I just want to acquire as many miles as possible to afford more frequent vacation travel. I don't have any paid business travel but my miles come mostly from ~$100K credit card charges. Thanks to an uptick in recent travel (due to a cancer diagnosis and some freed up time) I used up all my 900K miles with AA and now need to actually start paying for my flights which I can't well afford. I am fine traveling economy as long as I can travel at all.
