So I've gotten to the stage now where I've decided my itinerary for next year's holiday, and thought before I get too excited, I should get a travel agent (other than the one I work for.. my consultants are way too busy...

) to validate my planned ACIR26 itinerary ex AKL. I contacted Amex Platinum Travel
The routing I'm planning is
9/4 AKL-SYD
20/6 SYD-LAX-LAS
27/6 LAS-JFK
08/07 JFK-HKG
16/07 HKG-SYD
15/09 SYD-AKL
Apparently this is not allowed, as I'd be "stopping" in Sydney twice in the itinerary, and you're only allowed to stop in any city once. Advice I was given was to fly to a different Australian port, but there are no others with an F service from HKG.
I have gone back them and said what if I 'transit' through Sydney on the way back, ie fly HKG-SYD on QF in F, then be ticketed to connect to AKL (maybe on a flight much later that day). Would that be allowed? I could then just check-in for the HKG-SYD, and "miss" the connection.
Does this work? Is it possible?? Advice greatly appreciated.
PS - forgot to mention, when I plug in a RTW in the Oneworld planner, it has no issue with me "stopping" in Sydney twice. I thought the principle for RTW and CIR would have been fairly similar.
Cheers
