On February 19, 2023, a general strike announced by labor unions in Argentina has significantly impacted air travel, particularly affecting flights from Brazil. The strike is in response to proposed labor reforms by the Argentine government led by Javier Milei, drawing serious concerns from workers. As a result, flights from São Paulo's Guarulhos International Airport to Buenos Aires have been canceled, with Latam Airlines confirming the alteration of its operations due to the strike.

As highlighted by Latam Airlines, at least two flights originally scheduled for the morning of February 19 were unable to depart for Buenos Aires. The airline cited the strike implemented by the General Confederation of Labor (CGT) in Argentina, prompted by various unions joining forces against the government's labor policy changes. This cancellation has impacted many travelers and illustrates the cross-border repercussions of domestic labor disputes.

The strike showcases the tension between workers and the government over labor rights and economic policy in Argentina, which can resonate in neighboring countries like Brazil. The situation underlines the interconnectedness of regional economies and how labor movements in one country can disrupt services in another, particularly in the context of air travel, which is vital for business and tourism in South America.
