Hi all, currently trying everything to see if we can score an upgrade in a few days from NRT to SFO. Low odds, but thought I'd try anyway.

1) Where does one see upgrade offers? Is it just through selecting the seat and seeing what they cost you, or is there another way?

​​​​​​2) This is the current availability information:

• J4
• JN4
• C4
• D3
• Z3
• ZN3
• P2
• PN0
• PZ0
• IN0
• I0
• O0
• ON0
• A0
• R0
• RN0
• Y2
• YN2
• B2
• M2
• E2
• U2
• H2
• HN2
• Q2
• V0
• W0
• S0
• T0
• L0
• K0
• G0
• N2
• XN0
• X0

There's 4 open business seats and 0 prem econ. Is the a chance that PZ opens (I vaguely remember reading having P2 is a potential requirement) and that I can snipe it?
