I personally have 400K+ in each of the following programs: US/AA (counting these as one), Chase UR, Amex MR, and Delta. I'm a little light on United but I consider Chase to be a good option for United. Thus, if I want a couple of biz class overseas tickets, I have quite a few options. (I have 200+ in each of AA and US.)
+1. Diversity is ideal if you can do it without sacrificing your desired elite tiers to get it.
You're in a good spot with US elite status (and thus free access to *A partner awards), Delta, and two flexible sources of miles...
