Merry Christmas Flyertalkers!

With the recent changes to the pluspoints It became more difficult to use GPU on UA flight for me.
So, I am trying to use my gpu(plusspoints?) on ANA flight.

And I have some questions.

I used United.com expert mode it does show united flight number but NH operated

Option1:J9,C9,D7,Z2,P0,O0,A0,R0,Y0,B0,M0,U0,H0,Q0, V0,W0,S0,L0,K0

Option2:J9,C9,D9,Z9,P9,O9,A8,R0

I have to book Option2. correct?

This time I do J-F upgrade. And I need O class is higher than 0. right?

How about if I want to do Y-J upgrade? I heard I need I but I don't see I class at all?

Can I find the availability on the ana website like united expert mode?

Regards,
Chris
