I have been looking through this thread, great idea for one to keep track!

let me add my most recent flights this past weekend, and state that, aside from N/A flights on props and rjs, this weekend is the first in a long time that I can remember it Not being available, though I usually fly the same routes a lot.

9/4 UA 322 - SNA -> SFO (old livery A320)
9/6 UA 216 - SFO -> SNA ^ (new livery 735)
