Rule of thumb on AS is ticketing carrier matches operating carrier, you're good. If not, here there be dragons (the exception being OAL ticket, AS metal, AS will credit AS MP for that). You can sometimes get around this by sending in the boarding pass showing the MP # and the operating carrier flight number , but this is where things start to fall apart and you can get hosed.
