I see a lot of articles and threads on WHAT you should credit your flights to based on strategies and what not...

I am about to hit EXP and would like to stop collecting Advantage Miles and instead get BAVIOS, CXAM, or EGM....

But I cant seem to find any information on HOW to actually do that...

like when I am booking my American Tix for the rest of the year how do I get points on other Airlines for my american flights

Thanks,
Jay
