Story highlights The Federal Aviation Administration lifts its ground stop

Departure delays are reported in Los Angeles, Las Vegas and Salt Lake City

LAX is the sixth busiest airport in the world, third busiest in the United States

Computer issues prompted a temporary ground stop at Los Angeles International Airport (LAX) on Wednesday.

The computer failure occurred at the Federal Aviation Administration's Los Angeles Flight Center, which controls air traffic for the region.

All arriving flights that were inside the flight center's airspace at the time of the ground stop landed at the airport, according to LAX spokeswoman Nancy Suey Castles.

Approximately 10 inbound flights that were outside that airspace were diverted to other airports.

"Airlines at LAX are reporting an estimated 10 cancellations and 110 departure delays throughout tonight," the spokeswoman said.

Earlier, FAA spokeswoman Laura Brown stressed that radar was not down and that authorities hoped to resolve the computer glitch soon. The agency had warned of the potential for gridlock at some area airports, citing significant volume already en route.
