Hi all

I am planning a xONE4 for next year. I have been messing around with some routings and came up with the following:

MEL-LHR-DME-MAD-VIE-LHR-LAX-ORD-PDX-DFW-MIA-BOS-SFO-NRT-DEL-HKG-MEL

Neither Mileage Monkey nor the Oneworld booking tool throw up any errors on this routing. Yet I don't think it is valid as you would have to touch Asia as part of the MEL-LHR.

Is this valid or am I right in thinking it is something that isn't picked up until you try to physical book and pay for the ticket?

Thanks in advance
