Yes, please update on how if at all you are being accommodated as your experience is not unique transiting through LAX at night at least from my travels.
Every single flight (on-time or slightly early) I've had into LAX in the later evening has been delayed on the ground because there either was no gates available or too much "traffic in the alley", so I understand your frustration.
In my case LAX is home, so it is only an inconvenience, but I do feel the pain of the people that always have to run off the plane to make connections, knowing that there is not much help if they don't make it. Unfortunately LAX is a very poorly run operation on pretty much every front from check-in to club to gate and has went from being ok before to significantly worse since the merger.
