United flights are getting back on track at LAX after the airline grounded its entire fleet of 757s on Tuesday.

United pulled the planes because some follow-up inspections of on-board computers had been done incorrectly.

The airline has inspected most of the 96 planes it grounded. The process took about an hour for each plane, which led to dozens of delays and cancellations.
