LAX's troubles aren't over yet! Last night's delays at the airport are causing delays of an hour or more today as carriers struggle to service planes and position crews.
The trouble started yesterday at around 2 p.m., when customs computers containing information on passengers crashed.
Many people spent much of the night sitting on airport floors or waiting on LAX runways.
The machines were back on line by midnight, and customs officials say more than 20-thousand weary passengers were cleared by this morning.
However, departures are still being delayed so flight crews can get their mandatory sleep periods and aircraft can be cleaned.
Some flights to Europe and Asia have been reportedly been canceled.
Caroline O'Rourke, a visitor from Ireland who was caught up in the delays, called them "disgraceful."
