Passenger
Traffic Overview
Total
passenger traffic increased by 5.5% in March compared to the same month in 2025. Domestic traffic decreased by 2.4% YoY, mainly driven
by a decline in Argentina, partially offset by YoY improvements in Brazil and Ecuador. International traffic, meanwhile, grew by 12.2%,
with all operating countries contributing positively on a YoY basis except Brazil, including double-digit growth in Argentina, Italy,
and Ecuador. March performance in Armenia was partially impacted by disruptions related to the conflict in Iran, which led to flight
cancellations and airspace restrictions across the region.
In
Argentina, total passenger traffic increased by 2.7% year-over-year in March, driven by strong international demand, which more
than offset a decline in domestic traffic amid a tough comparison base following a strong 2025. Domestic traffic declined by 4.3% year-over-year,
reflecting reduced capacity from Aerolíneas Argentinas and Flybondi, partially offset by increased activity from JetSMART. The
top three domestic destinations were Bariloche, Iguazú, and Córdoba. International traffic remained robust, rising by 15.6%
year-over-year, supported by low-cost carriers such as JetSMART, Flybondi, Copa, Arajet, and LEVEL. The top three international destinations
in March were Rio de Janeiro, Santiago, and São Paulo.
In
Italy, passenger traffic increased by 9.3% YoY, driven by double-digit growth in the international segment, partially offset by
a decline in domestic traffic. International passenger traffic, which accounted for nearly 80% of total traffic, rose by 12.4% YoY, reflecting
solid performance at both Florence and Pisa airports. Domestic passenger traffic declined slightly by 0.3% YoY, primarily due to lower
volumes at Florence airport, partially offset by increases at Pisa airport.
In
Brazil, total passenger traffic increased by 12.2% year-over-year, reflecting improved traffic trends following a sustained period
of challenges in the aviation environment. Domestic traffic, which accounted for nearly 60% of total traffic, rose by 2.5% year-over-year,
while transit passengers increased by a strong 29.9% year-over-year. Growth was also supported by a post-Carnival rebound in corporate
demand, with Brasília benefiting from its position as a key secondary hub within the domestic network.
In
Uruguay, total passenger traffic, predominantly international, increased by 7.6% year-over-year, following a strong summer season,
including higher frequencies and the addition of temporary routes. Among other developments, Azul launched a new Montevideo–Belo
Horizonte route, operating two weekly frequencies.
In
Ecuador, where security concerns persist, passenger traffic performed well, increasing by 8.0% YoY. International traffic increased
by 13.7% YoY, supported by strong performance on routes to Europe. Domestic traffic rose by 3.3% YoY, although high airfares continued
to weigh on travel demand.
In
Armenia, passenger traffic increased by 4.4% year-over-year, driven by the addition of new airlines and routes, as well as increased
frequencies. Notably, in October 2025, Wizz Air established a new base at Yerevan’s Zvartnots Airport, deploying two aircraft and
launching ten new direct routes to Europe. March performance was partially impacted by disruptions related to the conflict in Iran, which
led to flight cancellations and airspace restrictions across the region.
Cargo
Volume and Aircraft Movements
Cargo
volume, excluding Argentina, increased by 3.5% year-over-year, driven by strong double-digit growth in Armenia and Brazil, which
was partially offset by declines in Italy, Uruguay, and Ecuador. By country, performance was as follows: Armenia (+24.5%), Brazil (+18.6%),
Uruguay (-16.8%), Ecuador (-14.6%), and Italy (-20.0%). In Argentina, cargo volume data remains under review to ensure consistency and
accuracy.
Aircraft
movements increased by 3.3% YoY, with positive contributions from all countries of operation except Ecuador, which recorded a slight
decline. Performance by country was as follows: Italy (+11.8%), Brazil (+10.3%), Armenia (+1.3%), Argentina (+1.0%), Uruguay (+1.0%),
and Ecuador (-0.3%). Argentina, Brazil, and Italy accounted for more than 80% of total aircraft movements in March.
