Delta has begun clearing its backlog following the airline’s global grounding after its computer systems went down yesterday.
The airline said several applications were affected, including its website, leading to the cancellation of over 700 flights yesterday.
Delta has apologised and has offered refunds and travel vouchers to passengers whose flights were cancelled or who were delayed for over three hours.
Delta said its ‘ground stop has been lifted and limited departures are resuming’, but it warned of delays and cancellations and advised customers to check the status of their flights.
Delta’s codeshare partner Virgin Atlantic said its aircraft were operating normally, but told passengers to check their tickets in case their particular flight was operated by Delta as part of the code share.
A statement on Delta’s website said: "A power outage in Atlanta, which began at approximately 2:30 a.m. ET on Monday has impacted Delta computer systems and operations worldwide, resulting in flight delays.
"Large-scale cancellations are expected today. All flights enroute are operating normally. "We are aware that flight status systems, including airport screens, are incorrectly showing flights on time.
"We apologise to customers who are affected by this issue, and our teams are working to resolve the problem as quickly as possible."
