Thank you Brendan.
the link are as below:

http://www.airfrance.co.uk/GB/en/com...azerbaijan.htm

so if a code share flight is AF087 but operated by Azerbaijan airline, I could receive the flyingblue miles; but if a code share flight even listed as Airfrance in website but the boarding pass shows J2 087, I am not eligible to receive flying blue credits. am I understanding it correctly?

thanks
