I've just come back from a trip to Auckland and found the Jetconnect offering better than domestic J. BNE - AKL 738. IFE provided (seatback) versus BYO device (apple & android only). Alcoholic welcome drink versus water/juice. Far more attentive service. Think there were 3 flight attendants for Business. Was in 3D. My meal choice was no longer available. Best to be in 1 or 2 for guarantee. Attendant was super apologetic though and went above and beyond to try and accommodate me. Other than IFE, seats were basically the same as domestic though.
Returned AKL - SYD on the A330. Was meant to be Emirates A380 (insert expletive). Anyway lie flat seats/beds (not that you need it for the 1640 flight). Was meant to be 3.5 hours but somehow we managed it in 2.5. IFE (seat back). Service was better than domestic but didn't feel as good as the 738 service. I haven't used domestic A330, so can't make any comparisons. Was 3 of us flying so booked 5E, F & K. Because of the way it is set out though, I should have gotten 5E, F & 4K to be across from each other.
Have to say the Auckland business lounge has nothing on the LAX One world lounge. Poor range of spirits, really notable was the Jim Beam (white) as the bourbon. Usually it's at least Jack Daniels elsewhere I've been. There is also a distinct lack of charging ports or power-sockets and you can't see any planes.
