your routing qualifies as one of the shortest DONE4s issued (at least by FT standards).
60k miles may have gotten the Qantas guy into a real fluster
I understand traveling West I could have done things like entering the US in LAX and leaving from JFK, however I had too many hard dates in too many places for that to work this time. My only concession to shamelessly collecting status credits is doing HKG-LHR-DXB-LHR where my schedule allowed HKG-DXB-LHR.
My last trip just before Christmas, booked by my now ex-TA was EDI-LHR-LAX-LAS-LAX-MEL-LHR-EDI. This was all booked point to point and cost quite a bit more. I think it's a poor reflection on the agent really that when my itinerary grew from a simple UK - Aus return they just added the US segments rather than suggesting the explorer ticket. Shows that in some cases you need to ask specifically for what you want whereas you could expect using an agent for their professional advice they'd at least suggest an alternative product which is cheaper and offers further flight segments.
