What is unreported is that LAX has to reverse takeoff pattern with planes taking off over the city because surface winds are from the east. Huge delays there, also.
This only happens maybe a day per year, some years never.
It happened to me once flying in there. I distinctly remember the pilot saying “We’re going to have a delay while they reverse the runways”, then he correcting himself, saying “Actually the runways are staying the way they are. It’s the traffic pattern that they’re reversing.”
