I guess what I was getting at was not a flight that's part of a late-late bank (like HP's flights through LAS), or B6's flight to OAK (although, I'll grant you that it is quite late), but as true a red-eye as possible -- one that would get you to the West Coast at a time when you'd normally start your day (or a perhaps a little earlier.)
Perhaps the Eastern flights were on such a schedule.
