It is quite rare. LAX sits right next to the Pacific and the prevailing winds are mostly from west to east. When the Santa Ana's blow from the east to west, it is not uncommon to see the pattern switch. Also, when it rains (I spoke to a Polar Air pilot about this) and visibility is low, they tend to use the reverse pattern ILS. If you ever land at LAX prior to 6am, you will also land from west to east in most cases due to the noise abatement.
Iv'e also seen them maintain the normal pattern while other city's experience Santa Ana winds. Santa Ana's don't seem to effect LAX as much. It generally seem more common during the winter as a low pressure system effects SoCal.
"Some pilots avoid storm cells and some play connect the dots!"
Mixed flow occurs only late night (after midnight/1am) as a noise abatement practice. In general the longer runway Southside of the airport is used for takeoff, while Northside if for landings with aircraft maintaining visual separation from each other. However with low traffic volume I've seen landings and takeoff's occur on opposite ends same runway also.
Only other time this operation takes place is during times like 4th of July or New Years, with ATC not wanting aircraft to be hit with gunfire, so its keeps all ops over water as a safety measure.
If winds, or low ceilings preclude mixed flow, then the traditional West or East flow is continued which allows for IFR ops.

In around fifteen roundtrips in/out of LAX, I've had it happen once. It was a flight DTW-LAX on a NW 752 and we landed from the west in the rain. I was surprised because I didn't feel any of the turns...

In years past when UAX did the ONT/LAX shuttle flights the first early morning departure from ONT always used the reverse pattern since arrival was before 6 am in EB120's pulling into the mid-field temporary terminal between DL and UA hangars. Of course, those days are long gone and now I have to take the LA freeway pattern commute from the Inland Empire which from my house is 75 miles taking anywhere from less than 90 minutes or up to 3.5 hours!

Yes, I believe that when my flight from OGG on a DL 764 landed at LAX, we used the southernmost runway, 7R. I'm not completely sure, but about 90%... Because I was sitting in the middle row of seats at the time. It was about 5.20 in the morning IIRC, so the night-time noise abatement was probably in effect. After we landed, the pilot took a wrong turn and we waited for almost 15' on the taxiway, making it hard to forget.

In 12 years in LA I've had 3 East departures and 6 over-water/East landings, only 1 of them during late evening/early morning mixed flow. Problem with East landings is that they have to stay at 10,000 until they hit the beach on the downwind leg and then start down.

Quoting netjetsintl (Reply 15): 14 years of flying, i've never landed Eastbound at LAX, not even as a passenger
The only one time I've landed east at LAX was on the early QF flight from SYD. I recall that after we landed, there was one more plane right after us that also landed east, but everything thereafter started going west.
