When facing a situation in which a domestic leg has not cleared on an international itinerary, how can one tell whether the domestic segment has been properly coded for the upgrade? It used to say something like "SYSTEMWIDE UPGRADE REQUESTED". Now with the change to manage upgrades, I don't know. Is it the case that if 2 seat maps are displayed for the flight, this is coded correctly?

Also, the poster above (CAETrvlr) mentioned upgrade inventory in the GDS. I had assumed after the Expert Flyer this was much harder to come by, does someone have a handy thread to look at (three letter searches never work)?
