Delta Air Lines said it was cancelling nearly 250 flights on Tuesday as it looks to restore operations after a power outage hit its computer systems on Monday, causing the cancellation of about 1,000 flights.
"We were able to bring our systems back on line and resume flights within a few hours yesterday but we are still operating in recovery mode," Delta said in a statement on Tuesday.
An outage hit Delta's computer systems on Monday, grounding planes and stranding passengers of one of the world's largest carriers at airports around the globe.
Delta will be handing out refunds and travel vouchers as penance for the latest computer outage to knock a major airline off stride.
Delta canceled more than 700 flights and had 2,600 others delayed, some for hours, after a power outage Monday at its Atlanta headquarters caused many computer systems to crash.
The computer systems were working again a few hours later but Delta said it was still working to accommodate stranded passengers.
Its challenge Tuesday will be to find enough seats on planes during the busy summer vacation season to accommodate the tens of thousands of passengers whose flights were scrubbed. Last month, the average Delta flight was 87 percent full.
The airline posted a video apology by CEO Ed Bastian. And it offered refunds and $200 in travel vouchers to people whose flights were canceled or delayed at least three hours.
