Delta Airlines cancelled 530 flights Tuesday morning, according to a company statement released at 12:30 p.m. EST.
Operations resumed as systems were restored but by late afternoon Delta had canceled more than 650 flights.
Because of the ripple effect after the outage, numerous airline’s crews and airplanes were out of place.
In a video message posted to Twitter CEO Ed Bastian said: “I apologise for the challenges this has created for you with your travel experience at Delta”.
“Delta probably had some kind of catastrophic failure that took everything, even their backup systems offline, which left them dead”, Pearcy said.
Delta cancels almost 250 flights on Tuesday morning.
Making things worse for some passengers Tuesday morning, Delta’s flight-status updates weren’t working, as the Associated Press reports.
Airlines have been putting more people in each plane, so when a system of a major carrier crashes, as has happened with others before Delta, finding a new seat for those affected becomes more hard.
Delta also offered a travel waiver to its customers, which the company extended on Tuesday.
Osaka-bound flight 172, which was scheduled to depart from Guam on August 9 at 9 a.m. but was awaiting takeoff at 11:50 a.m., was expected to arrive in Osaka at 1:49 p.m.
The disruption was so severe on Monday that, at one point, Delta warned passengers that information provided by its employees, website and app may be out of date. He said the airline’s investigation into the cause of the outage was continuing but said there were no indications of hacking.
Dave Holtz, the airline’s senior vice-president of operations, said: “We are still operating in recovery mode”. Customers who gave their email addresses to Delta will receive the voucher in about a week, says the airline.
The outage raises questions over a recent wave of four U.S. airline mergers that resulted in four large carriers controlling 85% of domestic capacity, The Wall Street Journal reported.
