sfoJoe:

My recommendation would be to join the RCC. Not only do they have clubs all around the world (unfortunately with varying quality ), but when travelling Star you could use all the business class lounges across the Star network (AC Maple Leaf, AN Golden Wing... and the list goes on). There is no oneworld equivalent because, for example, AAdmiral's Club membership does not get you into any other OW clubs.

Hope this helps...
