This summer travel season has been plagued with flight cancellations and delays as airlines struggle with staffing shortages, severe weather and delays in air traffic control.
As of Saturday evening, at least 636 flights to, within or out of the United States were canceled and another 5,921[ads1] domestic flights were delayed, according to FlightAware.
Newark Liberty International and Chicago Midway International Airport topped the list of US airports with the highest number of canceled flights, the flight tracking website reported.
American Airlines canceled 4% and delayed 24% of its Saturday flights, according to its website.

“We continue to work through a number of weather-related challenges across the country this weekend,” Southwest Airlines told CNN in a statement Saturday. “Our teams are working to get our customers to their destinations safely and as quickly as possible.”
CNN has reached out to the other domestic carriers for comment on Saturday’s delays and cancellations.
The department said it had been inundated with complaints from airline passengers seeking refunds since the start of the Covid-19 pandemic.
