To let you get some rest on this front (and get the thread back on topic) how 'bout this; in the cases
where it makes sense (same price) a UA member (since that was what was being discussed when this came up) *might* do 2 one-ways vs. purchase r/t to yield the extra bonus miles as
tom911 indicates is the practice in some cases in this post:

In the cases
where it doesn't make sense (higher price one-way vs. r/t,) of course no one in their right mind would.
Not that this should have required this level of explanation.

No one in their right mind would play UA's games when you have better options with SQ, OZ, TG and several other, better *A carriers to choose from. And often at the same or better price to boot.
I'd take a real premium experience over "premium" miles any day - especially with how UA has devauled them over the last few years.
