(CNN) -- A computer problem at a Virginia air traffic control center led to significant flight delays Saturday at airports in the Washington and New York City areas, the Federal Aviation Administration said.

The FAA \"is diagnosing an automation problem at an air traffic control center in Leesburg, Virginia,\" FAA spokeswoman Kathleen Bergen told CNN shortly before 1 p.m. ET.

\"We are directing high-altitude traffic around the affected airspace,\" Bergen said.

Airports with delays included Baltimore-Washington International Airport, where departures were stalled up to two hours as of 1:15 p.m. ET, the FAA said.

\"We are working on rerouting aircrafts that were planned,\" Delta Air Lines spokesman Morgan Durrant said. \"We have to make last-minute adjustments to flight plans. Flights in and out of the three major D.C.-area airports may be delayed.\"

The FAA's Air Traffic Control System Command Center's website indicated that a power failure at the Virginia air traffic control center triggered the problem
