Hi EK_Flyer
I also got the Skywards email and indeed Premium class fares are very attractive, and much lower than Australia departure (I wonder why?)
I am looking at doing a AKL-DXB-SYD-AKL. Are you planning to go on the A380 again?
But not sure Skywards let you stopover in SYD on return. I will phone them tomorrow morning to find out.
Cheers
Sam
