According to an FAA spokesperson, aircraft headed to LAX were held for a time at their respective departure airports "to space out flights."
The ground delay was initially expected to remain in effect until 1 p.m. but was canceled about 9:30 a.m. The move followed a complete ground stop that was lifted shortly after 8 a.m.
