— -- A system operated by the Federal Aviation Administration was back in service this afternoon after it experienced a problem earlier in the day that caused flight delays throughout the Northeast.
The FAA said it was "working with the airlines to return to normal operations, and expects to lift any remaining traffic management programs by 4 p.m. EDT."
"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 FAA added.
Earlier today, the FAA said it was "diagnosing an automation problem at an air traffic center in Leesburg, VA."
"Some flights into and out of the New York and Washington, DC metro area airports area may be delayed," the FAA warned.
Delays were reported at many Northeast airports, including Boston; Newark, New Jersey; John F. Kennedy, New York; Teterboro, New Jersey; Laguardia, New York; Philadelphia; Washington Dulles; Ronald Reagan Washington and Baltimore-Washington, according to the FAA website.
