1. What is the best chance for R space? Does it show up at certain times before a flight? I've been looking at trying to book some TATL/TPAC flights for next year and I'm just not seeing any R, anytime near when I want to fly.

2. I'm doing BOM-EWR this weekend and I was pretty excited that there were 8 seats still in the expert fare display when I went to dinner and 90 minutes later:

J1, JN1, C1, D1, Z1, ZN1, P0, PN0, R0, RN0, IN0, I0, Y9, YN9, B9, M9, E9, U9, H9, HN9, Q9, V8, W8, S7, T3, L2, K0, G0, N0, XN0, X0

Nothing changed on the seat map (I know not a great indicator). Really, 6 seats got sold that fast? I don't remember the Zs when I looked last. Did they open up the R and people on the waitlist got upgraded and I'm basically screwed since I didn't get an email?

I understand it's UA sandbox, but the lack of transparency on upgrades makes me wonder what actually goes on.

Looks like its a good thing that the GPUs are going to be extended...
