Thanks. I think you have answered the question. I want to make sure that I get Diamond Club status miles and hoped that by booking and flying on a CO flight I would get these.

BUT what looks like a CO flight turns out to be operated by VS - so although I'll get my destination miles I won't get status miles.

I think this is a bit of a 'con' - you book what you think is a Star Alliance flight and - because it turns out to be a VS service - end up with no ststus miles.
