LOS ANGELES -- Police at Los Angeles International Airport said a large crowd in the sun waiting to get into Terminal 1 appeared to be merely the result of an unusual travel pattern, and not related to any unusual security event.

A reporter at the airport estimated at 10 a.m. Sunday that about 1,000 people were lined up outside Terminal 1, waiting to get through security.

The line, described by the reporter as "the longest I've ever seen at this terminal, and I fly here a lot," stretched west from the terminal doors past the adjacent Terminal 2 entrance.

People were shading themselves in the hot sun. The 10 a.m. LAX temperature was 86 degrees, and there was no breeze and a scorching sun.

Airport police told the LAX traffic radio station, AM 530, that officers were helping people in the line stay out of traffic on the busy upper deck.
