Operations at São Paulo International Airport, in Guarulhos, are back to normal this Saturday (14), according to GRU Airport, the concessionaire that manages the terminal. The situation occurs after a failure in United States air traffic control caused a stoppage of around four hours on Friday (13).
According to the concessionaire, ten flights were canceled due to incidents recorded in United States air traffic, with an impact on the operation in Guarulhos.
Early this Saturday morning, there were still reflections of the problem. Among the flights scheduled to arrive in Guarulhos by 7am, two were cancelled. Both would come from New York and were scheduled to land at 6:15 am and 7 am.
Other arrivals from the United States were delayed by three to four hours. Despite the changes recorded in the morning, movement was smooth at Guarulhos Airport.
In a note, GRU Airport advised that passengers should contact their airline directly to obtain updated information about their flights, possible changes and other guidance.

Despite the problems, there was no record of confusion among passengers at the airport this Saturday morning.

US resumed takeoffs after four hours of shutdown
The United States began resuming operations on Friday night. The United States Federal Aviation Administration (FAA) authorized the resumption at 8:15 pm East Coast time, 10:15 pm Brasília time.
The suspension of takeoffs lasted around four hours and was determined after air traffic control centers registered problems with radar and communication systems.
According to the American government, the equipment responsible for transmitting and organizing information between the centers was overloaded and began to present inconsistent data.
The government also reported that the immediate problem had been corrected and that operations could safely resume. Still, the expectation is that the effects of the strike will continue in the coming days.
US Transportation Secretary Sean Duffy warned that airlines will need time to reorganize operations.
"It's going to be slow," Duffy told reporters at the White House.

Experts in the airline industry estimate that the effects of the stoppage could last for several days, even after operations resume.
Ten flights from Guarulhos to the USA were canceled on Friday (13)
On Friday (13), the concessionaire GRU Airport informed TV Globo and g1 that it had received a safety alert so that air traffic originating or ending in the United States would remain on the ground until further notice.
Of the 15 flights to the United States scheduled to leave Guarulhos, ten were canceled and two were delayed.
The canceled flights were operated by American Airlines and Latam and included destinations such as Miami, New York, Dallas, Los Angeles and Boston. Another seven flights operated by United Airlines and Delta were confirmed at the time of the investigation, with destinations such as Chicago, Houston, Washington, Atlanta and New York.
Airlines said Friday they were monitoring the impacts of the shutdown and working to assist affected passengers. Latam, for example, reported that it sought to offer "possible alternatives to passengers who may be affected, including flexibility options to facilitate the rescheduling of their trips."
