On October 19, a general strike organized by workers in Argentina, in response to labor reform proposals from President Javier Milei's government, resulted in flight cancellations affecting Brazil. The strike triggered the cancellation of at least two flights from major Brazilian airline Latam, which were supposed to depart from São Paulo's Guarulhos International Airport to Buenos Aires. Another major airline, Gol, also reported the need to cancel flights due to the strike.

At the Ministro Pistarini International Airport, commonly known as Ezeiza, the majority of the canceled flights were international, with disruptions impacting travelers from various countries. Some flights remained scheduled but were facing delays, further complicating the travel situation. LATAM issued a statement acknowledging the changes in their flight operations and recommended that passengers stay informed about possible schedule adjustments, as some flights might operate with modified times rather than outright cancellations.

The implications of this strike extend beyond just flight cancellations, reflecting deeper unrest and labor-related tensions in Argentina under the new administration. As workers mobilize against the proposed labor reforms that they believe may undermine their rights, the situation could escalate further, leading to more disruptions and broader impacts on both local and international travel dynamics between Argentina and its neighboring countries like Brazil.
