The FAA stopped all departing flights from taking off from four SoCal airports this afternoon because of computer problems affecting air-traffic control.
LAX, John Wayne Airport in Santa Ana, Bob Hope Airport in Burbank and Ontario International Airport are the airports affected, according to KTLA.
LAX tweeted out at 2:13 p.m. that the FAA had issued a "ground stop." Although planes arriving at the airports are allowed to come in, departing flights are being held on the ground. It's not clear at this point when the ground control will be lifted.
They've advised passengers with scheduled flights to check with their airlines about expected delays.
The FAA has not commented on the situation yet.
UPDATE 4:00 p.m.: The ground control order has been lifted on all the SoCal airports and departing flights are now allowed to take off, reported NBC Los Angeles.
UPDATE 3:38 p.m.: The FAA has lifted the ground control order at Burbank and Ontario airports; the departing flights at those airports can now take off, according to City News Service. The FAA said in a statement at 3:30 p.m. that they were “gradually restoring the system," reported KTLA.
