Monthly Passenger Traffic Performance

(In million PAX)

Passenger Traffic Overview

Total passenger traffic declined by 3.8% in August compared to the same month in 2023, or 1.5% when adjusting for the discontinuation of Natal airport. This represents a sequential improvement compared to the YoY decline of 4.2%, or 1.8% excluding Natal, reported in July. Domestic passenger traffic decreased by 12.6% YoY, or 8.9% when excluding Natal, primarily due to weaker YoY performance in Argentina. International traffic increased by 5.8%, mainly driven by growth in Argentina and positive YoY contributions from all countries except Armenia.

In Argentina, total passenger traffic declined 6.0% YoY, driven by weaker performance in domestic traffic, which was down by 10.4% YoY, improving from the 11.5% decline posted in July. Domestic traffic, which last year benefited from incentives provided by a government program called 'Previaje' to boost domestic tourism, continued to be impacted by the prevailing recession in the country. However, certain tourist destinations, such as Bariloche, Iguazú, and Mendoza, continued to perform well. International passenger traffic increased by 8.3% YoY. Aerolíneas Argentinas suspended its EZE-JFK route, while Copa and Avianca increased the frequency of some of their routes. Passenger traffic in August was also affected by strikes organized by the aeronautical union.

In Italy, passenger traffic grew by 6.6% compared to the same month in 2023. International passenger traffic, which accounted for over 80% of the total traffic, increased by 7.1% YoY, with strong performances at both Pisa and Florence airports. Domestic passenger traffic increased by 4.0% YoY, driven by a 6.2% increase at Pisa airport which was partially offset by a decline of 1.2% at Florence airport.

In Brazil, total passenger traffic decreased by 8.1% YoY, or increased by 4.3% YoY when adjusting for the discontinuation of Natal Airport, up from the 3.3% YoY increase reported in July. These results reflect an improvement in traffic trends despite the still challenging aviation context and aircraft constraints in the country, along with the positive impact of the temporary closure of Porto Alegre airport. Domestic traffic, which accounted for almost 60% of the total traffic, was down 23.4% YoY, or 7.9% when excluding Natal, while transit passengers were up 22.0% YoY. As a reminder, following the friendly termination process concluded in February 2024, CAAP no longer operates Natal Airport, effective February 19, 2024. Therefore, statistics for Natal are available up to February 18, 2024.

In Uruguay, total passenger traffic, predominantly international, continued its recovery, increasing by a solid 13.4% YoY. In August, both SKY and LATAM Airlines announced they would resume their routes, Montevideo–Rio de Janeiro and Punta del Este–Santiago de Chile, respectively, for the summer season.

In Ecuador, passenger traffic decreased slightly by 0.8% YoY, showing a sequential improvement from the 5.1% decline recorded in July. International passenger traffic increased by 4.1% YoY, while domestic traffic decreased by 5.9% YoY, mainly due to the exit of the local airline Equair in October 2023 and high airfare prices.

In Armenia, passenger traffic decreased by 2.1% YoY, consistent with last month's performance and following a strong recovery in 2023, which benefited from the introduction of new airlines and routes, as well as an increase in flight frequencies. The introduction of new routes has continued into 2024.

Cargo Volume and Aircraft Movements

Cargo volume increased by 5.1% compared to the same month in 2023, with positive YoY contributions from Argentina (+3.8%), Uruguay (+8.4%), Armenia (+32.1%), Ecuador (+3.0%), and Italy (+8.4%), partially offset by a YoY decline in Brazil (-5.8%). Argentina, Brazil, and Armenia together accounted for 80% of the total volume in August.

Aircraft movements decreased by 5.4% YoY, with negative YoY contributions from Armenia (-10.1%), Brazil (-5.1%), Argentina (-7.4%) and Ecuador (-1.1%), which were partially offset by positive YoY variances in Uruguay (+1.5%) and Italy (+1.1%). Argentina, Brazil, and Italy accounted for more than 80% of total aircraft movements in August.
