On several itineraries, Delta has told me that the metal is not the question -- what makes a flight upgradable is whose ticket you are flying on.
Thus when I was on Delta metal, but in an AF or AZ codeshare seat, I could not be upgraded. If I had been on AF or AZ metal, but in a Delta codeshare seat, an upgrade would have allowed.

That may work on AF and/or AZ, but not on KE. I always ask and keep hoping it will change, but so far it has not.
