Second Day Of Cancellations, Delays For Delta Airlines Following System Outage

ROMULUS (WWJ/AP) - A day after cancelling more than 1,000 flights due to a power outage, Delta Airlines is warning of more flight delays.

The airline says more than 100 flights will be cancelled and at least 200 will be delayed Tuesday morning. Executives say after the power failure in Atlanta, some critical systems and network equipment didn't switch over to a backup. Customers are encouraged to check their flight status before heading to the airport.

Delta canceled about 1,000 flights and had 2,900 others delayed, some for hours, after a power outage Monday at its Atlanta headquarters caused many computer systems to crash.

The airlines will be handing out refunds and travel vouchers as penance for the computer outage.

A spokesman for Georgia Power said that the company believes a failure of Delta equipment caused the airline's power outage. He said no other customers lost power. Delta declined to comment on the power company's report.

Flights that were already in the air when the outage occurred continued to their destinations, but flights on the ground remained there.

Delta ranks as the third-largest in the world by number of passengers carried, with 138.8 million travelers last year, according to industry group IATA. It was narrowly beaten only by American Airlines and Southwest Airlines, with all of them flying mostly within the United States.

Airlines depend on huge, overlapping and complicated systems to operate flights, schedule crews and run ticketing, boarding, airport kiosks, websites and mobile phone apps. Even brief outages can snarl traffic and cause long delays.

Delta said customers whose flights were canceled or delayed more than three hours could get a refund and $200 in travel vouchers. Travelers on some routes can also make a one-time change to the ticket without paying Delta's usual change fee of $200 for domestic flights and up to $500 for international flights.
