Delta Air Lines resumed US domestic flights after a computer glitch grounded about 150 flights and left passengers stranded across the country.
The two and a half hour systems outage occurred last night prompting cancellations and delays, particularly at Delta’s hub airports.
The Atlanta-based airline’s chief executive Ed Bastian said: “I want to apologise to all of our customers who have been impacted by this frustrating situation.
“This type of disruption is not acceptable to the Delta family who prides itself on reliability and customer service. I also want to thank our employees who are working tirelessly to accommodate our customers.”
It was the second disruption among major US airlines in a week, after United Airlines grounded domestic flights following a computer failure.
The United outage also lasted about two and a half hours but resulted in relatively few cancellations.
