Representatives from Southwest Airlines said the outage was also causing delays and cancellations at Richmond International Airport, Norfolk International Airport and Raleigh Durham International Airport. The airline said the large amount of delays could impact flights around the country as well.
As of 2 p.m. EST, Southwest said fewer than 200 of its flights were canceled due to the automation problem.
