A Raleigh-Durham International Airport spokesman said at least 150 departures from RDU were affected by Saturday’s technical issues that snarled flight traffic along the East Coast.
The FAA announced late Saturday afternoon that the computer problem had been resolved and flights were returning to normal.
RDU airport spokesman Andrew Sawyer said a "ripple effect" could cause delays into Saturday night. Sawyer said stores and restaurants have been asked to stay open later to accommodate passengers.
Sawyer said that from around 11:30 a.m. until about 3 p.m., no flights were able to depart from the airport. Some arriving flights were able to land during that period.

The airport warned travelers to check with airlines for flight status.
The FAA says the problem at its flight control center in Leesburg, Virginia affected multiple airports. Other airports experiencing disruptions include the hub airports near Charlotte, Baltimore, Washington and New York, the AP reported.
The agency says it is working closely with airlines to return to normal operations.
"The FAA is continuing its root cause analysis to determine what caused the problem and is working closely with the airlines to minimize impacts to travelers," the agency said in an emailed statement to the AP.
Information posted on an FAA website indicated that part of the trouble was due a computer system known as ERAM that air traffic controllers used at 20 centers around the country that handle high-altitude air traffic, according to the AP. Installation of the system was completed earlier this year at the last of the centers, years behind schedule.
The FAA says it is directing high-altitude flights around the affected airspace. The problem is not believed to be caused by any accident or hacking.
