Delta Air Lines lifts ground stop on flights after worldwide outage

HOUSTON (KTRK) -- Delta Air Lines says a ground stop on flights has been lifted, and limited departures will resume after a unspecified systems issue delayed travelers internationally.

Earlier this morning, Delta grounded flights scheduled to leave today.

Confirmation of Monday's troubles came in an official account that responds to customers via Twitter. The airline declined to immediately comment by phone and it was unclear whether all its flights were affected.

"A power outage in Atlanta, which began at approximately 2:30 a.m. ET, 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 apologize to customers who are affected by this issue, and our teams are working to resolve the problem as quickly as possible. Updates will be available on news.delta.com."

The company said its IT systems were down everywhere and "hopefully it won't be much longer."

Several applications were affected, including the company's website.
