Trip now booked for 11-18 July - thanks for your help.

I was a bit paranoid about the code-share issue after my experience around 15 years ago on a paid-for *A RTW ticket. One of my flights had an SK flight number and I thought it reasonable to assume that it would be a real *A flight and I would be getting miles for it. It turned out to be a codeshare with another non-Star airline (Air Estonia??) and there were no FF miles. It was only a short flight, but at that time I was counting miles carefully for renewal of status. I never thought that a *A RTW would include code shares, It raises a little red flag when I see "operated by" on on a flight booking page.
