OK, a way out flight, but HKG-SFO with R=0 since purchase a couple or three months ago.
Well, paranoid me check at least once a day, and all of sudden I see R=8
So I call, agent thinks a bit, then goes ahead and does u/g ^
An hour or two later, it's R=0 again, and on seatmap I see EXACTLY one less Biz seat taken

Hard to belive I was the only one on u/g list
Now for MY QUESTION:
Withdrew my RPU for DFW-OGG, but now that my DFW-LAX cleared via CPU, am I safe in applying RPU and having it redeposited when it does not clear, since it's F=1 three days out.
