I'm a long-time frequent traveler, but I have limited experience making *A award redemptions. My only experience is using US miles to redeem on LH for business from CLT to MUC. My home airport is CLT fwiw. I have a ton of US miles (million-ish), a ton of Membership Rewards points (million+-ish), and lot of Ultimate Rewards points (700k or so). I had been wanting to save the UR's for Hyatt redemptions, not airline. I was going to try to make some award reservations for two (dad and I) for travel from CLT to MUC, or CLT - MUC - BRU...in business. US is blocking LH business redemptions or vice versa...either way, I'm of the impression that redeeming US miles for business award travel on LH yet in 2013 is a no-go, even if KVS shows availability. So I'm a newbie. Given the above and my desire to get two business class tickets to/from Brussels with one connection...what are my options? Is US blocking all *A redemptions (Brussels Air for example) or just LH? If I were to use my stash of MR points, where would it be best to transfer to for redemption on what airline?
