Southwest Airlines canceled more than 1,000 flights, 27% of its schedule, on Sunday as disruptions that the airline blamed on air traffic control issues and bad weather affected the travel plans of thousands of customers.
“We experienced significant impact in the Florida airports [Friday] evening after an FAA-imposed air traffic management program was implemented due to weather and resulted in a large number of cancellations,” Alan Kasher, who oversees daily flight operations, told staff in a note on Saturday.
“No FAA air traffic staffing shortages have been reported since Friday,” the FAA said. “Some airlines continue to experience scheduling challenges due to aircraft and crews being out of place. Please contact the airlines for details about current flight schedules.”
