The protest of ANAC workers is scheduled for Thursday, September 3 and Friday, September 4. The assemblies and mobilizations will be concentrated from 9 a.m. to 12 p.m. and from 6 p.m. to 9 p.m.

What happens to flights on Thursday, September 3 and Friday, September 4

Passengers who have flights scheduled in Argentina on Thursday, September 3 and Friday, September 4 must consider possible alterations in their itineraries. The Association of State Workers (ATE) confirmed a 48-hour national measure that reaches workers of the National Civil Aviation Administration (ANAC) and that will be developed through strikes, assemblies and mobilizations in more than 27 airports.

The impact does not necessarily mean that all flights will be canceled. The critical point is in the time slots defined for the protest: from 9 a.m. to 12 p.m. and from 6 p.m. to 9 p.m. on both days. The impact on certain airport services can have knock-on effects on departures, arrivals, connections and rescheduling, even when a flight does not coincide exactly with the beginning of an assembly.

The information available at the close of this note does not allow us to affirm that there is a definitive list of canceled flights. The recommendation for travelers is to check the status of each operation directly with the airline and avoid going to the airport without previously confirming the situation.

📍 Where the measure will be felt

The protest has a federal scope and was announced in more than 27 airports. Among the most relevant terminals mentioned in the reports are Ezeiza and Aeroparque, as well as regional airports in different provinces.

🕘 Protest schedules

Outside these slots, the operation should continue, but the recovery of the system can take time and a one-off change can have an impact on subsequent flights.

💰 Why is the strike taking place?

According to the ATE statement, the conflict has as its axis the claim for wage and labor breaches that the union attributes to the national government. The union maintains that since January certain additional payments linked to parity agreements have not been paid and demands the reopening of sectoral negotiations.

·       Payment of salaries contemplating the agreed increases corresponding to extra-parity items.

·       Opening of the sectoral parity.

·       Financing for the operational tasks of the Rescue and Fire Fighting Service (SSEI) and for Inspection at airports.

ATE also maintains that working conditions have deteriorated and links the conflict to a loss of purchasing power that, according to its own estimate, exceeds 40% since the beginning of the current national administration. This figure is an assessment of the union and must be differentiated from an independent statistical measurement.

⚖️ A key point: ANAC is not the same as air traffic controllers

In the coverage of the conflict it is important to distinguish ANAC workers from air traffic controllers. ANAC is the civil aeronautical authority and has personnel dedicated, among other functions, to airport health, inspection and the Rescue and Fire Fighting Service. Air navigation services are managed by EANA, so a measure by ATE-ANAC should not be automatically presented as a strike of controllers.

ANAC itself had already clarified in a previous conflict that a ATE-ANAC measure did not necessarily imply an interruption of operational safety nor did it amount to a strike by controllers. For the September 2026 situation, the agency reported that the competent authorities are evaluating the scope and conditions of the measure.

📋 What the regulatory framework says about essential services

Argentine aeronautical regulations consider certain services related to air navigation essential and establish mechanisms to preserve minimum services during union measures. ANAC Resolution 173/2026 regulated the provision and modality of public and essential air navigation services during union actions and established operational continuity criteria.

Among other provisions, the regulation establishes that certain aircraft – such as public and health aircraft – should not be affected by the measure and contemplates rules for flights that are already in operation and for destinations with a single daily frequency. This constitutes a general regulatory framework and should not be confused with the specific union announcement of September 3 and 4.

🧳 What passengers should do

·       Check the status of the flight on the app, website or official channels of the airline before heading to the airport.

·       If the flight is confirmed, keep track because an operational modification may occur later.

·       Arrive with additional time if the company maintains the operation, especially in the strips near the beginning or end of the protest.

·       Do not assume that a cancelled flight is automatically rescheduled: check the airline's instructions.

·       If there is a connection, check each section of the itinerary separately.

·       Keep receipts of purchase, communications from the airline and extraordinary expenses in case of possible claims.

·       For health, humanitarian, organ and official flights, the situation has a differentiated treatment according to the ATE announcement.

🏙️ The impact on the country's connectivity

The relevance of the measure exceeds the passengers who take off during protest hours. Air transport works like a network: a delay at a headland can alter an aircraft's rotation, crew availability, passenger boarding on connections, and the scheduling of subsequent flights.

The risk is especially sensitive in the main connectivity nodes. Ezeiza concentrates a large part of international traffic and Aeroparque has a central role in domestic and regional connectivity. At airports in the interior, an interruption can have a proportionally greater effect when there are fewer daily frequencies and fewer immediate land alternatives.

🗣️ Two positions in the face of the conflict

ATE maintains that the protest is a consequence of the lack of responses to its demands for wages and operational financing. The union's general secretary, Rodolfo Aguiar, said that the organization communicated the measure in advance to open a negotiation instance.

From the official side, ANAC indicated that it is evaluating the scope and conditions of the measure and recalled that aeronautical activity involves essential services subject to minimum benefits. The difference between the two positions will be decisive in knowing the final operational impact.

🔎 Can there be an extension of the conflict?

ATE warned that, if a dialogue is not opened, the conflict could deepen. For now, the announced measure covers Thursday, September 3 and Friday, September 4, 2026. Any extension, modification of schedules or new call must be considered a novelty and should not be anticipated as a confirmed fact.
