Now that I'm lifetime *G with UA, I consider at the start of the year whether to make worthwhile status on another grouping. As it happens I normally end up back with UA/*A because it works better for me (this year I'll hit 1K on UA again but only fly them for 5 or 6 segments). Last year it was a OW year.
In an ideal world, my retirement plan would be to have lifetime status in both *A and OW.
