I fail to see much difference between old economy and new economy, so I think a rollout across A380s seems unnecessary due to the large costs involved.
Maybe in the 575t A380s where the weight savings could prove useful if they throw the a/c on SYD-DFW? But that would mean 2 Y products in the A380s which suck. That said, if the A330s get the new product before the A380s get any new Business or Economy, wouldn't that mean MEL-HKG and BNE-HKG would be effectively have a better product than SYD-HKG on the supposed flagship A380s. Food for thought.
Anyhow, so I think I have previously said that there'll be 5x 717s with business class based in Canberra, well it seems only 4x will be based in Canberra with 1x based in Hobart, which is surprising as Hobart isn't a particularly high yielding destination, dominated by Q400s. Anyhow, they'll appear on the Canberra routes from November 15, 12x weekly to Brisbane, 4x week to MEL and 1x week to SYD with operations ramping up over the following 4 months.
Scoot has also applied for 5x weekly service to Perth with its 772s.
