For sure. When I lived in Australia, I found that the weight limit on that flight was not minor at all: they often had to fly it with 100 open seats in coach. DFW-SYD is by far my favorite way to get from the eastern half of the US to Australia. It's a comfortable ride even in coach, and I'd rather maximize my time on the A380 and minimize my time on domestic narrowbodies.
