Delta chief accepts responsibility for outage

Delta Air Lines chief executive Ed Bastian took responsiblity for a computer glitch that grounded its fleet this week, according to an interview published Thursday.

"This is our responsibility," Bastian told the Wall Street Journal. "The buck stops here."

Bastian said there was "nothing endemic" in terms of problems afflicting Delta's computer systems and that he was confident the carrier would be able to resume at normal levels on Thursday after canceling hundreds of flights on each of the past three days.

On Monday, Delta grounded its global fleet for six hours due to a computer snafu it said was caused by a power outage in Atlanta, where the airline is based.

The glitch delayed thousands of flights and caused about 2,000 others to be canceled altogether.

The episode raised questions about the state of Delta's information technology systems.

"It's not clear the priorities in our investment have been in the right place," Bastian told the Journal. "It has caused us to ask a lot of questions which, candidly, we don't have a lot of answers for."
