Fly through LAX and I think that you will find your success rate goes WAY up.
TiteG4 - I think that MillionMiler's reasoning is correct, although in application it seems spotty.
I have only AA status, so I guess I am getting lucky.
YVR-HKG seems to happen because they filled the J seats in New York, and so they bump me up to first.
ICN-TPE just because they like my face - the airplane wasn't full.
LAX-HKG appears to be because J is full.
