You do not have enough points in any one account that you've listed to make it from the US to MLE in biz class from what I can see. If you need to quickly build up some miles I'd apply for the associated CCs for the carriers, though it will take a bit of time for the miles to post and you might lose the availability while you are waiting.

Good Luck!

Also, don't cross-post in a bunch of fora. Bad form.
