I have seen and read the email HajoFlyer received from miles&more, confirming that, at least for this promotion, they (miles&more) would 'count' the Flight-number (and not the actual carrier).

But I also know, that until now that wasn't the case (at least not with miles&more).

I very much doubt, that the (emailed to HajoFlyer by miles&more) informations will 'work' out the way they promis/explain (they also say 'something' about the 3 OS-members in that email which contradicts other informations I got so far) - but with that email-info in hand, HajoFlyer will have strong evidence to fight for his case afterwards.
