In a video Tuesday, Delta CEO Ed Bastian updated customers on the outage that led to disruptions in Delta's flight schedule, resulting in hundreds of canceled flights. He noted that the airline had canceled 800 flights Monday, triple the number of mainline Delta cancellations previously during the entire year. 

“This isn’t the quality of service, the reliability that you've come to expect from Delta Air Lines,"  Bastian said. "We’re very sorry, I’m personally very sorry.”

Bastian thanked customers for their patience and loyalty while acknowledging their frustration. "We’ll do everything we can to make sure this never happens again," he said.
