There is no such thing as *G upgrades. Unless he has status on CO or UA he's not in line for EUA.

You can have him added at the airport for a companion upgrade, just like on CO metal.

For lounges you can use PClubs along the way, including PTY, but partner lounges only if you are ticketed in F, and no other *A lounges as a *G since you will not be departing on a *A flight.
