The impact of Delta's Monday morning power outage has extended into a second day, with the airline on Tuesday cancelling about 300 flights as it scrambles to bring its systems back online.
In a Tuesday morning update, Delta said it is still working to "reset" operations and "get crews, aircraft, and other operational elements in place to take care of customers."
An electrical problem at its Atlanta headquarters early Monday morning, forcing the airline to cancel around 1,000 flights yesterday.
"We were able to bring our systems back on line and resume flights within a few hours [Monday] but we are still operating in recovery mode," Dave Holtz, senior vice president of Delta's operations and customer center, said in a statement.
"We are sorry for what many of our customers have experienced over the past 24 hours, including those who remain at airports and continue waiting for their flights," Holtz said. "We are doing everything we can to return our operation to normal reliability, but we do expect additional delays and cancellations."
Customers scheduled to travel this week should check the status of their flight on Delta's website or via the Fly Delta App.
The company is offering compensation to customers "significantly affected" by delays or cancellations——which will likely add up to millions of dollars in lost revenue, The Wall Street Journal estimated.
As the Journal pointed out, the fiasco highlights the vulnerability of Delta's computer systems, which run "everything from flight dispatching to crew scheduling, passenger check-in, airport-departure information displays, ticket sales and frequent-flier programs."
