Southwest Airlines Cancelled 1,000 Sunday Flights Across the US, Cites Air Traffic Control and Weather As Issue

If you were attempting to get away this weekend on a Southwest flight, chances are you were grounded.

On Sunday Southwest Airlines canceled more than 1,000 flights over the weekend, blaming air traffic control issues and weather.

The airline canceled 29% of its schedule, as of 7 p.m. ET Sunday, according to flight tracker FlightAware. Southwest was the highest rate of the major U.S. airlines. Allegiant canceled 6% of its flights. American Airlines were forced to cancel 5% of its flights, and Spirit canceled only 4% on Sunday. On the previous day, Saturday, Southwest Airlines canceled more than 800 flights.

Southwest Airlines said they experienced weather issue in Florida airports at the start of the weekend, which ultimately compounded unexpected air traffic control issues in the region. Those issues caused delays and drove significant cancellations for the airlines starting Friday evening.

“We’ve continued diligent work throughout the weekend to reset our operation with a focus on getting aircraft and crews repositioned to take care of our customers,” said Southwest Airlines. “With fewer frequencies between cities in our current schedule, recovering during operational challenges is more difficult and prolonged.”
