So my advice to the OP would be, fly everything with your A3 FF number, and retro-credit the non-earning segments to AC. Do you have A3*G? Then it's a no-brainer ;-)
I have heard many times the same thing that :D! is reporting. I suspect it may depend on what FFP you're crediting the 0 miles to. Perhaps Miles&Bonus does not touch 0 earning flights, but (as a random example) Miles&More does mark them as credited, even if that means crediting 0 miles. So it may matter which way around you do it, in which case given the number of people on here saying it's safe when crediting to A3, it is probably worth trying.
