I was just coming here to post the same. The tickets showed biz when first redeemed. Flight schedules changed; they now show coach. However, when I use the Qatar PNR they show as business. Even though all looks well, it's unnerving to see the AS site proclaim it as coach. The very good news is that I was able to make my seat selections. I flew a few months ago and it was quite an ordeal and multiple phone calls to get seats in the suites without an attempt to charge. (I am OneWorld Emerald.)
