ATLANTA (AP) - Officials at Atlanta's airport say about two-dozen flights were canceled and others delayed because of a power outage.

Katena Carvajales, a spokeswoman for Hartsfield-Jackson Atlanta International Airport, says about 18 of the airport's 199 gates lost power for about seven hours Monday. Power was restored around noon. The cause of the outage wasn't immediately clear.

Delta Air Lines spokesman Anthony Black says the airline canceled about two dozen flights and was forced to delay some flights into Atlanta. He says some arrivals and departures had to be moved away from the gates that didn't have power.

Black says that Mondays are generally busy, and that this Monday is particularly busy because of the Thanksgiving holiday.
