Sorry if this has been discussed previously but I could not find any post dealing specifically with this question.

Does EB award points on *A codeshares as if the flight was operated by the codeshare airline or does the operating carrier come into play? This is assuming the operating carrier is *A also.

Specifically, what will be the point earning on LH codeshare (BD operated) flights between AMS and LHR, assuming a LH booking that earns 100% points according to scandinavian.net (Y,B,M,H,Q,V,S)? The bmi website states 25% earning for V and W booking class (based on mileage of 800).

Finally, any ideas on how to maximize the point earning - given that I pay for my own flights - when commuting weekly between Amsterdam and London? I guess flying LH with one stop in each direction should give me in 2400 points per roundtrip in Economy?

Thanks!
