QF flights with 60** numbers are non RPT training or promotional flights.
155 of us Travel Agency leeches took Miss Nancy SYD to AKL for the night on QF6013 months before the 1st commercial flight. I believe we were the first International Qantas A380 passengers.
A nice night was had at the Westin and we brought her home the next day.
That is most likely crew training but isn't it nice to get the girls to come visit!
All the best
