at Aerolíneas Argentinas following fuel price increases. Meanwhile, JetSMART recorded year-over-year passenger growth despite scheduled maintenance affecting part of its fleet. The top three domestic destinations were Bariloche, Córdoba, and Mendoza, all with load factors exceeding 80%. International traffic declined by 4.3% year over year. While seat capacity remained broadly stable compared to June 2025, the load factor decreased by three percentage points. Regional capacity declined across most markets, mainly reflecting capacity adjustments by Aerolíneas Argentinas and GOL. June traffic was also affected by the FIFA World Cup, which had a temporary dampening effect on leisure and business travel as passengers postponed or adjusted their travel plans. The top three international destinations during the month were Santiago de Chile, São Paulo, and Madrid.

In Italy, passenger traffic increased by 4.0% year over year, reflecting growth across both the international and domestic segments. International traffic, which represented more than 80% of total passenger volumes, grew by 4.7%, supported by strong demand at both airports, led by Pisa International Airport. Domestic traffic also expanded, rising by 1.7%, with positive contributions from both Pisa and Florence airports.

In Brazil, total passenger traffic increased by 3.9% year over year. Domestic traffic, which accounted for almost 55% of total traffic, declined slightly by 0.8% year over year, while transit passengers increased by a strong 10.5% year over year. Brasília International Airport continues to benefit from its position as a key secondary hub within the domestic network.

In Uruguay, total passenger traffic, predominantly international, increased slightly by 0.3% year over year. Among other developments, Azul Linhas Aéreas Brasileiras recently launched a new Montevideo–Belo Horizonte route, operating two weekly frequencies.

In Ecuador, passenger traffic declined by 4.1% year over year, as ongoing security concerns continued to weigh on travel demand. International traffic increased by 3.4%, supported by strong demand on U.S. routes, the launch of new services by Avianca, JetBlue, and LATAM Airlines, and additional frequencies operated by American Airlines. Domestic traffic, however, declined by 10.8% year over year, as elevated airfares continued to constrain demand, compounded by reduced operations on the Guayaquil–Quito route.

In Armenia, passenger traffic increased by a robust 16.0% year over year despite disruptions related to the conflict in Iran, which resulted in flight cancellations and airspace restrictions across the region. However, the impact proved to be more limited than initially expected, as strong demand from Western and Eastern Europe, Asia, and Russia continued to support overall traffic growth. In addition, the new Wizz Air base at Zvartnots International Airport, launched in late 2025, together with several new airlines and destinations, continued to support the airport's strong performance.
