Hi - I'm trying to use the tool to check if my itinerary is valid or not, but it's insisting that there isn't a single OW flight between Sydney and Thailand/Malaysia or Singapore which seems *quite* unlikely, so I thought I'd check here if this looks like a valid itinerary or if there are issues with it that I might not have spotted:

OSL-LHR-SIN-MEL-SYD-NOU-SYD-SIN-HKT-HKG-KIX-LAX-BOS-LHR-OSL

(first SIN stop transit only)

I'm within the 16 legs, but not sure if I have too many flights in Asia and Australia

Hoping I can use my BA vouchers to bring the pricing down even further!
