Has there been any new information on how upgrade certificates/GGUs work this year? Looking at the website and the T&Cs (which seem to indicate a hyperlink should exist to provide further details, but doesn't), my initial guess is the upgrade certificates will work on only Alaska Airlines marketed and operated flights but not Hawaiian and for now, the new international routes are considered Hawaiian as well. Is that about right?

I guess AS has a bit of time to clarify before anyone reaches the milestone. Personally I am really hoping for some form of long-haul upgrade certificate.
