Fog Causes 142 Flight Cancellations or Delays at Carrasco Airport in 2026, Affecting Over 20,600 Passengers

Carrasco Airport has experienced significant disruptions in 2026, with 142 flights canceled or delayed and over 20,600 passengers impacted by dense fog. These issues stem from the limited visibility that hampers aircraft landing operations. The situation has drawn criticism from the opposition, particularly concerning the delayed activation of the airport's new ILS CAT IIIB landing system, which is intended to improve conditions during heavy fog.

These figures include passengers departing from the airport; we have not accounted for those who miss connections.

Diego Arrosa, CEO of Aeropuertos del Uruguay, provided the figures during a session that proceeded without Minister Sandra Lazo, who faced criticism for not attending a National Defense Commission meeting. Arrosa explained that the new landing system, which commenced construction in 2025 and was completed in January, has been delivered to the Directorate of Civil Aviation and Aeronautical Infrastructure (Dinacia). Test flights have confirmed the system's readiness.

“

the operation is the responsibility of 'air traffic controllers' and that according to what has been indicated, it remains for 'some officials to take the corresponding training courses for it to be 100% covered'

However, the full operationalization of the ILS CAT IIIB system is pending the completion of training for air traffic controllers. Arrosa stated that while the system and infrastructure are ready, "some officials need to take the corresponding training courses" to ensure 100% coverage. The original deadline for this training was June 15. Arrosa clarified that the responsibility for this training and the transition to the new system lies with Dinacia, and he is uncertain about the exact stage of completion.

“

That is a Dinacia issue and how the transition from one system to another is managed. I don't know what stage it is in, whether that training is finished or about to be finished, but the system, the technology and the work is finished and delivered.

Jorge Navarro, corporate manager at Aeropuertos del Uruguay, added that the national aeronautical authority has not yet officially authorized the system's use, despite its technical readiness. Christian Rodríguez, president of the Chamber of Aeronautical Commerce of Uruguay, highlighted the financial implications for airlines. These include costs associated with passenger delays, missed connections, operational stress, and expenses for amenities, accommodation, and meals when flights are significantly rerouted or grounded.

The customers can be affected by the delay itself or because they have missed their connection with other flights. It can be for ten minutes or for a whole day. Furthermore, it causes stress in the operation of any airline and generates additional costs.
