Southwest airlines cancels over 1,000 flights Sunday

Southwest said air traffic control issues and weather in Florida on Friday sparked delays and cancelations nationwide.

Southwest Airlines canceled more than 1,000 flights Sunday, blaming massive nationwide disruptions on weather and air traffic control issues in Florida two days prior.

The flight-tracking website shows that Southwest canceled 28% of its flights on Sunday while 600 more face delays. More than 800 Southwest flights were canceled Saturday and upwards of 1,100 flights were delayed, according to FlightAware.

For comparison, American Airlines has the second-most cancellations Sunday with 142, or 4%, as of 4:30 p.m. ET.

The colossal travel hiccup comes in the midst of a busy time for airlines — Monday is a federal holiday, meaning millions of American workers have a three-day weekend. More than 2.1 million people were screened at airport security checkpoints Friday, a volume that hasn’t been seen since early August, according to the Transportation Security Administration.
