Southwest Airlines CEO Gary Kelly says things with the company are basically back to normal today. This comes after the Texas-based airline cancelled more than two-thousand flights from Saturday through yesterday, blaming it on weather in Florida and air traffic control issues. Speaking on CNBC, Kelly said claims of the issues being caused by an anti-vaccine protest by its employees are completely false. He added it takes several days to catch up when an airline gets behind with delays and cancellations. Kelly said the problems over the past few days were very unique and unusual, but wasn't "anything that Southwest caused."
