pandaperth Firstly thank you for confirming that the tool is buggy - not me (although still debatable...)

Next - confirming that we can keep stopping over in SYD is a game changer!! For some reason I thought I couldn't have multiple stopovers in the one place. Now we can do the little Noumea break as a little holiday on it's own!

As for the CDG-LHR-ATH routing, as in my reply to Mwenenzi, I think we might do an overland there - we'll be spending two months in the EU so might as well make our way down to ATH on our own, which gives us the extra segment to add on in Asia at the end of the ticket.

Re extra segments as you suggest, we might just add a stop in HNL for our first segment - might be a nice way to start the whole thing!! And then, I like the idea of substituting GRU-MAD-CDG with GRU-DOH-CDG - then we can do that sector with Qatar!! Win win!!

Our itinerary now looks like this - please correct me if I've made an idiot out of myself (highly likely)
NRT-HNLo-SEAo-LASo-JFKo-GRUo-DOHx-CDGo-HELo-ATHo-DOHx-SYDo-NOUo-SYDo-BKKo-SGNo-NRT
Mileage 45,943
And yes - back in 2014 your advice was what got me over the line in our first RTW - could not have done it without your invaluable help! We've done 3 Qantas Oneworld Classic flight 35000 mile itineraries since then but Qantas is currently so difficult to find classic reward flights that we decided to do another Global Explorer this time and hope that Qantas gets a bit less stingy releasing award space in 2025.... So again, THANK YOU!
