I have an ANA flight for a party of 3 from DEL-HND on 1/1. Right now the fare classes are

J6 C5 D3 Z1 P0.

I have waitlisted the 3 of us using PlusPoints. There’s still time of course but J6 isn’t promising. What’s the latest ANA will clear upgrades? Is it like united where they clear all the way down to the gate if they do? Or is there a cutoff at T-*insert number* hours? Thanks!
