I'm just about to get Freccia Alata status in Alitalia's MilleMiglia scheme (SkyTeam Elite Plus, 75K elite mile qualification level). I'm slightly wary that Alitalia might disappear down the tubes at some point in the next 12 months, so I'd like to find a Star Alliance or oneworld airline that will comp me on the basis of my AZ status (I don't believe that SkyTeam carriers will comp each others statuses) and keep my options open.

I'd ideally want to get Sapphire in oneworld or Gold in the Star Alliance, I think.

Any suggestions?
