Forgot to add the managers comment was specifically re the BKK flight as this was designated (his words) "short haul" so if you are travelling to London or Dubai, I think you would still be eligible
That's strange. We did exactly your trip but from Adelaide - (Syd) - BKK - (Syd) - Adelaide in December January 2015 with domestic Q and Emirates J international (and also F upgrade). Chauffeur Adelaide, Chauffeur BKK both to and from airport.
The chauffeur service was only booked through Qantas website. Maybe that's when it went pear shaped.
We are doing DBX trip on Emirates at Christmas. Maybe we should book through the Qantas website. But looking at the Emirates website it allows us to book. Might stick with Qantas.
