The data is on the website flightaware.com and is being quoted by the AFP agency.
The situation was even worse the day before, according to the same specialized website, which on Friday recorded around 3,060 canceled flights and almost 8,000 delays.
This situation is associated with a staff reduction of about 15% in US airlines compared to the period before the covid-19 pandemic.
Companies in the sector say they are working to solve the problem, intensifying campaigns to recruit pilots and other categories of personnel and reducing the number of seats available for passengers.
Airline employees mention other aggravating external factors, in particular weather or due to covid-19.
In a publication on the social network Twitter, the Secretary of Transport of the United States, Pete Buttigieg, today reminded passengers that they are entitled to a refund in case of flight cancellation.
