Catching up on this thread as my trip approaches.

I checked and although I'm redeeming AA f.f. miles for a Business Class ticket, the flight # to Zurich is Swiss not AA (must not be a codeshare?). Someone mentioned that I can't get into Admirals Club with this type of ticket unless thei AA-Swiss alliance was completed...has this been completed? Any updates or recent changes to my original question. I have several hours layover, it sure would be nice to be able to go into a lounge and relax.
