Keep in mind that this is temporary. It's only scheduled through 10/8, coinciding with A380's 4x/week return to SYD-DFW from 11/8.Putting another A380 out SYD sounds great to me. The business class seat on a QF A380 is so much more comfortable than the horrible no recline AY business class seat.
The AY seat is imo only suitable for short day flights, it is horrible if you want to sleep as the mattress topper doesn't attach, the seat belt retracts tight making it difficult to roll-over, the angle favours sleeping only on one side and it is very hard for anyone with knee or back issues to return to seated position with nothing to get purchase on whilst trying to crawl out of the foot well.
