Some flights are resuming at Baltimore-Washington International Thurgood Marshall Airport after a computer problem at a federal air traffic center grounded flights throughout the region, airport officials say.
Customers should check with their airlines for updated flight status information, they said. Delays could continue into the evening as airlines restart operations following the technical glitch.
Flights to and from the New York and Washington metro areas were also affected by the "automation problem" at an air traffic center in Leesburg, Va., the Federal Aviation Administration said in a statement.
BWI spokesman Jonathan Dean said the problem began around late morning.
By late afternoon, the automation service was back in service, according to the FAA.
"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 a statement.
Flights at BWI, Reagan National Airport and Dulles International Airport were limited during the outage, according to BWI officials.
