Updated 7:37 a.m.: Flights resume
A nationwide ground stop on United Airlines flights has been lifted, according to the FAA.
All flights were grounded for a little more than an hour Wednesday morning due to a computer glitch.
"The airline corrected the problem and planes are moving again," Lynn Lunsford, spokesperson for the Federal Aviation Administration, told KPCC in an email.
A statement on United's website noted that a waiver will be available for customers who are able to change their flight plans.
7:03 a.m.: United flights grounded nationwide; long waits at LAX
A computer glitch has forced United Airlines to ground all of its flights nationwide, causing a backup at Los Angeles International Airport.
United called to notify the airport early Wednesday, and though it did not use the term "grounded," the Federal Aviation Administration did, L.A. World Airports spokeswoman Nancy Castle told KPCC.
The problem is affecting the airline's ability to check people in, and "if you can't check in people, they can't really go anywhere," Castle said.
United sent the following notice via Twitter:
KNBC-TV reported that aerial video showed a line of people outside Terminal 7, home to United Airlines.
KPCC's Jon Cohn, managing producer for Crawford Family Forum programs and live events, was at the airport Wednesday. He said he was directed to wait at the end of the sidewalk at Terminal 7 and that everything was "moving very, very slowly, and then basically by the time that we got here, we were told that the FAA had grounded all United flights for the time being."
Cohn said they said they are starting to process people by hand and that it was "looking like it'll be a long day" for travelers.
