Robert Mann, an aviation consultant and former American Airlines executive, said it likely will be Tuesday before Delta's operations in Atlanta return to normal, and for passengers "it could be most of the week" because there aren't many open seats on other flights in the last week before Christmas.
- Operations are slowly returning to normal at Atlanta's Hartsfield-Jackson International Airport Monday morning after a power outage that lasted almost 11 hours Sunday and crippled air travel at the nation's busiest airport.
Officials are investigating the cause of the fire and declined to rule out terrorism as of late Sunday, NBC News reported. His Delta flight home to Atlanta for the holidays was stuck on the airport's tarmac at 2:00 p.m. Sunday.
But what caused the power outage at the Atlanta airport? The blackout forced airlines to either cancel flights altogether or divert them.
The mayor called about 10 p.m. and asked for assistance.
According to RDU's website, at least two different departing flights are cancelled for this morning. "We certainly understand that the outage has caused frustration and anger, and we're doing everything that we can to get folks back home right away".
The lights flickered on shortly before midnight, after an exhausting day for travelers, that had left thousands stranded in dark terminals and on planes sitting on the tarmac.

Some passengers told CNN that airport and airline staff offered no updates as hours passed, leaving people scanning their phones and tablets for information.
CNN Producer Betsy Klein was stuck on a plane that had just landed in Atlanta after the outage. Delta announced Sunday night that another 300 flights were canceled Monday, as well.
The blackout led the Federal Aviation Administration to declare a ground stop at the airport, preventing Atlanta-bound flights in other airports from taking off and causing inbound flights to be diverted. The utility said that there are "many redundant systems in place" to ensure the power supply to the airport and that such outages at the airport "are very rare".
Delta, with its biggest hub operation in Atlanta, will be hardest hit.
No areas outside of the airport were affected by the power loss. "However, departures are delayed because airport equipment in the terminals is not working".
It is not known how many flights may be affected.
Thousands of people are stranded Monday morning at Hartsfield-Jackson Atlanta International Airport, where more than 1,000 flights were grounded just days before the start of the Christmas travel rush.
The airport handles some 275,000 passengers a day.
