Interestingly, when I tried to see about booking the nonstop using a GPU, forcing it to search for v/w/w/h fares, and requesting a GPU supported upgrade, .bomb returned "Not Eligible For Upgrade" under the "Business (upgrade eligible economy fare)" column.

I've never seen that - other connections gave a price, e.g., via HKG, but showed it with the little yellow arrow indicating that there was an upgrade waitlist.

I've never seen this before - is it common, or is something special going on here?
